  • Patent number: 8961541
    Abstract: A tissue closure system can include a deployment instrument and a sealing element. The deployment instrument can be slidably mounted to and guided by a tubular medical device. The deployment instrument can be advanced over the tubular medical device to the desired location. The sealing element can then be advanced off of the end of the tool. The sealing element can include tissue engaging elements that are configured to automatically close upon deployment to bring together tissue. A slidably attached guided skin (or other tissue) cutter can also be used if desired to facilitate entry of the deployment instrument.

  • Patent number: 8940017
    Abstract: A hernia repair implant includes a first layer for facing a body structure having a hernia defect to cover the defect while promoting tissue growth into the first layer from the body structure. The implant also includes a second layer opposed to the first layer and made of anti-adhesion material to prevent growth of tissue into the second layer from body structures contacting the second layer. Furthermore, the implant includes at least one engagement strap connected to the first layer and extending therefrom to terminate at a free end. The engagement strap defines opposed thin edges and opposed flat surfaces extending between the edges. At least one barb extends from at least one edge and/or at least one flat surface of the strap and is configured to impede motion of the strap in only a single direction.

  • Patent number: 8926636
    Abstract: In some embodiments, an apparatus includes a handle and an elongate member coupled to the handle. The elongate member has a first portion, a second portion and a third portion. The first portion of the elongate member extends from the handle and defines a first longitudinal axis. The second portion of the elongate member extends from the first portion and defines a second longitudinal axis. The first longitudinal axis and the second longitudinal axis define a first angle and a first plane. The third portion of the elongate member extends from the second portion of the elongate member and defines a third longitudinal axis. The third longitudinal axis and the second longitudinal axis define a second angle and a second plane. The second plane is non-parallel with the first plane.

  • Patent number: 8920487
    Abstract: An intravascular stent especially suited for implanting in curved arterial portion. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The cells are adapted to provide radial support, and also provide longitudinal flexibility after expansion. The cells also provide increase coverage of a vessel wall. Loops in the stent are disposed and adapted to cooperate, so that after expansion of said stent within a curved lumen, the stent is curved and cells on the outside of the curve open in length, but narrow in width, whereas cells on the inside of the curve shorten in length, but thicken in width to maintain a density of the stent element area which is much more constant than otherwise between the inside and outside of the curve. The stent also minimizes flaring out by eliminating free loops of the radially supporting circumferential bands of loops.

  • Patent number: 8911491
    Abstract: A stent graft extends in a flow lumen to span a defective portion of the flow lumen and seal the defective portion from further blood contact. The stent graft includes a pair of apertures, from which extensions project into the renal arteries to seal the passage of blood into the renal arteries from the abnormality. The apertures are larger than the opening of the renal arteries, such that the apertures need not be centered with the renal arteries to enable placement of the extensions. The aperture opening and side branch extensions contain hook and loop structures to provide a variably positionable seal of the aperture opening.

  • Patent number: 8911474
    Abstract: An apparatus for inserting a suture anchor into an internal anatomical site through a cannula, or percutaneously, has a curved hollow guide for insertion into the cannula and/or tissue. The guide has a proximal end and a distal end. The distal end has a “parabolic” shape for engaging the intended anatomical site such as a glenoid. A flexible obturator is insertable through the curved guide from the proximal end to the distal end to facilitate insertion of the guide through the cannula. A flexible drill is insertable through the curved guide from the proximal to the distal end once the guide is in place. A flexible inserter is provided for inserting a suture anchor into a bore at the anatomical site formed by the flexible drill.

  • Patent number: 8911489
    Abstract: A medical implant (20) includes first and second ring members (22, 24), each including a resilient framework (26) having a generally cylindrical form. A tubular sleeve (28) is fixed to the first and second ring members so as to hold the ring members in mutual longitudinal alignment, thereby defining a lumen (32) passing through the ring members. A constricting element (30) is fit around the sleeve at a location intermediate the first and second ring members so as to reduce a diameter of the lumen at the location.

  • Patent number: 8911458
    Abstract: Herein is provided an anastomosis device which includes a cylindrical support housing having a tapered section being formed of a plurality of compliant fingers integrally formed around the circumference of an end of the cylindrical section which can flex at their connection point to the cylindrical section. Each compliant finger holds a suture needle. The device includes a push rod having a cam head at one end of the rod section. The cam head is located adjacent to the tapered portion. In operation the anastomosis device is aligned with the anatomical tubular structure undergoing an anastomosis process. When a back end of the push rod is pushed towards the tapered section of the support housing, the cam head section bears against an inner surface causing each compliant finger to flex radially outwards forcing the suture needles to simultaneously pierce the wall of the anatomical tubular structure.

  • Patent number: 8876893
    Abstract: A delivery device for percutaneously deploying a prosthetic valve includes a sheath, an inner shaft, and a release assembly. The release assembly is disposed between the sheath and the inner shaft, and includes a retraction member, a release member, and a retention member. The retraction member can self-retract in length from an extended condition to a retracted condition. The release member can self-expand from a compressed condition to an expanded condition. The retention member is distal the release member. In a delivery state, the sheath end is distal the retention member, the release member is in the compressed condition and the retraction member in the extended condition to retain the prosthesis. In a deployment state, the sheath end is positioned to permit the release member to self-transition to the expanded condition, allowing the retraction member to self-transition to the retracted condition and release the prosthesis.

  • Patent number: 8876852
    Abstract: In at least one embodiment of the present invention, a method for making an occluding device for occlusion of fluid flow through a lumen of a body vessel is provided. The method comprises attaching a coating to an embolization coil that is substantially straight. The coating is nominally strained on the substantially straight embolization coil. The embolization coil has a pre-curled tension to facilitate the embolization coil being curled within the lumen of the body vessel when deployed. The embolization coil is restrained from curling until deploying to reduce pre-deployment straining of the coating.
