METHODS OF RAPIDLY DEPLOYABLE SURGICAL HEART VALVES

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

CATHETER WITH INTEGRATED EMBOLIC PROTECTION DEVICE

A prosthetic heart valve delivery catheter includes an embolic filter to provide integrated embolic protection to inhibit the release of emboli into the aorta, the aortic arch or branch vessels, and other vasculature during transvascular heart valve replacement procedures. The embolic filter will usually be fixedly or movably attached to a shaft of the delivery catheter proximal of the prosthetic heart valve.

Stent

Provided is a stent which is not easily displaced from a dwell site in a biological lumen and which has an excellent ability to follow a biological lumen. This stent (bile duct stent 100) is to dwell inside a biological lumen (bile duct B) and is provided with a stent main body section (110) having a cylindrical shape. The stent main body section is configured to be capable of expanding and contracting in the radial direction that is approximately orthogonal to an axial direction, has a relatively large expanding force in one portion (center portion) corresponding to the predetermined position at the indwelling site in the biological lumen, and a relatively small expanding force at other portions (both end portions) which have different positions in the axial direction from that of the one portion.

Resilient arthroplasty device
09808345 · 2017-11-07 · ·

The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.

Bodily implant with tension indicator

A bodily implant is provided to support body tissues of a patient. The bodily implant includes a strip having a first portion and a second portion. The strip is configured to be stretched in a manner such that the second portion is stretched from a first length to a second length. The second portion of the strip is configured to maintain the second length. The strip is further configured to be disposed proximate to the patient's body tissues.

Method and apparatus for creating a reconstructive graft

A method and apparatus is provided for creating an internal reconstruction tissue graft. Templates may be used to create a multitude of patterns in a variety of tissue reconstruction grafts. An apparatus may be used to create an internal tissue graft for reconstruction through either compression and/or removal of segments. An apparatus may be used, through either compression and or removal of segments of a preformed template made of synthetics and or metal that mirrors a template that can be used as an internal tissue graft for reconstruction. In a method, such as using software analysis and an apparatus, the physical properties of the tissue graft and its pre- and post-operative properties and appearance may be measured.

TRANSCATHETER VALVE REPAIR HAVING IMPROVED PARAVALVULAR SEAL
20210401599 · 2021-12-30 ·

A heart valve assembly includes an inner frame comprising a graft covering housing a prosthetic heart valve, wherein the graft covering extends around the prosthetic heart valve for providing sealing to the heart valve, an outer frame formed from a metallic material and defining a gridded configuration, and being secured to the graft covering by a plurality of stitches, and a sealing material positioned externally to the outer frame for providing sealing between the outer frame and a patient's anatomical wall to prevent paravalvular leaks. The sealing material includes a plurality of radially extending fibers that extend outwardly of the outer frame. The graft covering is made of polyester, polytetrafluoroethylene, expanded polytetrafluoroethylene, or a polymer.

Methods and devices for heart valve repair

A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaption of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.

METHODS AND DEVICES FOR TREATING ILIOCAVAL COMPRESSION, OCCLUSION, REDUCTION OF VENOUS CALIBER, AND SYNDROMES AND DISEASE STATES RESULTING FROM OCCLUSION

Aspects of the invention provide a self-expanding stent device. The device comprises: an elongated body that defines a lumen within. The body has a first and a second terminus and a longitudinal axis located therebetween. The body comprises a first zone and a second zone along the longitudinal axis. When the device is in an expanded configuration the first zone has a first radial strength that is resistant to an external compressive force, and the second zone has a second radial strength that is resistant to an external compressive force. The radial strength of the first zone is greater than that of the second zone. The diameter of the body lumen proximal to the first terminus is greater than that of the lumen proximal to the second terminus.

ENDOVASCULAR PROSTHETIC HEART VALVE REPLACEMENT
20220183830 · 2022-06-16 ·

A prosthetic aortic valve intended for native or valve-in-valve within bioprostheses includes an expandable support scaffold and valve leaflets disposed within an upper leaflet portion of the support scaffold. The valve leaflets within the upper portion may be located within the annulus (intravalvular), above the annulus, or above the native or prosthetic leaflets (supravalvular). The valve within a previously implanted degenerated heart valve such that a base or lower portion of the replacement valve is within the previously implanted valve and the upper portion is expanded within the aorta, the internal area of the valve can be increased and the hemodynamics of the valve improved. Alternatively, the valve may include separate upper and lower portions allowing the portions to be implanted sequentially and the length and other characteristics of the valve to be adjusted based on patient anatomy and condition.
