摘要： A surgical access device includes a single valve that forms a seal with the body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon, thereby providing hand access into the cavity.

摘要： 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.

摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.

摘要： The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient's abdomen is reduced.

摘要： An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed comprising a shaft having an insufflation channel extending along an axis between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end, a tip at the distal end of the shaft, and at least one vent hole formed at the tip or the shaft being in connection with the insufflation channel and being adapted to expel the fluid under pressure to insufflate the abdominal region. At least one of the tip and the shaft is formed of a translucent or transparent material such as polycarbonate to facilitate visualization of the abdominal wall and the abdominal region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel. The tip may be blunt, the shaft and the tip may be integrally formed, and the vent hole may be of any geometric shape including round, oval, square and rectangular. The blunt tip may further comprise a marker to indicate penetration of the abdominal wall. In another aspect, the tip may be sharp, pointed or bladed to facilitate penetration of body tissue.

摘要： 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.

摘要： A trocar having a cannula and a valve housing with a polygonal configuration, provides for a floating septum where the float is encouraged in a first direction and restricted in a second direction. The septum includes multiple septum valves which may function with a comnron zero-closure valve, or individually in a valve assembly with an associated zero-closure valve. Various seals can be configured to prevent blow-back. Cup valves, check valves, and reciprocating valves are contemplated, along with various skirt configurations for maintaining pressurized air within the trocar.

摘要： A suturing apparatus is adapted for joining two objects which define a near side and a far side. The apparatus includes an elongate support structure having a working channel and an axis extending between a proximal end and a distal end. The structural support is adapted to be positioned over a guidewire extending between the two objects, in an operative position wherein the proximal end is disposed on the near side and the distal end as disposed on the far side. Removal of the guidewire permits use of a stylet for positioning a suture to extend within the working channel from the proximal end to the distal end. A pair of hooks are movable from a proximal position at the proximal end of the support structure through the objects and a pair of slots in the support structure, to a distal position wherein the hooks engage the suture within the working channel at the distal end of the support structure. The actuator is then operable to move the hooks and the engaged suture from the distal position to the proximal position in order to facilitate tying of the suture and joining of the two objects. Alternatively, suture loops can be carried through the objects by unidirectional hooks and into the working channel. The hooks can then be withdrawn leaving the suture loops in the working channel where they can be engaged by a snare and withdrawn proximally between the two objects. Suturing pledgets can be added to the suturing apparatus prior to operative disposition, and a backing member can be provided to support at least the pledgets when the hook passes through the object.
