    Abstract: A transcatheter valve prosthesis includes a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes at least one axial frame member. The transcatheter valve prosthesis includes at least one outflow marker positioned on the at least one axial frame member. The transcatheter heart valve prosthesis may include inflow markers positioned within the inflow portion of the stent. The transcatheter heart valve prosthesis may include two outflow markers disposed on axial frame members, the two outflow markers being circumferentially and longitudinally offset from each other. The markers are configured to aid in axial and circumferential alignment of the transcatheter heart valve prosthesis within a native heart valve.

    Abstract: Methods for purging a balloon catheter of air. An inflation fluid is inserted into a balloon and an inflation lumen of a balloon catheter. The inflation lumen is in fluid communication with the balloon. The balloon catheter is positioned in an inverted orientation with a distal end thereof disposed below a proximal end thereof. The distal end of the balloon catheter includes a balloon. A vibration source is positioned in direct contact with an outer surface of the balloon catheter. The balloon catheter is vibrated via the vibration source. A vacuum is applied or pulled on the inflation lumen of the balloon catheter. The steps of vibrating the balloon catheter and applying the vacuum are performed simultaneously.

    IPC: A61F2/95

    Abstract: A crimper for altering an implantable medical device from an uncompressed state to a compressed state. The crimper includes a plurality of crimper elements that define a crimper channel, each of the crimper elements including a non-planar surface that forms a portion of the crimper channel. Each non-planar surface is configured to apply non-uniform radial compression along a length of the implantable medical device during operation of the crimper when altering the implantable medical device from the uncompressed state to the compressed state. The crimper also includes handle configured to operate the crimper. Actuation of the handle decreases a volume of the crimper chamber to transition the implantable medical device from the uncompressed state to the compressed state.

    Abstract: A catheter includes a handle with torqueing and steering mechanisms. The torqueing mechanism includes a rotatable nosecone and a bearing coupled to the nosecone to be rotatable therewith. The bearing is concentrically disposed over a shaft of the catheter. The steering mechanism includes a rack coupled to the bearing to be slideable therewith and a pull wire having a proximal end attached to the bearing and a distal end attached to a distal portion of the shaft. Rotation of the nosecone causes an entire length of the shaft to rotate and axial movement of the rack tensions the pull wire to bend the distal portion of the shaft. A valve relief component is slidingly disposed over the shaft and is configured to dock onto the handle when not in use.
