摘要： The invention is directed to a device and method for securing a passed surgical suture in a manner similar to a tied knot. The suture securing device comprises a male piece having a top portion, a center shaft having one end connected to the top portion, and an end member having a capturing feature connected to another end of the center shaft; and a female piece having a top end and a bottom end comprising a column being generally cylindrical in shape and forming a hollow opening along its length, wherein the opening slidingly receives the center shaft and a suture to be captured and held by the capturing feature, the suture being secured in place between the column and the center shaft. The assembled male and female pieces are irreversibly interlocked and form a lightly compressed, convoluted or tortuous pathway. The capturing feature is formed to engage and obliquely capture the suture from different angles. The radii of the male and female pieces are preferably greater than the radius of the suture. The securing device may further comprise a link formed between the male and female pieces. The link may be a tether formed when the male and female pieces are formed. The link may be severed and removed after placement and assembling of the male and female pieces. In another aspect of the invention, a method for applying a suture securing device is disclosed comprising the steps of: (1) providing the suture securing device of the invention; (2) aligning the male piece and the female piece at a desired location for applying the suture securing device; and (3) pressing the center shaft of the male piece into the opening of the female piece. The method may further comprise the step of applying a compressive load on the male piece to dislodge an enlargement from an undercut of the female piece and to place the male piece and the female piece in a condition where they may be advanced to a desired position along the suture.

摘要： A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed. In another aspect of the invention, a mandrel is used as part of an extrusion process. In another aspect of the invention, another coating or outside layer could be formed over the spring reinforcement by dipping in a solvent based solution. In yet another embodiment of the invention, a braid such as a polyester braid may be used instead of or in addition to the coil spring to form a kink-resistant sheath.
