Patent number: 11369470Abstract: A loading tool for loading a collapsible prosthetic heart valve into a delivery device may include a body extending in a longitudinal direction between a proximal end and a distal end, an extension on the distal end of the body, and a slot extending through the extension from a free end of the extension toward the distal end of the body. The body may include a lumen extending between the proximal end and the distal end, the body lumen having a first diameter. The extension may have a lumen coaxial with the body lumen, the extension lumen having a second diameter less than the first diameter so as to define a shelf surface between the proximal end of the body and the free end of the extension.Type: GrantFiled: January 13, 2020Date of Patent: June 28, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Mark Krans, Theodore Paul Dale, Andrea N. Para, Mathias Charles Glimsdale, Thomas M. Benson, Peter N. Braido

Patent number: 11246706Abstract: A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.Type: GrantFiled: April 23, 2019Date of Patent: February 15, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Theodore Paul Dale, Andrea N. Para, Gaurav Satam, Jason Diedering, Thomas Mark Benson, Saravana B. Kumar
