Publication number: 20230025110Abstract: A delivery system and method for delivering a prosthetic heart valve to the aortic valve. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic valve through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.Type: ApplicationFiled: September 30, 2022Publication date: January 26, 2023Inventors: Teodoro S. Jimenez, Walter Lee, Mark M. Dehdashtian, Kristopher J. Yee

Publication number: 20200146677Abstract: A surgical apparatus includes a cartridge; a staple strip held within the cartridge; and staples affixed to the staple strip. Each staple is affixed to the staple strip at a single joint. The staples on each staple strip are arranged in longitudinally-extending rows. The staples in adjacent rows are staggered. A wedge assembly includes a plurality of wedges laterally spaced from one another. Each wedge includes a shear bump on an upper surface. Each of the shear bumps has a first length. The shear bumps are aligned with one another within a distance equal to the first length. The wedge assembly is slidable relative to the staples to cause at least one wedge to make direct contact with at least one of the staples to rotate the staple about the joint, and then break the staple from the joint upon contact between the staple and shear bump.Type: ApplicationFiled: June 29, 2018Publication date: May 14, 2020Inventor: KRISTOPHER J.
