  • Patent number: 9610076
    Abstract: A device is provided for closing a wound, such as a percutaneous access site. The device is inserted into the wound, and a helically shaped pusher is actuated to penetrate a wall of the wound. The pusher extends a suture through the tissue wall. After the suture is extending through the tissue wall, the pusher is retracted out of the tissue, while the suture remains extending through the tissue. The suture may then be used to close the wound.

  • Patent number: 9314358
    Abstract: A deployment device for repair of a transected body vessel is described herein. Device can have a handle and one or more shafts coupled thereto. A prosthesis being retained by a sheath can be coupled to the delivery device. The sheath can have end portions coupled to one or more shafts. Rotation of a shaft can retract a sheath portion away from either end of the prosthesis for expansion thereof prior to the middle of the prosthesis. Continued rotation of a shaft can completely remove the sheath from the prosthesis, so that the prosthesis is fully expanded and couples the first and second vessel portions of the transected vessel together. Prosthesis may be retained by overlapping a tubular sheath and lacing a threading member therethrough. Prosthesis may be retained by a splittable sheath.

  • Publication number: 20160074185
    Abstract: Medical device loading apparatuses, systems, methods and kits are described. A loading apparatus comprises a main body having a proximal end defining a proximal opening, a distal end defining a distal opening, and a passageway extending between the proximal and distal openings. The passageway defines a proximal chamber having a first inner diameter, a distal chamber having a second inner diameter, and a transition chamber disposed between the proximal and distal chambers. The transition chamber has an inner diameter that transitions from the larger second inner diameter to the smaller first inner diameter. The main body has a separable connection that divides the main body between proximal and distal portions when disrupted.

  • Patent number: 9271820
    Abstract: A filter device assembly and a method of using such a device to capture and remove embolic material from a body lumen or blood vessel are provided. The filter device assembly generally includes a structure having a collapsed state and an expanded state with first, second, and optionally N additional filter members circumferentially attached thereto. Each filter member forms an annulus chamber with the first filter member having porosity P1; the second filter member circumferentially having porosity P2; and the N additional filter members each having porosity [P3 . . . P(2+N)]. The magnitude of the porosity for the first, second, and N additional filter members follows the relationship P1>[P3>. . . >P(2+N)]>P2. The first, second, and N additional filter portions are configured in the expanded state to allow blood to flow there through and to capture emboli in the annulus chambers.

  • Patent number: 9220620
    Abstract: An endoluminal prosthesis introducer may include a rotatable inner cannula including a proximal end. The introducer may include a proximal tip disposed at the proximal end of the inner cannula and including a distal end. The introducer may include a retaining member including an engaging member extending radially outward. The retaining member may be disposed about the proximal end of the inner cannula. In response to rotation of the inner cannula with respect to the retaining member, the proximal tip may be longitudinally movable relative to the engaging member between a retaining configuration and a releasing configuration. The proximal tip and the engaging member may be spaced from one another by a greater longitudinal distance in the releasing configuration than in the retaining configuration.
