What changed
Medtronic filed patent application US20260090883A1 covering a valve prosthesis delivery system with three engagement arms on a support structure. The method involves proximally retracting a delivery catheter tube to release the engagement arms, which flare outwardly while an inflow frame portion remains constrained, followed by distal advancement to fully release the prosthesis. The application names inventors Yossi Tuval, Raphael Benary, and Ido Kilemnik.
This is a patent application publication, not a regulatory requirement. Companies developing similar transcatheter valve delivery systems should review the claims to assess potential IP implications. No compliance actions are required as this document does not impose regulatory obligations on third parties.

Abstract
A method of delivering and deploying a valve prosthesis includes delivering the valve prosthesis disposed in a delivery catheter to a native valve, proximally retracting a delivery catheter tube of the delivery catheter such that three engagement arms of a support of the valve prosthesis are released from the delivery catheter tube and flare outwardly while an inflow frame portion of the support remains within a distal portion of the delivery catheter, and distally advancing the distal portion of the delivery catheter such that the inflow frame portion is released from the distal portion.
