Abstract:
Disclosed is an infinitely adjustable depth stop for a laparascopic instrument having a shaft, the depth stop including a first component having a first annular space adapted to allow the shaft to be fitted therethrough. The first annular space has a reducible diameter and an interference surface against which the shaft may be fitted. Upon reduction of the reducible diameter, the interference surface frictionally engages the shaft to arrest relative movement of the depth stop along the shaft. The frictional engagement may be along a curve, a spiral curve, or an area. Means are also provided to reopen the reducible diameter to release the depth stop.
Abstract:
A wound closure assembly and method for its use. The wound closure assembly includes a curved inserter having a distal end and a proximal end, a filamentary element extending between a proximal end and a distal end, wherein the proximal end is coupled to the proximal end of the curved inserter, a first anchor coupled to the filamentary element between its first and second ends, and a second anchor positioned at the distal end of the filamentary element. The filamentary element is configured to form a slip knot between the first and second anchors so as to enable the distance between the first and second anchors to be decreased by pulling on the proximal end of the filamentary element. The distal end of the curved inserter is received within a channel in the first anchor that extends along its longitudinal length.
Abstract:
A deployment device for anchoring a suture to a suture anchoring device, which is made from a helically coiled member, includes a winding tube for winding a suture around the coiled member in a helical path such that the suture is attached to at least one turn of the coiled member. A support mechanism is also provided for supporting the suture anchoring device during the winding of the suture around the coiled member. The deployment device can be used for anchoring a string and the like to any helically coiled member.
Abstract:
A surgical device for severing tissue, the surgical device comprising; a first shaft having a first internal lumen and a first slot disposed at a distal end; a clamp slidingly disposed in the first slot between open and closed positions to capture tissue in the first slot, the clamp having a clamping surface disposed at a distal end; at least one electrode for applying RF energy to the tissue captured in the first slot; a cutting blade slidingly disposed in the first slot between open and closed positions, the cutting blade having a cutting edge to sever the tissue; first actuation means for actuating the clamp between the open and closed positions; and second actuation means for actuating the cutting blade between the open and closed positions.
Abstract:
A needle for endoscopic surgery is curved into an arc of more than 180.degree. and twisted, so that it forms a part of a spiral, with a lateral offset between the needle point and barrel. The needle is sized to fit through a 10 mm trocar and is also blackened, to improve its visibility in a bloody field. The needle curvature is preferably not constant over its entire length, so that different sections have different radii of curvature. The needle is particularly well adapted for performing laporascopically a procedure (Burch Colposuspension) that is used to treat female stress incontinence.

Abstract:
An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft extending from the housing, the elongated shaft having a proximal end coupled with the housing and a distal end remote therefrom, and a firing system for dispensing surgical fasteners from the distal end of the elongated shaft. The firing system includes a firing rod disposed in the elongated shaft, the firing system having a firing cycle with a first stage for advancing the firing rod toward the distal end of the elongated shaft at a first rate of speed and a second stage for advancing the firing rod toward the distal end of the elongated shaft at a second rate of speed that is greater than the first rate of speed.
Abstract:
An implant insertion system includes an implant, such as a surgical mesh, having at least one insertion tip secured to the implant. Each insertion tip has a tapered distal end, a proximal end, a base extending proximally from the tapered distal end, and a central lumen formed in the base having an opening facing the proximal end of the insertion tip. The system includes an insertion device having an outer shaft and a latching assembly provided at a distal end of the outer shaft that is insertable into the opening of the central lumen for selectively locking the insertion tip to the latching assembly. The latching assembly has an outer dimension that is changeable from expanded state for locking the insertion tip to the latching assembly to a non-expanded state for unlocking the insertion tip from the latching assembly.

Abstract:
A tissue anchor comprising a body having a longitudinal axis, a proximal end with one set of dimensions and a projected surface area, a distal end with a second set of dimensions and a projected surface area where the respective dimensions of the first and second ends are not identical and the projected areas are substantially the same. The tissue anchor may further have a fixing member to attach the anchor and one or more tissues together or to attach the other structures to tissue.
