Actively controllable heart valve implant and method of controlling same
A method of implanting a replacement mitral valve can include expanding a replacement mitral valve to a first expanded configuration. The replacement mitral valve can include a force-expanding mitral valve lattice and a self-expanding valve trampoline lattice. The mitral valve lattice has an inflow end portion and an outflow end portion, and the valve trampoline lattice is attached to the outflow end portion of the mitral valve lattice. The method can also include rotating a plurality of jack screws connected to the mitral valve lattice. The jack screws can be configured to expand the mitral valve lattice from the first expanded configuration to a second expanded configuration.
Prosthetic heart valve
A prosthetic heart valve can include a radially collapsible and expandable annular frame having a plurality of struts defining openings. The prosthetic heart valve can further include a plurality of leaflets that regulate the flow of blood through the frame. The prosthetic heart valve can also include a sealing member mounted on the frame and having an inner layer and an outer layer. At least the outer layer is mounted on the outside of the frame, and the inner layer covers at least the openings in the frame between adjacent cusp portions of adjacent leaflets and the inner layer does not cover one or more openings in the frame at locations facing the outflow surfaces of the leaflets to permit retrograde blood to flow through the one or more uncovered openings in the frame and into space between the outer layer and the frame.
Telescoping prosthetic valve and delivery system
An implantable device is disclosed. The device includes a two or three-piece frame assembly that is configured to be delivered in a series configuration and subsequently nested or telescoped in-situ.
Soft tissue retention devices, instrumentation and related methods
Soft tissue retention devices, instrumentation and related methods are disclosed. The devices include a first member comprising a first head portion and a first threaded shaft portion extending from the first head portion that define a cannulated opening extending therethrough, and a second member comprising a second head portion and a second threaded shaft portion extending from the second head portion that define a cannulated opening that extends therethrough. The inner sides of the first and second head portions includes a row of teeth extending about the periphery thereof. The first head portion also includes a plurality of through holes positioned between the first threaded shaft portion and the row of teeth. The outer sides of the first and second head portions include non-circular drive openings. The instrumentation comprise a handle portion with a through aperture that allows for a user's finger to extend therethrough during an implantation procedure.
DUAL-FLANGE PROSTHETIC VALVE FRAME
A method of replacing the function of a native heart valve is achieved by inserting a distal end portion of a delivery apparatus into a patient's body, wherein a prosthetic valve is disposed along the distal end portion of the delivery apparatus. The prosthetic valve includes a collapsible and expandable annular body having a network of struts interconnected at a plurality of nodes to form a plurality of open cells. Atrial and ventricular flanges are coupled to the annular body and extend radially away from the annular body. The annular body includes three commissure support posts of fixed length that extend substantially the entire length of the annular body. A valve member is secured to the commissure support posts. The annular body is radially expanded within the native heart valve and the atrial and ventricular flanges are deployed on opposite sides of the native heart valve.
METHODS AND DEVICES FOR THE TREATMENT OF PULMONARY DISORDERS WITH IMPLANTABLE VALVES
A flow control device (241, 260, 300, 350, 450, 480, 500) for a bronchial passageway including: a one-way valve (273, 313, 360, 478, 511); a hollow structural frame (242, 302, 352, 453, 468, 509) housing the one-way valve, wherein the structural frame is expandable from a collapsed configuration to an expanded configuration; and a sealing membrane (316, 470, 512) mounted to at least a distal portion of the structural frame, wherein the sealing membrane forms an enclosed wall defining at least a portion of an airflow passage through the flow control device, and the one-way valve is included in the airflow passage.
SHORT-THROW TISSUE ANCHOR DEPLOYMENT
A method comprises advancing an elongate tube to a target implantation site, the elongate tube having a needle disposed at least partially therein that has a coiled sutureform wrapped around at least a portion thereof, contacting a distal end of the elongate tube to a target tissue, projecting a tip of the needle from the distal end of the elongate tube to pierce through the target tissue such that the tip of the needle and at least a portion of the coiled sutureform project through the target tissue, advancing a pusher device within the elongate tube and over the needle to push the at least a portion of the coiled sutureform off of the tip of the needle, and proximally pulling one or more suture tails associated with the coiled sutureform to form the coiled sutureform into a knot on a distal side of the target tissue.
Replacement heart valve commissure assembly
A replacement heart valve commissure assembly may include a locking mechanism including a first locking portion spaced apart from a second locking portion in a delivery configuration and configured to engage with the second locking portion in a deployed configuration, wherein the first locking portion is longitudinally actuatable relative to the second locking portion between the delivery and deployed configurations. The commissure assembly may include a first valve leaflet and a second valve leaflet each secured to the first locking portion. A first sleeve portion of the first valve leaflet may be fixedly attached to a first fabric sleeve wrapped around a first leg of the first locking portion by a first filament, and a second sleeve portion of the second valve leaflet may be fixedly attached to a second fabric sleeve wrapped around a second leg of the first locking portion by a second filament.
Intervertebral Implant With Integrated Fixation
A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.
Stent and Securely-Installed Artificial Valve Replacement Device Having Same
A stent and a securely-installed artificial valve replacement device having the same, the stent being of a cylindrical structure; the top of the stent is provided with a fixed ear (60); the fixed ear (60) has a neck portion (601) connected to the top of the stent, and a head portion (602) engaged with the fixed head of the stent; the head portion (602) has a bending structure for improving the overall radial thickness; and the artificial valve replacement device is comprised of a stent and a prosthetic valve fixed on the stent. The stent with a bending structure overcomes the problem of easily disengaging from the fixed head of the stent, while not affecting the release of the stent.
