  • Patent number: 8940016
    Abstract: A mechanical system for rotatably, sequentially securing opposing sides of a tissue wound with a fastener. An applicator apparatus is capable of imparting rotatable motion to a falcate tissue penetrator that sequentially pierces and carries a fastener into a first side and a second side of the tissue wound. The first side and second side of tissue can be simultaneously captured and positioned with respect to a tissue definition member or alternatively, the first tissue side and second tissue side can be individually, sequentially captured and positioned relative to the tissue definition member. The applicator apparatus can comprise a single fastener for small tissue wounds or resections or alternatively, the applicator can comprise a plurality of staged fasteners for use in closing a larger wounds or wounds with increased tension.

  • Patent number: 8906047
    Abstract: The present invention relates to a resorbable polymeric mesh implant, that is intended to be used in the reconstruction of soft tissue defects. The mesh implant comprises at least a first and a second material, wherein the second material is substantially degraded at a later point in time than the first material following the time of implantation. The mesh implant is adapted to have a predetermined modulus of elasticity that gradually is decreased until the mesh implant is completely degraded and subsequently resorbed. Due to the gradual decrease in the modulus of elasticity of the inventive mesh implant, the regenerating tissue may gradually take over the load applied to the tissue defect area.

  • Patent number: 8882785
    Abstract: An endoscopic suturing device that can be employed to suture tissue using endoscopic techniques to place one or more stitches in tissue during a single intubation of an endoscope. The suturing device may include a suturing capsule with a suction chamber that is configured to capture tissue that is to be sutured. A needle is movable along a pathway across the suction chamber to penetrate and place stitches in the captured tissue. A catch is located distal to the suction chamber to receive and retain the suture during a stitching sequence. The catch may be movable along the needle pathway and configured to release the suture when the catch moves a predetermined distance along the pathway. The catch may be configured so that a predetermined amount of force is required to move the catch the predetermined distance required to release the suture.

  • Patent number: 8834521
    Abstract: A surgical construct having a flexible strand with a middle region and at least two opposing tail regions that are spliced to form a single tail. The middle region has a first diameter and the opposing tail regions have a second diameter, which is smaller than the first diameter. The tail regions may have similar or different diameters. Because of the thin spliced tail regions, the suturing construct of the present invention can be easily inserted into suture/tape passing and retrieving instruments and passed through soft tissue (such as a rotator cuff). Once the suturing construct has been passed through tissue, the splice may be cut to allow the suture/tape to have again individual tails.

  • Patent number: 8795384
    Abstract: An implantable tissue reinforcement device useful for treating or preventing the formation of parastomal hernias forming about a surgically created stoma. The tissue reinforcement device can comprise a synthetic or mammalian-derived sheet-like graft member, such as a resorbable material that promotes tissue ingrowth, wherein a sizing pattern is included that comprises linear indicia radiating outward from a stomal aperture. The linear indicia facilitate creation of a resized stomal opening in the graft member sufficiently large to allow passage of the resected bowel portion. A series of cuts made along the indicia create a plurality of flaps about the resized opening that are configured to abut the bowel portion and enhance reinforcement the stomal region after implantation. In one embodiment, the linear indicia comprises a series of weakened (e.g., perforated) lines that facilitate the cutting of the material by a scalpel, scissors, etc.
