Abstract: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube disposed within a hydrophilic sheath, and a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The sheath may be disposable to permit reuse of the overtube. Fail-safe tensioning mechanisms may be provided to selectively stiffen the overtube to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The fail-safe tensioning mechanisms reduce the risk of reconfiguration of the overtube in the event that the tension system fails, and, in one embodiment, rigidizes the overtube without substantial proximal movement of the distal region. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument, while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

Abstract: An access device particularly adapted for use in laparoscopic surgery facilitates access with instruments, such as the hand of the surgeon, across a body wall and into a body cavity. The device can be formed of a gel material having properties for forming a zero seal, or an instrument seal with a wide range of instrument diameters. The gel material can be translucent facilitating illumination and visualization of the surgical site through the access device.

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: 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.

Abstract: 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.

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.
