  • Patent number: 10420662
    Abstract: Catheter including an inner tubular member, an outer tubular member movable relative to the inner tubular member, and a movable tubular structure coupled to the outer tubular member. A medical device disposed about a distal end portion of the inner tubular member. A proximal stopper is provided having a distal end and disposed proximal to a proximal end of the movable tubular structure. The distal end of the proximal stopper is spaced from the proximal end of the movable tubular structure at least a longitudinal length dimension of the medical device, wherein the outer tubular member and the movable tubular structure are movable in a proximal direction up to engagement of the proximal stopper to deploy the medical device from the inner tubular member.

  • Publication number: 20070191864
    Abstract: The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.
