Abstract: 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.

Abstract: A surgical valve includes a housing with a proximal housing portion and a distal housing portion cooperating to define a gel cavity. A seal material is disposed in the gel cavity and includes a gel having flow characteristics and incompressible characteristics. A distal guide tube is provided to facilitate retrograde insertion of a surgical instrument into the seal material. During assembly, pressure is applied by the housing portions to the seal material in order to form a circumferential seal and to close an instrument channel. Manufacture can be facilitated by use of a mandrel for maintaining the structural elements in axial alignment. Complimentary screw threads disposed between the first and second housing portions can be used to pressurize the gel and thereby create a locking force on an inserted instrument. Detented tabs can be provided to facilitate control of this locking force.

Abstract: A surgical access device is adapted for performing laparoscopic surgical procedures with at least one instrument passing through the surgical access device and through an incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device comprises an access seal. The material of the access seal is adapted to form a seal to generally maintain insufflation pressure within the abdominal cavity. At least one opening is formed through the material of the access seal between a proximal portion and a distal portion of the access seal. The at least one opening when operatively disposed is in communication with the incision and forms a working channel between a location external to the abdominal wall and a location internal to the abdominal wall. The material of the access seal conforms to a surface of an instrument inserted through the working channel.

Abstract: 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.

Abstract: 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.

Abstract: 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 of positioned proximally of the anchor may allow for the uni-directional translation 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 the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.

Abstract: Systems for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms 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. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

Abstract: Interlocking tissue anchor apparatus and methods 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 disposed 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. Anchor assemblies can be delivered via the tissue manipulation assembly into or through the tissue. The anchors can incorporate various temporary interlocking features or spacing elements between one another to ensure that an anchor is not prematurely ejected from the needle assembly. This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.
