An instrument access device (500) comprises a distal O-ring (11) for insertion into a wound interior, a proximal member for location externally of a wound opening and a sleeve (12) extending in two layers between the distal O-ring (11) and the proximal member. The proximal member comprises an inner proximal ring member (25) and an outer proximal ring member (24) between which the sleeve (12) is led. A seal housing (300) is mounted to the inner proximal ring member (25). A gelatinous elastomeric seal (302) with a pinhole opening (303) therethrough is received in the housing (300). An instrument may be extended through the seal (302) to access the wound interior through the retracted wound opening in a sealed manner.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

A laparoscopic surgery support system can include a plurality of ports configured to receive a trocar therethrough and a plurality of arms connecting the plurality of ports together and configured to allow fixation of a relative position of the plurality of ports. For example, the plurality of ports can include three or more ports.

A surgical access attachment for use with a surgical access device is disclosed. The surgical access attachment includes a ring and an access portion assembly. The ring is configured to engage a proximal portion of a surgical access device. The access portion assembly includes at least one flexible tab having an engagement structure. The engagement structure is configured to selectively engage the ring. The access portion assembly is configured to retain a seal. The access portion assembly is configured to disengage from the ring in response to a predetermined amount of force exerted on one flexible tab of the at least one flexible tab.

Embodiments of a surgical access port system that comprises a retractor that is adapted for being coupled to a cap and that is particularly useful in natural orifice surgery are described. The retractor comprises an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice; a tubular body; a funnel segment extending between and coupling the outer ring and the tubular body, wherein the funnel segment provides a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body, which is sized to fit within a natural orifice with minimal distention of the orifice; and an inflatable member disposed around the distal end of the tubular body, the inflatable member sized and configured to fit snugly around the tubular body in the deflated condition and to expand against the wall of the natural orifice in the inflated state to thereby stabilize and retain the retractor within the orifice.

A portal saver assembly with a dermal fixation device that is removably attached to a length-adjustable portal saver. The portal saver assembly includes a tubular body having a rigid proximal end with threads and a proximal adjustment body having an outer ridge and an inner bore with threads. The threads on the rigid proximal end of the tubular body are configured to mate with the threads on the inner bore of the proximal adjustment body. The portal saver assembly also includes a dermal fixation device with a central bore and a locking mechanism around the central bore. The outer ridge of the proximal adjustment body is removably attached to within the central bore by the locking mechanism.

An endoluminal punch system including a sheath and dilator. The endoluminal punch may include energy delivery system capable of being transmitted from the proximal end to the distal end of the endoluminal punch to assist with tissue crossing and incisions. The dilator may include selectively deployable cutting mechanism to create incisions in tissue that are larger than their basic external diameter. The system may also be configured to reduce the risk of generating plastic emboli during insertion of the endoluminal punch.

A surgical access device includes an instrument valve housing including a cannula extending distally from the instrument valve housing. The cannula defines a longitudinal axis. An anchor is supported at a distal end portion of the cannula. A retainer is configured to be removably engaged with cannula. The retainer includes a first member defining a semi-circular shape. The first member defines a first arm having a first lateral surface, and a second arm having a second lateral surface. A first magnet is positioned in the first arm and a second magnet is positioned in the second arm. A second member defines a semi-circular shape. The second member defines a third arm having a third lateral surface, and a fourth arm having a fourth lateral surface. A third magnet is positioned in the third arm and a fourth magnet is positioned in the fourth arm.

A device that holds a radial sheath, catheter or similar structure in place during surgical procedures. The device has a strap configured to fit around a patient's wrist and a two-part section that includes a sheath holder or clamp. The clamp is configured to accept a free end of the sheath or other device and to allow the physician access to the open end of that sheath so that they can insert instruments through it. The second section contains a compression device that, when positioned over the puncture site, can be expanded such that it provides pressure and patent hemostasis to the site to stop bleeding. Adhesive surfaces with peel away releasable liners on one or more surfaces of the device allow the flap featuring the compression balloon to be folded over onto the flap containing the sheath clamp and hold it in place.

A port fixation device is disclosed and includes a body portion and a plug. The body portion includes a circular portion, a first tab, and a second tab. The circular portion defines an aperture which is configured to allow a surgical access port to extend therethrough. The first tab and the second tab are disposed in mechanical cooperation with the circular portion. Movement of the first tab with respect to the second tab from a first position to a second position causes a diameter of the aperture to change from a first size to a second size. The first size is smaller than the second size, and the first position of the first tab is its rest position. The plug is disposed in mechanical engagement with the body portion, and has sufficient elasticity to remain engaged with the body portion when the first tab is in the first position and in the second position.
