BioCardia Announces Allowance of Japanese Patent on Proprietary Heart3D™ Fusion Imaging Software for Procedure Planning and Realtime Navigation During CardiAMP Cell Therapy Procedures
Rhea-AI Summary
BioCardia (Nasdaq: BCDA) announced allowance of a Japanese patent titled “Target Site Selection, Entry, and Update with Automatic Remote Image Annotation” on April 28, 2026. The patent covers the company’s Heart3D™ Fusion Imaging software for preoperative 3D-to-2D image transposition, intraoperative 3D model reconstruction, procedure planning, and real-time navigation within or adjacent to a sterile field.
BioCardia said Heart3D is intended to support CardiAMP® cell therapy and the Helix™ intramyocardial delivery system, and the company is working to submit these product candidates for approval in Japan after a positive PMDA consultation and is discussing U.S. approval pathways.
Positive
- Japanese patent allowance on Heart3D software (Apr 28, 2026)
- Patent claims cover 3D-to-2D transposition and intraoperative 3D reconstruction
- Company reported a positive consultation with Japan PMDA
- Plans to submit CardiAMP and Helix product candidates for approval in Japan
Negative
- Patent allowance does not equal regulatory approval or market clearance
- No U.S. approvals yet; approval pathways remain under discussion
- Press release provides no financial, commercial timeline, or revenue projections

Historical Context
| Date | Event | Sentiment | 24h Move | Catalyst |
|---|---|---|---|---|
| Apr 20 | Regulatory consultation | Positive | +5.9% | PMDA indicated CardiAMP data likely sufficient for ischemic heart failure clearance. |
| Apr 02 | Regulatory pathway | Positive | +3.5% | FDA meeting requested for accelerated approval of CardiAMP System in ischemic HFrEF. |
| Mar 24 | Earnings update | Negative | -0.4% | 2025 results highlighted cash usage, net loss, and modest R&D-driven cost increase. |
| Mar 19 | Conference call | Neutral | +0.0% | Announcement of upcoming 2025 results and corporate update conference call. |
| Mar 17 | Regulatory submission | Positive | +0.8% | FDA accepted Helix catheter pre-submission, supporting CardiAMP approval pathway. |
24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent regulatory and clinical updates have often been followed by modest positive price moves, while earnings-related news has seen flat to slightly negative reactions.
Over the past months, BioCardia reported multiple regulatory and clinical milestones, including PMDA alignment on CardiAMP data in Japan on Apr 20, 2026 and an FDA accelerated-approval meeting request on Apr 2, 2026, both followed by single-digit percentage gains. Earlier, FDA acceptance of a Helix pre-submission and 2025 earnings produced smaller moves. Today’s Japanese patent allowance for Heart3D fusion imaging extends this stream of ecosystem-building developments around CardiAMP and Helix rather than changing core financials.

SUNNYVALE, Calif., April 28, 2026 (GLOBE NEWSWIRE) -- BioCardia®, Inc. [Nasdaq: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today announces the allowance of Japanese Patent, “Target Site Selection, Entry, and Update with Automatic Remote Image Annotation.” This patent adds further protection to BioCardia’s proprietary Heart3D™ Fusion Imaging (Heart3D) software intended for treatment planning and real-time navigation during CardiAMP Cell Therapy procedures.
The allowed Japanese patent has claims on the use of Heart3D fusion imaging configured for transposing a preoperative three-dimensional image obtained by Computer Tomography (CT) or Magnetic Resonance Imaging (MRI) of the patient’s heart onto two orthogonal two-dimensional images to generate a combined three-dimensional model reconstruction of the heart on a display within or adjacent to a sterile field for navigating delivery systems and recording procedural locations.
“Heart3D fusion imaging technology is expected to support our leading CardiAMP® cell therapy for the treatment of ischemic heart failure and our Helix™ intramyocardial delivery system,” said BioCardia Chief Executive Officer Peter Altman, PhD. “After our recent positive consultation with the Japanese Pharmaceutical and Medical Device Agency, we are working to submit these product candidates for approval in Japan. These product candidates are also the subject of upcoming discussions regarding approval pathways in the United States.”
About CardiAMP Cell Therapy
Granted FDA Breakthrough designation, CardiAMP Cell Therapy uses a patient’s own bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure intended to increase capillary density and reduce tissue fibrosis of myocardial tissue to address microvascular dysfunction. Japan Pharmaceutical and Medical Device Agency has indicated that the clinical results from three completed clinical trials for the treatment of ischemic heart failure likely provide sufficient evidence of safety and efficacy to support a successful submission for approval.
Clinical development of the CardiAMP Cell Therapy for heart failure is supported by the Maryland Stem Cell Research Fund and is reimbursed by Centers for Medicare and Medicaid Services (CMS). CAUTION - Limited by United States law to investigational use.
About Heart 3D
Heart3D Fusion Imaging is intended to enhance real time 2D X-ray imaging by fusing pre-procedure three-dimensional anatomical heart models created from MRI and CT images for the interventional cardiologist with a focus on cardiac biotherapeutic interventions and biopsies.
Heart3D is expected to improve the interventional experience for treating cardiologists and enable clear communication between the treating cardiologists who perform the procedures and their heart failure cardiology colleagues to document how procedures have occurred. Heart3D may be reimbursed as existing cloud-based software for annotating CT images for guiding clinical diagnosis of coronary artery disease.
Heart3D is being developed in collaboration with corporate partner CART-Tech which also has issued and pending patents that add additional layers of protection around the product offering. Heart3D is intended to be used for therapeutic delivery procedures in conjunction with BioCardia’s proprietary Helix transendocardial delivery system.
Heart3D is currently for investigational preclinical use only. BioCardia invites partnering inquiries for pre-clinical research currently. An image of Heart3D is available on the Company’s website at https://www.biocardia.com/pipeline/heart3d-fusion-imaging/id/5011
