    摘要: A self-deploying catheter assembly comprises an anchoring device mounted to a tube. A distal end of the anchoring device is held in a fixed position by a releasable suture while a proximal end is freely movable between a proximal position and a distal position defined by a stop on the tube. During insertion into a body cavity, the anchor automatically maintains a low-profile state with the ends spaced apart. Once fully inserted, the anchor self converts into a high-profile state when the tube is slightly withdrawn, bringing the ends closer together. The suture is disengaged to release the distal end of the anchor in order to facilitate a low-profile state for withdrawal of the assembly.

    摘要: A method for manufacturing a kink-resistant tube having drainage holes is provided. A wire is coated with plastic material and wound around a mandrel forming a plurality of windings. The wound coated wire is heated until the plastic coating material melts and bonds the wire windings to form a wire-reinforced sheath having wire-containing sections and non-wire containing sections. Alternatively, a coated or non-coated wire is wound around a mandrel together with separate polymer filament material and then heated. A filament having an elongated cross-section may be employed with the major axis of the elongated cross-section substantially parallel to the longitudinal axis of the sheath. At least one non-wire containing section is identified by passing light through at least one wall of the wire-reinforced sheath. Image capture and analysis via an optical system and microprocessor automatically identify regions to target a drill for forming holes in the non-wire containing sections.

    摘要: A portable surgical training device is provided. The trainer includes a top cover spaced apart from a base to form a simulated body cavity for locating model organs that are substantially obscured from the field of view of the user. The top cover includes a video display, fixed insertion ports and interchangeable inserts containing simulated tissue layers. The training device has open sides for demonstrating and training lateral surgical techniques including a simulated or live tissue colon attached to a support leg for simulating transanal minimally invasive surgery. A training endoscope with an adjustable focal length for use with the trainer and, in particular, with optical trocars is disclosed. The surgical trainer can be angled and is well suited for training laparoscopic surgery techniques and demonstrating surgical instruments.

    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.
