Patent Landscape · Structural Heart DevicesTranscatheter Valve Delivery Systems: Patents, Leading Filers and Where Claim Space Is Still Open
- Concentrated at the top. The five leading assignees hold 592 of 1,851 records in scope (32.0%), and the leading ten hold 918 (49.6%) — roughly half the field sits with ten companies.
- Filing has cooled from its 2019 peak. Annual filings ran from 136 in 2019 down to 32 in 2024, a -50% move between 2021 (64) and 2024 (the last complete filing year).
- Delivery-specific claims outnumber the implant itself in some subclasses. A61B diagnosis and surgery claims sit in 43.4% of the 1,851 records — nearly as dense as A61F implant claims at 57.2%.

Leading Jurisdiction
Filing growth compares 2021 (64 records) with 2024 (32) — 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 1,851 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
Transcatheter valve delivery systems sit at the intersection of implant design and catheter engineering: sheath sizing, flex articulation, deployment control, repositionability and the mechanics of avoiding vascular complication or crimping damage during advancement. This landscape covers 1,851 published records filed or published between 2015 and mid-2026, searched across both the delivery mechanism claims and the failure modes practitioners actually worry about in the cath lab.
Records are drawn from filings at the United States, European, WIPO/PCT, Australian, Canadian and German receiving offices, giving a cross-jurisdictional view of where applicants are seeking protection rather than just where they are headquartered. Publication lags filing by roughly 18 months, so the most recent one to two years in any trend chart will always understate real filing activity.

The Data
Filing trends and technology composition
Two views of the same 1,851-record dataset: how filing volume has moved year over year, and how the underlying technology splits across IPC subclasses.
Filing trend, 2017-2026
Annual filings climbed to a peak of 136 in 2019, then eased. The tracked decline from 64 filings in 2021 to 32 in 2024 (-50%) covers the last span where the data can be treated as reasonably complete; 2025 and 2026 figures are still filling in as publications catch up to filing dates.
IPC subclass composition
A61F (implants and prostheses) appears on 57.2% of the 1,851 records and A61B (diagnosis and surgery) on 43.4%, reflecting how tightly delivery-system claims are drafted alongside the valve implant itself. A61M (devices for body fluids) reaches 23.5%, while A61N, A61L and A61K sit in single digits. Because records commonly carry more than one class, these shares add up to well over 100% and should not be read as a partition of the field.
Shares are the percentage of the 1,851 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the numbers mean for a filing decision
Three signals worth weighing before drafting into this space: how concentrated the field already is, how the technology composition splits, and what the citation record says about foundational claims.
Concentration
32.0% / 49.6%
share held by top 5 / top 10 of 1,851 records
Half the field sits with ten filers
The five leading assignees account for 592 of the 1,851 records in scope, and the leading ten account for 918. That leaves a long tail of the remaining 90 ranked companies plus unranked entrants splitting the other half, which is where most freedom-to-operate work will actually happen.
Based on the full 100-company assignee ranking returned for this dataset.
Filing momentum
-50%
filings, 2021 (64) to 2024 (32)
Volume has eased from its 2019 peak
Filings peaked at 136 in 2019 and have since declined, with the 2021-to-2024 span showing a -50% drop. 2024 is the last year in this dataset that can be treated as filing-complete; 2025 and 2026 counts will rise as publications catch up.
Publication lag of roughly 18 months applies to the most recent two years shown.
Technology mix
57.2% vs 43.4%
A61F implants vs A61B diagnosis/surgery share
Delivery-mechanism claims run nearly as dense as implant claims
A61F implant and prosthesis claims cover 57.2% of the 1,851 records, but A61B diagnosis and surgery claims are close behind at 43.4%, and A61M body-fluid device claims sit at 23.5%. That overlap signals delivery mechanics are claimed almost as heavily as the valve hardware itself.
Shares sum above 100% because records can carry multiple IPC classes.

Players
Who is filing, and where the activity is thinning
The leading assignees combine large device makers with smaller specialist entrants; several of the most active names show flat or declining recent-year filing counts, consistent with the overall cooldown from the 2019 peak.
Leader
172 records
leading assignee, records in scope
A single filer well ahead of the field
The leading assignee holds 172 records, well above the fifth-place company at 80 and the tenth-place company at 58. That gap suggests the leader has built a broad claim footprint across multiple delivery-system variants rather than a single narrow position.
Counted in patent families within the assignee ranking.
Mid-tier gap
80 vs 58
fifth place vs tenth place, records
A moderate drop-off after the top five
Filing counts fall from 80 records at fifth place to 58 at tenth place, a narrower gap than between the leader and fifth place. This suggests a reasonably competitive second tier rather than a sharp cliff after the top handful of filers.
Figures from the 100-company assignee ranking.
Recent momentum
0% to -100% YoY
latest-year filings among several tracked assignees
Several established filers show little to no recent activity
Among the assignees tracked for recent-year momentum, most show either zero filings in the latest year or year-over-year declines, including one entrant down 100% YoY. This is consistent with the broader cooldown in filing volume rather than any single company's retreat.
Momentum reflects the latest partial year in the dataset; treat with caution given publication lag.

What's Next
Where to take this next
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, licensing, or identifying a filing gap.
Map the leader's full claim footprint
With 172 records, the leading assignee's portfolio likely covers several delivery-system variants. A claim-by-claim review of its most-cited filings is the fastest way to find where its coverage actually ends.

FAQ
Common questions about this landscape
Within this dataset of 1,851 records, one assignee leads with 172 records, well ahead of the fifth-place company at 80 and tenth-place company at 58. The top five assignees combined hold 592 records, or 32.0% of all records in scope, and the top ten hold 918, or 49.6%. That leaves roughly half the field distributed across a long tail of smaller filers, so a single leader does not equate to full control of the space.
Filing activity peaked at 136 records in 2019 and has since declined, with a tracked drop from 64 filings in 2021 to 32 in 2024, a fall of 50% over that span. 2024 is the most recent year in this dataset that can be treated as filing-complete. Figures for 2025 and 2026 appear lower only because publication typically lags actual filing by around 18 months, not because activity has stopped.
A61F, covering implants and prostheses, appears on 57.2% of the 1,851 records, making it the single most common classification. A61B, diagnosis and surgery, is close behind at 43.4%, and A61M, devices for handling body fluids, appears on 23.5%. Because a single record can carry multiple IPC classes, these percentages overlap rather than sum to 100%, and the overlap itself shows how tightly delivery mechanics are claimed alongside the valve implant.
The comparatively low-density IPC subclasses in this dataset are D04C (braiding and lace, 1.2% of records), B29C (shaping of plastics, 1.1%), A61K (medicinal preparations, 2.2%) and A61L (sterilising and disinfecting, 5.2%). These lower shares suggest less-crowded claim space around braided sheath construction, molded delivery components, drug-eluting coatings and sterilization-compatible materials, relative to the dense core of implant and delivery-mechanism claims. Low density is not proof of an easy filing, but it is a reasonable starting point for a freedom-to-operate search.
US20250228665A1, published 2025-07-17 and assigned to Caisson Interventional, LLC, describes a transcatheter delivery system for prosthetic heart valves with a separable anchor portion and valve portion that can be mated together and, in some embodiments, retrieved after deployment. It is representative of current claim drafting in the field rather than the oldest or most-cited filing. Anyone designing a delivery system with a comparable anchor-and-retrieval mechanism should review its specific claim language before proceeding.
