US Classification:

60416404, 60416501, 60416701, 604 9601

Abstract:

A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.

International Classification:

A61M 5/178

US Classification:

60416706, 60416701, 60416401

Abstract:

A surgical access port comprises a valve or instrument seal that separates the instrument contact function from the instrument conforming function. Embodiments of the instrument seal comprise in instrument contact element that extends through an opening in a compression element, thereby defining an instrument orifice that seals with an instrument extending therethrough. Embodiments of the instrument contact element comprise a non-distensible membrane or film, for example, as a tube or cylinder. Some embodiments of the instrument contact element have an hourglass configuration with a first end proximal of the opening of the compression element and a second end distal of the opening of the compression element. Other embodiments of the instrument contact element “wrap around” the opening in the compression element, with the first end and the second end secured to the same side of the opening, for example, proximal of the opening. Embodiments of the compression element comprise an elastomeric seal, for example, a septum seal and/or a gel seal.

International Classification:

A61B 1/32

US Classification:

600208

Abstract:

A surgical access system comprises a wound retractor comprising an outer anchor, an inner anchor, and a flexible, tubular sheath extending therebetween. Embodiments of the outer anchor comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. The sheath comprises a plurality of fibers or strands that improve the abrasion and puncture resistance thereof. Consequently, the surgical access system is useful in procedures in which damage to the sheath is likely, for example, orthopedic hip replacement, and spinal procedures. In some embodiments, the sheath tapers from the outer ring to the inner ring.

Abstract:

An incrementally adjustable wound retractor (), having a first ring () with a diameter greater than the desired diameter of the wound incision, a flexible second ring (), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (), disposed in a generally cylindrical form between the first and second rings (), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.
