Publication number: 20230390058Abstract: Devices and methods for retrieving percutaneously implanted catheter systems such as a heart valve repair system. The devices include at least one locking connector at the distal end of a flexible elongated extension for coupling to an implanted tubular member. The locking connector may be a tubular anchor having a pair of distal prongs which are biased outward and face in a proximal direction, as well as an expandable auxetic midsection. Inserting the tubular anchor into the implanted tubular member flexes the distal prongs inward such that they prevent proximal movement of the tubular anchor. A user pulls on the proximal end of the tubular anchor to expand the auxetic midsection and lock the two pieces together. The devices and methods are particularly useful to attach extensions to implanted concentric tubes to enable relative axial force application.Type: ApplicationFiled: August 8, 2023Publication date: December 7, 2023Inventors: Joseph Arthur Passman, Omar Fawzi Azanki

Publication number: 20230320853Abstract: A system for delivering medical implants has an expandable introducer sheath which can locally expand and lengthen to accommodate passage of a delivery catheter and implant, such as a prosthetic heart valve secured to a balloon catheter. The expandable sheath may be configured so that the local expansion is proportional to the local surface lengthening.Type: ApplicationFiled: May 10, 2023Publication date: October 12, 2023Inventor: Joseph Arthur Passman

Publication number: 20220008201Abstract: Devices for anchoring catheter systems, such as an atrioventricular heart valve regurgitation reduction system with a coapting element or spacer positioned within the atrioventricular valve leaflets. The spacer may be anchored above the atrioventricular valve with a rail that extends up into the subclavian vein, with tethers that attach to anchors around the annulus, or with a tether that connects to a stent expanded within an adjacent blood flow passage. The spacer may also be anchored below the atrioventricular valve with a rail that terminates in a tissue anchor within the ventricle, with tethers that attach to anchors around ventricle, or with a tether that connects to a stent expanded within an adjacent blood flow passage. The spacer may also be stabilized by a harness extending across the valve annulus or may be self-anchoring with an array of struts that extend into contact with the surrounding tissue.Type: ApplicationFiled: September 22, 2021Publication date: January 13, 2022Applicant: Edwards Lifesciences CorporationInventors: Joseph Arthur Passman, Rohan Yogee Katbamna, Minh T.

Patent number: 11116629Abstract: A delivery apparatus for implanting a prosthetic implant in a native lumen of the body includes a handle portion, and a first shaft extending from and movable relative to the handle portion. The first shaft has a proximal end portion coupled to the handle portion and a distal end portion. The delivery apparatus further includes a second shaft extending from the handle portion and coaxially disposed within the first shaft. The second shaft has a proximal end portion coupled to the handle portion and a distal end portion configured to mount a prosthetic implant in a radially compressed state. The handle portion of the delivery apparatus also includes a steering assembly configured to move the first shaft longitudinally relative to the second shaft while concurrently flexing the second shaft.Type: GrantFiled: December 30, 2019Date of Patent: September 14, 2021Assignee: Edwards Lifesciences CorporationInventors: Joseph Arthur Passman, Linda Thai, Michael C.

Patent number: 11007061Abstract: Devices and methods for treating patients with functional tricuspid regurgitation (TR) who are unsuitable for surgery include an interoperative, adjustable-size coapting element on a catheter which may be implanted within the left or right side of the heart and extends upward into the vasculature and out of the body. The radial diameter of the coapting element can be modulated in tandem with electrocardiographic imaging to reduce valve regurgitation. One system has an elongated catheter and an expandable coapting element mounted to a distal end with an auxetic structure connected to opposite end caps. A tensioning mechanism controlled from a proximal end of the catheter is configured to pull apart the two end caps and thus elongate and radially expand the auxetic structure. Other forms of the coapting element are disclosed, as well as a kink-resistant catheter sheath having a triangular cross-section.Type: GrantFiled: May 14, 2019Date of Patent: May 18, 2021Assignee: Edwards Lifesciences CorporationInventors: Joseph Arthur Passman, Omar Fawzi Azanki, Kokou Anani Amefia
