  • Patent number: 9855159
    Abstract: A stent includes a wavy-shaped member extending circumferentially, and expandable and contractable in the radial direction of the stent. The wavy-shaped member includes a pair of straight parts, an apex part and an opening. The ends of the apex part are connected to the straight parts. The opening is positioned at least in the apex part. The apex part has a link part at the outer circumference side of the opening, and a base part at the inner circumference side of the opening. The base part has a curved inner circumference and the link part lies across a vertex of the base part. The width of the link part in relation to the circumferential direction of the stent is smaller than the width of the base part in relation to the circumferential direction of the stent, at the vertex of the base part.

  • Patent number: 9801621
    Abstract: Techniques and reconstruction systems for soft tissue surgical repairs. The biceps tenodesis technique of the present invention provides fixation of a single diameter of the biceps tendon in a socket without the need for externalizing the tendon and without the need to pass any suture (or similar material) through any portion of the tendon (i.e., without the need to stitch or whipstitch any area/portion of the tendon). The technique improves the biomechanics of the combined fixation and helps overcome surgeons' concerns about rapid return to ADLs.

  • Patent number: 9795386
    Abstract: A multiple band endoscopic ligation device comprises a single pull string and a plurality of beads positioned on said pull string and between each successive band. The device is configured to be coupled to the distal end of an endoscope and is used to deploy multiple elastic bands around target tissues to be ligated. The device includes a tapered cylindrical body about which a plurality of elastic bands are stretched and positioned. The pull string includes multiple sets of two beads fixed to the string wherein one bead is placed directly behind and in contact with the other. The string is wrapped around the device's body and under each band such that at least one pair of beads is positioned between the elastic bands and one pair of beads is positioned proximally to the most proximal band. As the string is pulled, the beads push the bands sequentially off the distal end of the device and around a tissue to be ligated.

  • Patent number: 9782182
    Abstract: An abdominal aortic tourniquet having one-piece member for the bladder and cover portions and whose bladder has a triangular cross-sectional shape when inflated that significantly increases the amount of point pressure such that the intended artery is properly occluded. The one-piece bladder/cover design provides for a reduction in cost of materials and provides for a more compact piece as compared to prior designs. The abdominal aortic tourniquet uses a single piece of weldable and gas impermeable fabric that is configured in a novel manner to create a three-dimensional, pneumatic piston while also serving as storage/transport cover, attachment structure, and major component of the belt member.

  • Patent number: 9675405
    Abstract: Methods and devices for controlling motorized surgical devices are provided. In general, the methods and devices can allow a surgical device to grasp and cut tissue. In some embodiments, the device can include at least one sensor and a motor, and an output of the motor can be configured to be adjusted based at least in part on an output from the at least one sensor. The output of the motor can be configured to provide power for translation of a cutting element along an end effector of the device. Adjusting the motor's output can cause the cutting element to translate through the end effector at different speeds, thereby allowing the cutting element to cut through tissue being grasped by the end effector at different speeds.

  • Patent number: 9662236
    Abstract: A stent delivery system wherein, in a gap between an inner tube body and an outer tube body, a sealing member is arranged on the proximal side relative to a distal opening of a lumen, which extends from the proximal end of the inner tube body, and a guide wire leading-out hole. The inner circumferential surface of the sealing member is fixed to the outer circumferential surface of a first proximal tube of the inner tube body, and the outer circumferential surface of the sealing member is in sliding contact with the inner circumferential surface of a second proximal tube of the outer tube body. When blood or the like enters into the stent delivery system via the distal ends of the inner tube body and the outer tube body, progress of the blood or the like toward an operating unit side is inhibited by the sealing member.

  • Patent number: 9629650
    Abstract: A laparoscopy tool includes a sheath and a control wire slideably disposed within a lumen of the sheath. The sheath has a diameter of less than 1.6 mm and is introduced through an abdominal incision. A handle axially displaces the control wire within the lumen and operates a conventional tip with wire-controlled opposing jaws that is introduced through the umbilicus and has a bore formed in its trailing end. A first set of blades in the bore engage grooves formed in the leading end of the control wire and a second set of blades engages the sheath to prevent sheath retraction. A cam displaces the second set of blades away from the sheath for sheath introduction and removal, and toward the sheath to prevent sheath retraction. The tip is removed through the umbilicus and the tool is removed through the abdominal incision when the surgery is completed.
