  • Publication number: 20140277347
    Abstract: The present disclosure includes an endoprosthesis comprising a tube or substantially tubular lumen. The tube can comprise a first end and a second end, and a side wall can extend between the first and second ends. The side wall can be fenestrated by a side opening or fenestrated portion. The endoprosthetic device can further comprise a patch or support wall coupled to an inner surface of the side wall. The patch can overlap the fenestration. Further, the patch can have a first open edge and/or a second open edge, both of which can open to receive a branch endoprosthetic device. The patch can be movable between a closed configuration adjacent to the inner surface of the side wall and an open configuration spaced apart from the inner surface of the side wall. The open configuration can define a support channel that receives the branch endoprosthetic device.

  • Patent number: 8679137
    Abstract: A buttress for use with circular surgical staplers that does not require adhesive to securely fasten the buttress to the stapler. Following cutting and stapling by the circular stapler, the buttress has an adaptive opening through its central region with a diameter smaller than the outer diameter of the stapler anvil. Because of relief features built into the buttress, the stapler anvil may be pulled through the buttress material without causing permanent alteration to the buttress. These relief features may be provided regardless of whether the buttress is made of inelastic or elastic materials. The buttress is generally circular in shape with an outer diameter sized to coincide with the outer diameter of the stapler body staple compression surface and the outer diameter of the anvil compression surface of a circular stapler with which it is used. Prior to surgical use, the buttress is attached to the stapler with disruptable portions extending from outer perimetal areas of the buttress.

  • Publication number: 20140067038
    Abstract: In accordance with various embodiments, an anchoring system for a medical device comprises one or more biased hooks. The one or more biased hooks may be formed by any suitable process. Moreover, the one or more biased hooks may be formed from a shape memory material. The anchoring system may be processed in any suitable way to provide a designed or predefined failure mode. This failure mode may be designed to protect or prevent damage to the medical device. The anchoring system may be configured with a plurality of hooks biased in various directions. Moreover, the anchoring system may be configured with a plurality of substantially small hooks configured to engage the anatomy at multiple points. As such, the anchoring systems may be customizable and provide for an implantable medical device with a reduced delivery geometry and/or deployment geometry.

  • Publication number: 20110087318
    Abstract: The present invention comprises a highly conformable stent graft with an optional portal for a side branch device. Said stent graft comprises a graft being supported by a stent, wherein said stent comprises undulations each which comprise apices in opposing first and second directions and a tape member attached to said stent and to said graft such that the tape member edge is aligned to the edge of the apices in the first direction of the each of the undulations, thus confining the apices in the first direction of the undulations to the graft and wherein the apices in the second direction of the undulation are not confined relative to the graft; wherein said graft forms unidirectional pleats where longitudinally compressed and wherein said apices in the first direction of said undulation is positioned under an adjacent pleat when compressed. The invention also discloses and claims methods of making and using said highly conformable stent graft and method of making the optional portal.

  • Publication number: 20040143240
    Abstract: A catheter provided with an adjustable length guidewire catheter lumen, located proximal of a therapeutic device or agent positioned at the distal end of the catheter. The length of the adjustable length guidewire catheter lumen is controlled by the physician, allowing the benefits of both over-the-wire and rapid exchange systems to be provided in one catheter. The adjustable length is provided with a thin-walled tube that corrugates under axial compression. The tube may optionally be pre-corrugated or may be allowed to corrugate non-uniformly under the axial compression. The catheter length may change by, for example, over 100% of its original length between full axial compression and full axial extension.

  • Patent number: 5758664
    Abstract: A method of making a left ventricular assist device (LVAD) using muscle wrapped around a mandrel to form a muscle pouch, the open end of which is sewn to a circular sheet of patch material having connections to one end of each of a pair of vascular grafts, or alternatively to one end of a single vascular graft. The second ends of these vascular grafts are used to connect the LVAD to the aorta. After the muscle pouch has been formed around the mandrel, the mandrel is removed and replaced by a balloon which is inserted into the muscle pouch and inflated to maintain the desired shape of the muscle pouch during healing and stimulation of the pouch. The balloon is subsequently removed preceding activation of the LVAD to allow it to begin pumping blood. Alternatively, various other shape-maintaining forms which are expandable and collapsible may be used in place of the balloon.

In an alternative embodiment, an additional strip of latissimus dorsi or other appropriate muscle or a mechanical clamping device may be used to synchronously compress the aorta between the ends of the vascular grafts anastomosed to the aorta.
