Run your analysis now →Filing growth compares 2021 (54 records) with 2024 (33) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 907 records in scope (CR5), not by the ranked leaders only.
This landscape tracks 907 published patent families filed between 2015 and mid-2026 that combine transcatheter or edge-to-edge mitral valve repair with specific technical elements: grasping mechanisms, residual regurgitation management, leaflet insertion, single leaflet detachment, gradient increase, and imaging guidance. It is a device-and-method view of the field, not a broad cardiology sweep — the search string ties structural repair language to the functional problems that actually distinguish one clip or annuloplasty approach from another.
Records are drawn from filings at the United States, European, WIPO/PCT, Canadian, Australian and German offices, giving a cross-jurisdictional picture of where applicants seek protection rather than just where they are headquartered.
Two views of the same 907-record dataset: how filing activity has moved year on year, and which IPC subclasses carry the claims.
Filings ran from 56 in 2017 to a peak of 117 in 2020, then eased to 54 in 2021 and 33 in 2024 — a 39% decline across that three-year window. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the most recent years understate actual filing activity.
A61F (implants and prostheses) appears on 75.0% of records and A61B (diagnosis and surgery) on 53.5%, reflecting that most filings claim both a physical repair device and a surgical method or delivery approach. A61M devices for body fluids sit far behind at 8.6%, and imaging/informatics classes (G16H, G06T) each cover under 1% of records — a record can carry more than one class, so these figures do not sum to 100%.
Shares are the percentage of the 907 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaA tissue clip for adjoining tissues including a body portion, a biasing mechanism interconnecting the body portion to a tissue grasping mechanism, with the grasping mechanism moving between a condition extending away from the body and a condition biased against it. The filing also covers a tissue clip and deployer combination, a method of interconnecting tissue via puncture and clip deployment, and a method of treating an aneurysm by clip deployment at the aneurysm site.Filed by Children's Medical Center Corporation, published 2016-04-12 — a grasping-mechanism claim that predates much of the later edge-to-edge repair filing activity in this dataset.

Citation counts favour older filings simply because they have had more time to accumulate citations within the searched corpus; treat them as a signal of influence on the field, not of current commercial relevance.
Each row carries its publication number; clicking a row searches Eureka by that number.

The five leading assignees account for 446 of the 907 records in scope, and the leading ten reach 63.9%. A new entrant filing near the core edge-to-edge or annuloplasty claim language is filing into dense, established prior art rather than white space.
2020 was the peak year at 117 filings; the complete-year trend since then has fallen from 54 (2021) to 33 (2024). That is a real cooling in new filing activity in the core claim space, not a data artefact — though 2025-2026 counts are still filling in.
The highest-cited records in this dataset are annuloplasty and tissue-remodeling patents from the early 2000s, cited well over 900 times each. Their influence reflects decades of accumulated citations inside a mature corpus, not that annuloplasty is where current filing activity concentrates.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to transcatheter mitral valve repair, with the prior art for and against each one.
A small group of device makers and one government research body account for the bulk of records; recent-year momentum shows most of that group slowing rather than accelerating.
The leading assignee holds 123 records, nearly double the fifth-place holder at 66. That gap, combined with the top-5 share of 49.2% of all 907 records, points to a filer that has claimed broadly across grasping mechanisms and delivery methods over a sustained period.
Latest-year filing counts among the top names are low in absolute terms — several show 0 or 1 filing in the latest year, and two show -100% year-on-year. This is consistent with the broader post-2020 slowdown rather than a company-specific pullback.
Only 10 co-assignee pairs appear in the dataset, the strongest linking a device maker to a US federal health research body. Co-filing with academic or government partners is a minor but present pattern, more common than device-to-device co-filing.

The dataset points to a mature core and a thinner periphery. The next steps depend on whether the goal is freedom-to-operate or new filing.
Given that the top five assignees hold 49.2% of all 907 records, any grasping-mechanism or edge-to-edge design should be checked claim-by-claim against their portfolios before committing to a delivery approach.
Run a freedom-to-operate search in Eureka →G16H and G06T together cover under 2% of records combined, well below the physical-device classes. That gap is worth a closer technical read before assuming it is unclaimed.
Explore white space in Eureka →Because publication lags filing by roughly 18 months, 2025-2026 filing activity is still incomplete in this dataset. Re-running the trend in a future quarter will reveal whether the 2021-2024 decline continued or reversed.
Set up a monitoring alert in Eureka →The dataset ranks 100 assignees by patent family count, and one company sits well ahead of the rest with 123 of the 907 records in scope. The gap to the fifth-ranked assignee, at 66 records, is substantial, and the top five together hold 49.2% of all records. This concentration means most of the core edge-to-edge and grasping-mechanism claim language is already occupied by a handful of device makers rather than spread thinly across the field.
No — filing peaked in 2020 at 117 records and has since declined through the last complete year of data, falling from 54 filings in 2021 to 33 in 2024, a 39% drop. That is a genuine cooling in new applications rather than market maturity or technology decline; high filing density in earlier years means the core claim space is occupied, not necessarily that the technology itself has plateaued. Figures for 2025 and 2026 are still incomplete because publication lags filing by roughly 18 months.
A61F, covering implants and prostheses, appears on 75.0% of the 907 records, and A61B, covering diagnosis and surgery methods, appears on 53.5%. Because a single record can carry multiple IPC classes, these figures overlap rather than sum to 100%. Classes tied to imaging and healthcare informatics — G16H and G06T — each cover under 1% of records, marking them as comparatively under-claimed relative to the physical device and method classes.
US9307984B2, assigned to Children's Medical Center Corporation and published in 2016, claims a tissue clip with a body portion and a biasing mechanism that moves a grasping mechanism between an extended and a body-biased condition, along with methods of deploying that clip to interconnect tissue or treat an aneurysm. Its claims center on the specific biasing-and-grasping mechanical relationship rather than mitral repair exclusively, so it is a relevant prior-art reference for any grasping-clip design rather than a blanket block on edge-to-edge repair generally. Anyone designing a new grasping mechanism should read its claims against their own actuation geometry rather than assume it clears simply because it predates transcatheter-specific filings.
The imaging-guidance, gradient-detection and regurgitation-quantification sub-areas sit far below the physical device classes in filing volume, with the informatics-adjacent IPC classes each covering under 1% of the 907 records. Co-assignee activity is also limited, with only 10 identified pairs in the dataset, suggesting collaborative filing around software and sensing layers is not yet common. That combination points to instrumentation and software-adjacent claims as the more open territory compared with the densely filed grasping-mechanism and delivery-device core.
