  • Patent number: 10639181
    Abstract: A system for delivering an implant including a handle, a trigger, an actuation assembly, and a catheter assembly. The actuation assembly is configured to displace the outer tubular member in the proximal direction and to separately move the inner shaft member distally upon deployment of the trigger from the first position to the second position, and move the inner shaft member proximally with no displacement of the outer tubular member upon return of the trigger from the second position to the first position. The catheter assembly includes an outer tubular member, an inner shaft member, and a pusher assembly.

  • Publication number: 20180193605
    Abstract: Catheter assembly for delivering an implant including an outer tubular member, an inner shaft member, and a pusher assembly. The outer tubular member defines an outer tubular member lumen and includes an inner layer, a reinforcement layer, a middle layer, and an outer layer. The inner shaft member is disposed at least partially within the outer tubular member lumen. The inner shaft member includes a proximal inner shaft portion and a distal inner shaft portion, the distal inner shaft portion having a distal end portion. The pusher assembly is coupled to the distal end portion of the distal inner shaft portion. The inner shaft member is configured to move distally and proximally relative the outer tubular member between an initial position and a deployed position.

  • Patent number: 8182463
    Abstract: A delivery catheter that includes a flexible shaft having a proximal end and a distal end, the distal end having an outer diameter less than about 13 mm; a delivery lumen having a proximal end and a distal end, the delivery lumen within the flexible shaft, the delivery lumen having at least an outlet port or at least one side hole at the distal end of the delivery lumen, the delivery lumen having a cross-sectional area at least about 5 mm2; a pressure monitoring lumen having a proximal end and a distal end, the pressure monitoring lumen within the flexible shaft; a pressure port adjacent to and connected to the distal end of the pressure monitoring lumen; a balloon inflation lumen having a proximal end and a distal end, the balloon inflation lumen within the flexible shaft; a soft tip at the distal end of the flexible shaft; a balloon at the distal end of the flexible shaft, the balloon connected to the distal end of the balloon inflation lumen, the balloon includes at least one of the following materials, po

  • Publication number: 20080140003
    Abstract: A method of using a balloon catheter to perform a medical procedure at a treatment site in a patient's body lumen and to recover an expanded device, such as an embolic protection device, which is adjacent to the treatment site in the body lumen. The inflated balloon is deflated and regroomed to a low profile configuration in the body lumen, and the balloon catheter is advanced distally from the treatment site to collapse the expanded device (e.g., embolic protection filter) within the balloon catheter. The balloon catheter has a recovery distal tip for collapsing an expanded device, and has a regrooming sheath member configured to slidably receive the deflated balloon therein to regroom the balloon.
