Abstract: 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.

Abstract: A surgical access device is adapted for performing laparoscopic surgical procedures with multiple instruments passing through the surgical access device and through a single incision in the abdominal wall of a patient with the abdominal cavity pressurized with an insufflation gas. The surgical access device is adapted to provide instrument access to the abdominal cavity for surgical procedures while generally maintaining insufflation pressure in the abdominal cavity. The surgical access device comprises an access pad. The access pad comprises a material formed of a mixture comprising a triblock copolymer, an oil, and a foaming agent. The access pad is adapted to be disposed within an incision within an abdominal wall. The access pad has an external flange and an internal flange integrally formed with the access pad. The external flange is adapted to be disposed external to the abdominal wall in an operative position and the internal flange adapted to be disposed internal to the abdominal wall in the operative position. The access pad is configured to be maintained in the operative position and adapted to form a seal with the abdominal wall. A plurality of openings are formed through the access pad between an external surface and an internal surface of the access pad. The plurality of openings when operatively disposed are in communication with the incision and form working channels between a location external to the abdominal wall and a location internal to the abdominal wall. The access pad is adapted to conform to a surface of an instrument inserted through the working channel. At least a portion of the access pad between the external flange and the internal flange and within the incision between an external surface of the abdominal wall and an internal surface of the abdominal wall is adapted to form an instrument seal with the instrument. Locating the access pad within the incision creates a radially compressive force to provide an axial seal between the access pad and the abdominal wall.

Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring. Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment elements at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force. Rings can also be made inflatable or self-expanding to vary the retraction force. An associated method includes the step of rolling the second ring circumferentially of the third ring to form the circumferential retainer.

Abstract: A percutaneously insertable, needle-sized retractor and system for grasping and retracting tissue in a cavity of a patient. The system comprises a needle-sized trocar sheath having an outside diameter in a range from 10 to 22 gauge, a pointed distal end stylet insertable into the trocar sheath, and a tissue-grasping retractor also insertable through the trocar sheath. The stylet is inserted through the trocar sheath with the pointed distal end extending therefrom. The trocar sheath and stylet are then inserted through a patient's skin and subtending tissue and organs into a desired cavity. When the trocar sheath is inserted, the stylet is removed and the tissue grasping retractor inserted through the sheath and into the cavity. A retaining cap at the proximal end of the sheath fixedly positions the retractor with respect to the trocar sheath while a retention flange positioned around the outside surface of the sheath fixedly positions the sheath with respect to the patient. Thus, the tissue grasping retractor and system grasps and retracts tissue during a minimally invasive procedure with minimal trauma to the patient.

Abstract: A surgical cutting instrument is disclosed for percutaneously debulking tissue through an access sheath commonly used in minimally invasive laparoscopic or endoscopic surgical procedures. The cutting instrument includes a inner rotary member tube having a cutting edge at the distal end thereof for cutting and slicing tissue. The distal end of the cutting member tube extends from the distal end of a stationary sheath which prevents tissue from wrapping around the inner cutting member tube. The inner cutting member tube includes a hollow passageway for suctioning and aspirating tissue and fluid through the tube and into a collection chamber or out through a vacuum or suction line attached thereto. The instrument further includes an outer safety shield having a rounded distal end for preventing the puncture of a surgical tissue bag or from unintentionally cutting tissue by the attending physician. The outer shield has a channel across the distal end through the hollow passageway therein for feeding tissue into the cutting edge and controlling the vacuum applied to the tissue. Vacuum or suction control ports are included at the proximal end of the inner cutting member tube and stationary sheath for also controlling the amount of vacuum or suction applied to the tissue. The surgical cutting instrument includes a control handle for grasping by the physician. A removable collection chamber is connected to a coupler connected to the stationary sheath for collecting tissue therein. The inner cutting member tube extends through the collection chamber to a drive motor or to a remotely positioned rotary drive mechanism. A vacuum line is attached to the collection chamber for drawing tissue and fluid through the inner cutting member tube and into the collection chamber.
