摘要： A loader and method for loading a transcatheter heart valve into a delivery sheath or catheter is described that is also configured to facilitate retrieval of the heart valve back through the delivery sheath while protecting the delivery sheath from damage. Another loader provides for easier crimping and loading of a THV into a delivery sheath or catheter from a storage jar or container. A method for crimping a THV facilitates easier end user preparation of the valve for implantation and reduces the likelihood of tissue deformation in the valve during storage. These devices and methods for deploying THVs simplify the valve replacement procedure.

摘要： Disclosed herein are catheter control handles that include various mechanisms for controlling the circumferential angle and radial magnitude of flexion of an attached catheter. Control handles can comprise a housing. Control wires extend from a distal end of the housing and into a steerable transluminal device. A flex control member is operable to control tension on the pull wires to adjust a magnitude of radial flexion of the steerable transluminal device. A position control member is operable to control tension on the pull wires to adjust a circumferential angle in which the radial flexion of the steerable transluminal device is directed.

摘要： A prosthetic implant delivery assembly includes a prosthetic implant and a catheter. The prosthetic implant includes a plurality of apices with apertures. Each apex of the plurality of apices is circumferentially-spaced apart relative to an adjacent apex. The catheter includes a plurality of arms and a plurality of locking elements. Each of the arms includes an opening configured to receive a respective apex of the prosthetic implant. Each of the locking elements is configured to extend through the aperture of a respective apex of the prosthetic implant. A length of at least one of the locking elements is different than a length of another locking element such that when the prosthetic implant is coupled to the catheter by the locking elements, a longitudinal axis of the prosthetic implant can be held at a tilted position relative to a longitudinal axis of the catheter.

摘要： An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. In some implementations, the implantable device or implant, or one or more portions thereof, can be configured to expand and/or contract. For example, the implantable device or implant can narrow during delivery and expand on implantation on the native heart valve.

摘要： In a particular embodiment, the present disclosure provides a prosthetic valve delivery assembly that includes a storage tube. A prosthetic valve having a frame is at least partially disposed within the storage tube. A nose cone is disposed about an elongated shaft. A stylet having at least a first bent portion extends through a lumen of the nose cone. The at least a first bent portion is disposed within the lumen of the nose cone and restricts axial movement of the elongated shaft relative to the prosthetic valve.

摘要： An exemplary valve repair device is released from tissue of a valve of a patient by applying tension to a movable arm of a clasp in a retraction direction. A fixed arm of the clasp is attached to an inner paddle portion of a paddle of the valve repair device. The inner paddle portion is connected to an outer paddle portion of the paddle of the valve repair device. Pulling the moveable arm of the clasp flexes the inner paddle portion to allow the moveable arm to move in the retraction direction and thereby release the clasp from the valve tissue.

摘要： A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.
