  • Publication number: 20140081387
    Abstract: Loading systems for compressing and loading an implantable medical device into a device chamber of a medical device delivery system are described. The loading systems include an elongate holding chamber within which the intraluminal medical device is disposed. A plunger has one or more attached pushers adapted to axially advance the intraluminal medical device through an intermediate portion of the holding chamber that has a tapered surface, which compresses the intraluminal medical device over a dilator of a medical device delivery system that has been introduced through the distal end of the elongate holding chamber. The elongate holding chamber can be placed within an outer storage container with an appropriate seal to for storage of the intraluminal medical device within the loading system. Methods of preparing an intraluminal medical device for implantation in a patient and kits useful in such methods are also described.

  • Publication number: 20140081315
    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 is provided. The filter device assembly generally comprises 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.

  • Publication number: 20140053415
    Abstract: A cutting tool is provided for cutting the end of a catheter to provide custom length catheters. The cutting tool has a cutting member that moves within the cutting passageway in the housing. The catheter is positioned within a catheter passageway in the housing. The cutting passageway transacts the catheter passageway so that a blade on the cutting member crosses the catheter passageway and cuts through the width of the catheter to form a cut end on the catheter.

  • Patent number: 8657866
    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.

  • Patent number: 8641753
    Abstract: An endoluminal prosthesis may include a tubular graft extending in a longitudinal direction, where the graft has an inner surface forming a lumen extending a length of the graft. An elongate member may be attached to the graft in a circumferentially and longitudinally extending manner such that the elongate member forms a series of longitudinally spaced apart turns, each turn extending substantially around a circumference of the graft. The elongate member may torsion the graft in at least the circumferential direction and cause the graft to form circumferentially and longitudinally extending folds in the portions of the graft disposed between longitudinally adjacent turns of the elongate member.
