Abstract: An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending 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 is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and 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.

Abstract: A medical tubing being flexible and kink-free as gas insufflation tubing and non-collapsible as suction/irrigation tubing is provided. The tubing is lightweight and thin-walled. The tubing has a generally rigid but thin walled with a structural shape or is generally soft and thin-walled tubing with a hard re-enforcement.

Abstract: 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.

Abstract: The application 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.

Abstract: A retraction device that optionally includes a sheath that traverses from outside the body to a body cavity inside the body. The retraction device may include an outer retention ring and a plurality of shapeable extending elements coupled to the retention ring and extending distally therefrom, the extending elements being configured to transition from a first, low-profile, insertion condition to a second, expanded, high-profile retention condition in which distal ends of the extending elements extend radially outwardly. Alternatively, the retraction device may include an outer ring having a substantially annular shape with an adjustable circumference, the outer ring being divided into a plurality of curved ring segments, with a substantially tubular structure extending distally from the outer ring, wherein the diameter of the outer ring is increased by moving the curved ring segments further apart and the diameter is decreased by moving the curved ring segments closer together.

Abstract: A retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a deployable, adjustable frame that supports the sheath and that, together with the sheath, retracts the incision. The retraction device may include an outer ring and an inner ring coupled to opposing ends of the sheath and further include means to place the sheath in tension between the inner and outer rings, thereby retracting the incision.

Abstract: A retraction device for retracting an incision in a body wall includes a sheath that traverses through the incision from outside the body to a body cavity inside the body. The retraction device may include a first, distal retention ring, a second, proximal retention ring, a circumferential, tubular sheath that is coupled to the first and second retention rings, a plurality of tensioning straps, and a proximal lock ring, wherein each of the plurality of straps is coupled to the distal retention ring and extends proximally through the lumen of the sheath and the proximal retention ring. The lock ring is sized and configured to capture the straps between an inner surface of the proximal retention ring and an outer surface of the lock ring. The lock ring is adapted to be positioned within a lumen of the proximal retention ring with the straps exiting between the proximal retention ring and the lock ring.
