摘要： A surgical access device (34) includes a single valve (35) that forms a seal with the body wall (21) and provides an access channel (32) into a body cavity (18). The valve (35) has properties for creating a zero seal in the absence of an instrument, an instrument seal in the presence of instruments, or a hand port to provide access into the cavity (18). The valve can include a gel, preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. A method for making the surgical access device includes the combining of a gelling agent with an oil, preferably by molding. A method for use includes steps for creating an opening with the instrument. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas.

摘要： A surgical device (50) is adapted to facilitate access through an incision (100) in a body wall (18) having an inner surface and an outer surface, and into a body cavity of a patinet. The device includes (55) and second (65) retention members adapted to be disposed in proximity to the outer surface and the inner surface of the body wall, respectively. A membrane (75) extending between the two retention members form a throat (90) which is adapted to extend through the incision (100) and form a first funnel extending from the first retention member (55) into the throat (90), and a second funnel extending from the second retention member (65) into the throat (90). The throat of the membrane has characteristics for forming an instrument seal in the presence of an instrument and a zero seal in the absence of an instrument. The first retention member (55) may include a ring with either a fixed or variable diameter.

摘要： A medical device for viewing inside a body and for retrieving an object from a location within the body, the medical device comprising an endoscope (32) having a tube defining a working channel (36) and a basket (48) engageable with the object. In one embodiment of the invention, the basket (48) does not require a sheath and is disposed through the working channel such that the endoscope operates to contain or activate the sheathless basket. In another embodiment of the invention, a single push wire (66) with a collar (64) at its end is used in place of a sheath to control the opening and closing of the basket. In another embodiment of the invention, a tapered and funnel-shaped sheath (70) surrounding the basket is used to contain or activate the basket. The invention minimizes the basket crossing profile so as to improve fluid flow in the working channel.

摘要： A self-deploying catheter assembly (10) comprises an anchoring device (32) mounted to a tube (14). A distal end (26) of the anchoring device (32) is held in a fixed position by a releasable suture (34) while a proximal end (28) is freely movable between a proximal position and a distal position defined by a stop (23) on the tube (14). During insertion into a body cavity, the anchor (32) automatically maintains a low-profile state with the ends spaced apart. Once fully inserted, the anchor (32) self converts into a high-profile state when the tube (14) is slightly withdrawn, bringing the ends (26, 28) closer together. The suture (34) is disengaged to release the distal end (26) of the anchor (32) in order to facilitate a low-profile state for withdrawal of the assembly (10).

摘要： 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 in compressible 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.-

摘要： A braided stent (10) includes coiled distal and proximal anchors (21), (22) adapted to be disposed in the kidney and bladder, respectively. The stent is threaded onto an elongate member which is advanced distally to position the stent through the ureter. The stent may be releasably coupled to a guidewire (34) and advanced distally by a tubular positioner (30) threaded over the guidewire. Retracting the guidewire into the positioner releases the stent and completes deployment. The stent may include a distal nosepiece (121) which may be inserted through a side port and nto a first lumen tube (123). A road (138) in the first lumen is advanced forward to engage the nose piece and thus move the stent distally. Retraction of the rod disengages the stent and thus completes deployment. A second lumen in the tube receives a guidewire which may be moved independently of the rod and stent.

摘要： Apparatus and methods for endoluminal advancement are described herein. A shape-lockable tissue anchoring assembly generally has an elongate body, a handle assembly, and an anchoring assembly positioned at or proximal to a distal tip of the elongate body. A distal portion of the elongate body may optionally be steerable or curvable. The anchoring assembly may include various expandable (30) or projecting anchoring features to contact and retain tissue relative to the elongate body such that pleated tissue is temporarily immobile relative to the elongate body. This anchoring can be actuated simultaneously with or independently from shape-locking of elongate body. The anchoring assembly can be actuated simultaneously with the shape-locking of the elongate body. Alternatively, the steerable distal portion of the elongate body can be angled against the pleated tissue to retain it while the endoscope is advanced relative to the pleated tissue.

摘要： Flexible shaft systems having interchangeable end effectors are described herein. A shaft with a flexibility sufficient to allow advancement through a lumen of an endoscopic device has an interface at its distal end for engaging a removable end effector tool. The shaft and end effector tool are configured to enable endoluminal deployment through a patient, e.g., through the esophagus and into the stomach. The removable end effector tool may comprise any number of different tools, such as graspers, forceps, scissors, snares, needles, etc., each being interchangeable upon the flexible shaft distal end. Once a procedure is done within the patient, the flexible shaft may be withdrawn and another distal end effector tool may be interchanged. The new end effector tool and flexible shaft can then be reintroduced into the patient.
