System and method for increasing a cross-sectional area of a body lumen

Devices and methods are disclosed for managing and/or treating body tissues obstructing a hollow body lumen, such as the prostatic lobe tissues obstructing the urethra. A scaffolding may be provided with opposing tissue-engaging portions and at least one expansion member configured to transition between a compressed configuration having a reduced distance between the tissue-engaging portions and a deployed configuration having an increased distance between the tissue-engaging portions.

METHOD AND DEVICE FOR MITRAL REPAIR INCLUDING PAPILLARY MUSCLE RELOCATION

A delivery catheter as disclosed herein may be configured in various embodiments to minimize the potential for entanglement between cardiac repair components such as between sutures and coupled anchors. In various embodiments this is achieved by separating an anchor translation channel from a suture translation channel while maintaining the coupling between the anchor and the suture.

STENT AND ASSOCIATED SYSTEMS AND METHODS

A mesh element having a mesh gauge selected to control flow of materials therethrough. The mesh element is implantable into an anatomical structure upstream of a body passage or within a body passage to control flow of materials through the body passage. The mesh element may be coupled to a support structure to facilitate anchoring of the mesh element in place relative to the body passage. The support structure may have a lumen defined therethrough to allow flow of materials through the body passage, with the mesh element regulating the flow of materials into the lumen. The mesh element alternatively may be directly coupled to an anatomical structure upstream of a body passage to regulate or determine flow of materials through the body passage.

Low profile ribbon frame for valve repair devices

A low profile implant, system and method of deployment includes a frame comprising an elongate body having ends that overlap to form an annular configuration of the frame. A circumference of the frame may be modified by varying an extent of the overlap between the ends of the elongate body. The elongate structure may extend through a sleeve of a number of respective anchor housings of the implant along a first axis, and anchors may be deployed through bores in the anchor housings along a second axis to secure the anchor housings to tissue. The implant may be deployed about and anchored to a valve annulus, and the circumference of the frame, and associated anchored tissue, may be adjusted to reconfigure the valve annulus.

TRANSCATHETER DELIVERABLE PROSTHETIC HEART VALVES AND METHODS OF DELIVERY

A prosthetic valve includes a frame and a flow control component. The frame has an aperture extending through the frame about a central axis. The flow control component is mounted within the aperture and is configured to permit blood flow in a first direction approximately parallel to the vertical axis from an inflow end to an outflow end of the flow control component and to block blood flow in a second direction, opposite the first direction. The frame has an expanded configuration with a first height along the central axis, a first lateral width along a lateral axis perpendicular to the central axis, and a first longitudinal length along a longitudinal axis perpendicular to the central axis and the lateral axis. The frame has a compressed configuration with a second height less than the first height and a second lateral width less than the first lateral width.

DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION

Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve and an edge to edge device. Methods are disclose for reducing mitral valve regurgitation at low left ventricle pressure and high left ventricle pressure during the cardiac cycle. Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve with an adaptive coaptation element.

Stented heart valve devices and methods for atrioventricular valve replacement

A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with a tapered edge.

Prosthetic valves and methods of use of prosthetic valves may be provided. In one implementation, a prosthetic valve may include an annular outer frame, an inner frame, and a plurality of ventricular anchoring legs extending from the outer frame. The outer frame may be formed at least partially of struts intersecting at junctions. At least one ventricular anchoring leg may include a first curved leg portion on a first surface of the leg, and a second curved leg portion on a second, opposite surface of the leg. The outer frame may also include a strut extending between a downstream end of the outer frame and the junction from which the at least one ventricular anchoring leg extends.

Stabilizing and adjusting tool for controlling a minimally invasive mitral / tricuspid valve repair system

Disclosed herein are embodiments related to a method for performing a minimally invasive procedure, the method including delivering an annuloplasty ring in a linear shape using a delivery system. In some embodiments, the delivery of the annuloplasty ring may utilize a trans-septal approach or a trans-apical. In some embodiments, the delivery system may position the annuloplasty ring using a flexible stabilizing mechanism and/or activate one or more anchors to extend outward from the annuloplasty ring.

20220401241 · 2022-12-22 ·

A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.
