摘要： Devices and methods for laparoscopically repairing a hernia are described. In some embodiments, a laparoscopic instrument is used to deploy one or more tissue anchor assemblies into the edges of the fascia tissue surrounding or adjacent to the hernia defect. The tissue anchor assemblies are used to cause the fascia tissue to be approximated to facilitate the repair procedure, to improve healing, and to reduce the incidence of recurrence.

摘要： Apparatus and methods optimize anchoring force in securing tissue folds. Over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable designs configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue.

摘要： An endoluminal surgical instrument has first and second steering controls on a handle. A flexible shaft attached to the handle has a distal steerable end including a first link and a second link separated by a plurality of intermediate links. First and second steering elements, such as pairs of steering wires, are linked to first and second steering controls and to the first and second links. One or more of the links is pivotable through an angle of at least 30 degrees relative to an adjoining link. The set back position of the second steering elements from the first steering elements, and the pivoting capability of the links allows the steerable end to be steered into a small bend radius. This makes the instrument highly maneuverable for use in endoluminal surgery, such as incision-less surgery of the stomach.

摘要： Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably dispose through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

摘要： Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism, either within the anchor itself or positioned proximally of the anchor, may allow for the uni-directional translation of the anchor while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates cinching of the tissue plication between the anchors, and it may be utilized in one or several anchors in cinching a tissue fold.

摘要： Tissue manipulation and securement systems are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is also pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration for receiving tissue. The tissue manipulation assembly may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly.

摘要： A method of reducing the cross-sectional area of a gastrointestinal lumen is provided wherein a delivery catheter having a needle, one or more anchors disposed within the needle and a suture coupled to each anchor is advanced into the gastrointestinal lumen, the needle extended through the tissue wall, and an anchor ejected from a distal tip of the needle through the tissue wall. The needle is then repositioned against an opposing tissue wall, another anchor deployed from the needle through the opposing tissue wall, and the tissue walls approximated by applying tension to the sutures.
