  • Patent number: 10405851
    Abstract: A laparoscopic suturing device is provided. The suturing device can pass a suturing needle back and forth between jaws of a jaw assembly to suture tissue at a surgical site in a minimally invasive procedure. The jaw assembly can have a pivotable jaw member in each jaw to position the jaw assembly and needle in a low-profile stowed configuration for insertion through a low diameter surgical port. The jaw assembly can be actuated by a handle assembly that provides simultaneous needle passing from a driving jaw to a receiving jaw and latching the needle within the receiving jaw in a single trigger cycle.

  • Patent number: 10405870
    Abstract: An apparatus and method for connecting two tubular vessels together in a side-by-side or tangential manner is disclosed. The apparatus has an annulus and at least one series of fingers connected to and extending away from the annulus. Each finger is preferably heat-formed into an arcuate shape. In use, a deployment apparatus is used to constrain the fingers of the apparatus to be in a relatively planar configuration. The deployment apparatus containing the apparatus is placed between and in contact with the two tubular vessels so that one tubular vessel is above the device and one tubular vessel is below the device and so that the fingers of the device come into contact with the tissue of the vessels. As the fingers penetrate the vessels the constraint on the fingers is removed so that the fingers can assume their unbiased, heat-formed arcuate shape. In this way, the fingers penetrate and grasp the tissue of the vessels so that the apparatus grasps the vessels and pulls the vessels toward each other.

  • Patent number: 10405880
    Abstract: A rotatable cutter for a tissue-removing catheter includes a central hub, flutes spaced apart from one another around the circumference of the central hub, and arcuate cutting members. Each cutting member includes an arcuate cutting edge extending along an arc length of the cutting member for cutting tissue as the cutter is rotated. A raised element of each cutting member has a leading cutting edge at a leading end of the distal cutting member for cutting tissue as the cutter is rotated. A clearance portion of each cutting member is recessed, relative to the longitudinal axis of the cutter, from the raised element and extends from the raised element to a trailing end of the cutting member to provide clearance for the leading cutting edge of an adjacent and opposing distal cutting member.

  • Patent number: 10363021
    Abstract: Vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. A combination of the body's own natural mechanism with chemical and/or biological agents is relied upon to accelerate the hemostatic process. Included are steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A sealing member disposed proximal the expansible member is then displaced by retracting and tensioning a coil spring so as to expose a chemical and/or biological region or release region of the device. The retraction and tensioning of the coil spring is limited by a coupling member. Exposure of blood and tissue to the chemical and/or biological sealing member promotes the clotting processing to accelerate the occlusion process in the tract.

  • Patent number: 10335301
    Abstract: A handle assembly for a prosthesis delivery device is disclosed. The handle assembly comprises a stationary main handle having a proximal end and a distal end and an outer surface extending therebetween. A first helical groove is formed in at least a portion of the outer surface of the main handle and a first trigger wire actuation mechanism disposed about the main handle and rotatably moveable relative to the main handle. A first trigger wire is operatively connected to the first trigger wire actuation mechanism, the first trigger wire having a prosthesis capture condition and a prosthesis release condition. Movement of the first trigger wire actuation mechanism causes movement of the first trigger wire thereby moving the first trigger wire from the prosthesis capture condition to the prosthesis release condition. Additional trigger wire actuation mechanisms operatively connected to one or more additional trigger wires may also be disposed about the main handle.

  • Patent number: 10016201
    Abstract: A vascular plug has a frame or skeleton which includes a ring of spring material and, attached to the frame, a cover of impervious or porous material. The plug is able to open a cup configuration when in a deployed condition, so as to provide an occlusion barrier to blood flow. The frame can be radially contracted by twisting into a multi-coiled configuration for deployment through an introducer. The vascular plug has a very short deployment length, making it suitable for deployment in precise locations and is also able to expand to a variety of operating diameters, thereby being suitable for a range of vessel sizes.

  • Patent number: 8012193
    Abstract: An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (22) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

  • Patent number: 7981139
    Abstract: The present invention provides apparatuses, systems, methods and kits for fastening sutures or similar devices used in medical surgical procedures. In particular, the present invention is suitable for use with percutaneous or minimally invasive procedures in which sutures are placed with catheter-based devices wherein the tying of knots is particularly challenging. Suture fasteners of the present invention provide for fastening the sutures together in a fixed position at any location along the suture strands. In addition, the fasteners are adjustable to allow repositioning of the fastener after placement to a new desired location along the suture strands. Similarly, such fasteners may be used to hold a single suture strand for various applications.
