The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.Type: ApplicationFiled: April 23, 2019Publication date: August 15, 2019Applicant: St. Jude Medical, LLCInventors: Peter N.

Publication number: 20190247185Abstract: Described embodiments are related to a prosthetic valve for surgical placement with a sewing cuff durably attached to a frame. The durability of the attachment is accomplished by sandwiching a fabric between the frame and a composite material. The fabric extends beyond the frame base to form a sewing cuff that is integral to a frame assembly. The sewing cuff facilitates tissue ingrowth while tissue ingrowth is discouraged elsewhere around the frame.Type: ApplicationFiled: April 25, 2019Publication date: August 15, 2019Inventor: Paul D.

Publication number: 20190247186Abstract: In some embodiments, a method for delivery and deployment of a prosthetic mitral valve into a heart includes inserting an introducer sheath having a prosthetic mitral valve disposed therein in a collapsed configuration into the left atrium of a patient's heart, through a gap between the native mitral valve leaflets, the left ventricle and apex of the heart. An epicardial pad device coupled to the prosthetic valve via a tether is moved distally out of the sheath. The introducer sheath is withdrawn into the left atrium of the heart. An inner delivery sheath is extended distally from within the introducer sheath and disposed within the left atrium. The prosthetic mitral valve is moved distally out of the inner delivery sheath and assumes a biased expanded configuration. The valve is positioned within the mitral annulus of the heart, and secured in place via the tether and epicardial pad device.Type: ApplicationFiled: April 25, 2019Publication date: August 15, 2019Applicant: Tendyne Holdings, Inc.Inventors: Robert M.

Publication number: 20190247187Abstract: A method for delivering an implant including, a catheter having a shaft defined by a proximal end and a distal end and a bore extending therethrough; a first joint in the shaft, and a second joint in the shaft located distal of the first joint. The first joint and the second joint are separated by a first digit sized to receive the implant and located between the first joint and the second joint. The second joint and the distal end are separated by a second digit being sized to receive the implant. The implant is advanced through the first digit and into the second digit without bending the implant or the first and second digits by rotating the digits at the first joint and the second joint.Type: ApplicationFiled: April 24, 2019Publication date: August 15, 2019Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventor: Koji J.

Publication number: 20190247189Abstract: 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: ApplicationFiled: April 23, 2019Publication date: August 15, 2019Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Theodore Paul Dale, Andrea N.

Publication number: 20190247191Abstract: A collapsible and expandable prosthetic heart valve stent is provided and comprising an outer section, a valve support defining a flow channel therethrough, a transition section configured to smoothly transition the outer section to the valve support. The valve support is disposed within an interior defined by the outer section, with the inflow end of the valve support disposed inside the outer section's interior. In some cases, the outflow end of the valve support is at least partially defined by the transition section. The prosthetic leaflets are disposed on the inner surface of the valve support's flow channel and are located at or above the annulus of the heart chamber. A paravalvular leakage mitigation system is attached to the stent to mitigate retrograde blood flow and/or regurgitation.Type: ApplicationFiled: February 11, 2019Publication date: August 15, 2019Inventors: Jeffrey W.

Publication number: 20190247192Abstract: A prosthetic mitral annuloplasty ring includes a wire, an adjustment member for changing a length of the wire and a jacketing annulus for adjusting a radial dimension of the mitral valve annuloplasty ring. The jacketing annulus is sleeved over the wire and forms, together with the adjustment member, a shape matching that of a native mitral valve annulus. After the prosthetic mitral annuloplasty ring is implanted by suturing in a conventional surgical procedure and the patient's heart starts to beat again, the adjustment member can be connected to the delivery device and the wire length therein can be adjusted by a rotating operation of the delivery device so that the mitral valve annuloplasty ring will be expanded or contracted until the prosthetic mitral annuloplasty ring perfectly fits the native mitral valve annulus in shape, effectively avoiding the problem of incomplete mitral leaflet coaptation.Type: ApplicationFiled: November 25, 2016Publication date: August 15, 2019Inventors: Qifeng YU, Lihong HOU, Zhijie WANG, Haishan WANG, Tao QIN
