Publication number: 20230034126Abstract: A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.Type: ApplicationFiled: October 7, 2022Publication date: February 2, 2023Applicant: Cephea Valve Technologies, Inc.Inventors: Juan F. Granada, Gary Erzberger, Michael P. Corcoran, Dan Wallace, Matteo Montorfano, Alaide Chieffo

Publication number: 20220354638Abstract: A prosthetic heart valve includes a collapsible stent and a valve assembly disposed within the stent. A first cuff is disposed adjacent the stent. A second cuff having a distal edge facing the outflow end of the stent is disposed about the stent radially outward of the first cuff and the stent. The stent may include a plurality of fingers each having a first end coupled to a corresponding cell of the stent and a free end adapted to extend radially outward of the corresponding cell. The distal edge of the second cuff may be coupled to the fingers at spaced locations around the circumference of the stent to position the distal edge radially outward from the corresponding cells at the spaced locations. Various stent struts may be tapered to reduce the stent circumference in the collapsed condition, and to improve the fatigue resistance and/or bendability of the stent.Type: ApplicationFiled: July 26, 2022Publication date: November 10, 2022Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Gary Erzberger, Brett Allen Hillukka, Kristopher Henry Vietmeier, Kenneth L. Kelly

Patent number: 11446142Abstract: A prosthetic heart valve may include a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets attached to at least one of the cuff or the stent within an interior region of the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a flat mesh of braided wire material having a plurality of pores extending therethrough. The leaflets may be devoid of biological material at a time of implantation.Type: GrantFiled: September 16, 2020Date of Patent: September 20, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Caytlin Gale, Gary Erzberger, Kristen T.

Patent number: 11331466Abstract: Disclosed herein is an inflow cannula for an implantable blood pump assembly. The inflow cannula includes a tubular body that extends from a proximal end to a distal end. The tubular body includes a proximal portion adapted for connection to a pump housing, and a distal portion adapted for positioning within an opening formed in a heart. The inflow cannula further includes an expandable sleeve coupled to an exterior surface of the distal portion. The sleeve has a first portion coupled to the distal portion of the tubular body, and a second portion extending from the distal end of the tubular body. The second portion is deployable from a first, stored configuration to a second, deployed configuration in which the second portion expands radially to engage and conform to an endocardial surface of the heart.Type: GrantFiled: January 16, 2020Date of Patent: May 17, 2022Assignee: TC1 LLCInventors: Rachel Keen, Steve Franklin, Tracee Eidenschink, Ted Dale, Gary Erzberger, Kristopher Vietmeier, Julien Duhamel, Francheska Torres
