The investigational program centers on the Lionheart Octopus™ refillable delivery system, implantable bioelectric microstimulators, and a monitored, fluid-filled chamber. Lionheart is targeting late 2029 for the first possible investigational treatment.
Planned first treatment site locations include Roatan, Honduras, Costa Rica, Dubai, Mexico and Lithuania 
HUNTINGTON BEACH, Calif. — Lionheart Health, Inc. announced a public waitlist for its Whole Body Regeneration System, known as Womb for Adults. Adults who join can receive research updates and early notice if applications open for an initial study. The program will explore whether a monitored environment, targeted delivery of investigational biologic materials, and programmable bioelectric stimulation can help researchers preserve or restore measurable organ function.

The Lionheart Octopus™ is at the center of the design

The Lionheart Octopus™ is a proposed implantable microinfusion system designed to sit beneath the skin in the lower-left abdomen. Its refillable reservoir and self-sealing access port are intended to allow replenishment while the device remains implanted. Organ-directed catheters would give researchers a way to study localized delivery or replenish a contained, organ-adjacent bioreactor such as KlothoPatch™ II. Lionheart’s IP foundation includes U.S. Patent 10,646,644, Stimulator, pump and composition, alongside newer development work on refillable reservoirs, organ-directed delivery, and bioreactor replenishment.
The chamber concept also includes four separate refillable compartments built into the housing for Wharton’s jelly, amniotic fluid, placental fluids, and Klotho-expressing stromal cells. In the concept illustration, each compartment has its own umbilical-style catheter extending toward the body. The separate compartments would allow researchers to evaluate individual materials and delivery approaches before studying combinations. The illustration depicts a proposed configuration for future research.

Implantable microstimulators would provide local bioelectric signals

The design pairs the Octopus delivery system with Lionheart implantable bioelectric microstimulators. The concept depicts paired positive and negative leads for six organ groups: the heart, lungs, liver, kidneys, pancreas, and brain. The microstimulators would give researchers a way to study local electrical stimulation separately from biologic delivery and test whether combining them changes tissue response. Proposed monitoring would track organ function alongside exploratory biomarkers.
Lionheart’s October 2026 IP inventory lists 63 patent and application entries and 518 issued claims across its core, licensed, and optioned portfolios. The portfolio spans programmable bioelectric stimulation, regenerative cells and biologics, targeted delivery, organ-function research, regenerative aesthetics, and investigational oncology. The bioelectric program includes targets such as Klotho, Sestrins, Sirtuins, BDNF, NANOG, GDF10, SDF‑1, PDGF, and VEGF. At its current research pace, Lionheart projects that its program could encompass approximately 100 protein-expression targets by 2029. That figure is a research projection.

The team brings decades of catheter and bioelectric research

Lionheart’s work builds on the Leonhardt team’s experience in cardiovascular catheter engineering, endovascular stent grafts, catheter-based cell delivery, and bioelectric stimulation. Leonhardt Ventures reports that technologies and derivative product families associated with its team have contributed to the treatment of more than one million patients worldwide. The team reports receiving two Utah Science Technology and Research (USTAR) grants and four University of California, Irvine (UCI) Capstone grants. Lionheart also received the AbbVie Allergan ULP Innovation Award and was selected as an XPRIZE Healthspan Top 40 Milestone 1 award winner and semifinalist in a global competition that XPRIZE says drew more than 600 registered teams from 58 countries. The core Leonhardt led team used bioelectric stimulation for limb salvage patients in England in 1987, regenerated their first mammal heart with muscle derived cells in 1988, implanted first biological pacemakers in large mammals in 1990, first animal implants of a percutaneous heart valve 1991,  first animal implants of intravascular lung in 1991,  first stem cell delivery catheter system tested 1993 ProCell, completed first human repair of an aortic aneurysm without surgery in Australia in 1995, first human heart regenerated with muscle derived cells in The Netherlands in 2001.

A staged research program and a late-2029 target

Lionheart’s research roadmap describes a possible first study focused on selected noninvasive components, including BodStim™ wearable muscle stimulation. Investigators could track strength and mobility alongside exploratory biomarkers. The Octopus implant, organ-directed catheters, implanted stimulators, and biologic components would require separate evaluation before any study of the integrated system. Its safety and effectiveness have yet to be established.
Lionheart is targeting late 2029 for the first possible investigational treatment, subject to research progress, site readiness, and applicable regulatory and ethics approvals. Locations under consideration include Roatán, Honduras, as well as sites in Costa Rica, Lithuania, Mexico, and Dubai, United Arab Emirates. The site and start date are pending.

Join the waitlist

The waitlist is free and provides research updates and early notice if study applications open. Any future study will have its own eligibility, screening, and consent process. Study participation and access to treatment depend on those requirements. Learn more about the Womb for Adults research program.
Lionheart Health’s proposed BioLeonhardt Whole Body Regeneration Chamber, also called the Adaptive Regeneration Womb™ or “Womb for Adults,” takes its inspiration from the idea of controlling the environment around living tissue. The goals differ by age. An artificial womb would support fetal development after extreme preterm birth. For older children and adults, the research question is whether temporary support can preserve or improve the function of an injured or failing organ. Lionheart’s chamber, refillable delivery architecture, and combined regenerative uses are investigational.

Inside the Lionheart Octopus™ refillable delivery system

The Octopus concept starts with a reservoir placed beneath the skin. A self-sealing access port would allow a clinician to replenish the reservoir while it remains implanted. A microinfusion pump would control delivery through a catheter directed toward a selected organ or a contained bioreactor. A coordinated controller would manage the bioelectric component, with electrodes providing local stimulation. Delivery and stimulation could then be evaluated independently before researchers study them together. U.S. Patent 10,646,644, Stimulator, pump and composition, describes combinations of stimulation, infusion, and regenerative compositions. Lionheart has also reported Octopus development work through a UCI Capstone program.
Lionheart’s September KlothoPatch™ II announcement describes two ways to replenish an organ-adjacent bioreactor. One uses the implanted Octopus reservoir. The other uses an endovascular catheter designed to dock with the patch. The proposed patch combines a nutrient hydrogel, a semipermeable membrane, a potentially retrievable cell cartridge, and local electrodes. In a contained configuration, the membrane would retain cells while allowing selected secreted factors to reach surrounding tissue. Candidate materials under separate study include soluble Klotho, Klotho-expressing stromal cells, platelet-rich fibrin-derived materials, selected growth factors, and extracellular vesicles. Proposed sensors would track oxygen, temperature, pressure, electrical impedance, and biochemical markers.
The pump handles local delivery. Blood circulation and gas exchange would require dedicated equipment. An early experiment could use an established donor-organ perfusion platform to measure what local stimulation or controlled delivery adds. Lionheart’s proposed LiverCell™ feasibility study is a more focused example of the same approach, pairing refillable delivery with a local microstimulator to study liver tissue.

The proteins and pathways Lionheart is studying

Bioelectric stimulation and catheter delivery address different questions. Stimulation asks whether an electrical signal can alter what the tissue produces or releases. Delivery asks whether placing a defined material near that tissue changes its response. Lionheart’s broader portfolio spans proteins, protein families, peptides, and signaling pathways. Its July CerebraCell™ announcement alone describes a proposed program involving more than 60 regenerative proteins. Each target still needs to be evaluated in the relevant tissue, including whether its activity should increase or decrease and whether the change improves organ function.

Four decades of catheter engineering and regenerative research

In May 2026, Leonhardt Ventures reported that inventions, technologies, and derivative product families associated with Howard J. Leonhardt and affiliated teams had contributed to the treatment of more than one million patients worldwide. The company-reported figure spans decades and includes cardiovascular catheters, aortic stent grafts, structural-heart technologies, and other product families. Lionheart’s current team includes cardiologist Dr. Leslie Miller as Chief Medical Officer, who leads medical strategy, and Dr. Jorge Genovese VP Bioelectric Regeneration Research whose bioelectric research background includes work at the McGowan Institute for Regenerative Medicine and the University of Utah. Brian Lassater CTO VP Engineering.  Dr. Stuart Williams and Dr. Doris Taylor co-Chair the Scientific Advisory Board.
Year
Milestone
1987
Lionheart traces its VascuStim™ limb-salvage program to early research on circulation and tissue repair that began in 1987. The company describes an early pilot in England.
1988
Collaborators Dr. Race Kao and Dr. George Magovern conducted pioneering animal work using skeletal muscle satellite cells to repair damaged heart tissue, according to Leonhardt Ventures’ historical account.
1990
Leonhardt Ventures traces Wendell King’s early biological-pacemaker work to 1990. A separate company timeline dates successful dog work under the BioPace™ program to 1999.
Early 1990s
Leonhardt’s team pursued early catheter-delivered heart-valve designs. Howard Leonhardt and Trevor Greenan were named on U.S. Patent 5,957,949, Percutaneous placement valve stent, issued in 1999. Alain Cribier’s team published the first human percutaneous aortic valve implantation in 2002.
1995
The Leonhardt team reports an early percutaneous aortic aneurysm repair in Melbourne using the TALENT™stent graft with Drs. Ken Thomson and Peter Field. Juan Parodi and colleagues had published their earlier transfemoral endovascular aneurysm repair experience in 1991.
2001
Leonhardt Ventures dates its early catheter-based human heart-repair case in Rotterdam to May 2001. The team delivered a patient’s own skeletal muscle cells to damaged heart tissue. The subsequent peer-reviewed pilot reported safety and feasibility experience with catheter-based delivery.
The Octopus brings together two strands of that history: using catheters to reach a specific site and using electrical signals to study how tissue responds. The next test is whether those tools, individually or together, measurably improve the work an organ does. In a kidney model that could mean better filtration. In a liver model it could mean better metabolic function. For children, developmental safety would require its own evidence. Across all ages, the proposed system remains a research concept, with whole-body regeneration and age reversal still unproven.
