The at least one cable member has a first cable end connected to a first radial section of the seal member and a second cable end connected to a second radial section of the seal member displaced from the first radial section. The first and second cable ends are adapted to be laterally displaced relative to the longitudinal axis during offset lateral movement of the surgical object, to thereby cause corresponding lateral displacement of the inner seal portions of the seal member whereby the inner seal portions maintain the substantial fluid tight sealing relation with the surgical object. | 10-15-2009 |
| 20100048994 | VISUALIZED ENTRY TROCAR WITH MOVING BLADE - An obturator for penetrating tissue includes an outer member defining a longitudinal axis, and having proximal and distal ends, a leading member disposed adjacent the distal end of the outer member and having a tissue contacting outer surface, and a blade mounted adjacent to the leading member. The blade is adapted for at least traversing movement relative to the longitudinal axis to thereby traverse the outer surface of the leading member to facilitate penetrating of tissue during advancement of the leading member within the tissue. The leading member may include an optical window adapted to permit passage of light therethrough for detection by a clinician. | 02-25-2010 |
| 20100063359 | ENDOSCOPIC/LAPAROSCOPIC INTRODUCER SLEEVE - A protective sleeve apparatus for protecting an endoscopic or laparoscopic instrument includes an elongated tubular member having an open proximal end and an open distal end. The elongated tubular member is sized and configured to receive a laparoscopic or endoscopic instrument therethrough. The tubular member has a folded section adjacent the distal end in releasable engagement with an intermediate section of the tubular member to define a substantially enclosed sleeve to receive the instrument and substantially prevent entry of contaminants within an interior of the tubular member. The folded section is releasable from the intermediate section upon exertion of a proximal force to the tubular member to facilitate removal of the tubular member along the instrument. | 03-11-2010 |
| 20100152664 | TROCAR ENTRY INCORPORATING AN AIRBAG - A safety trocar assembly incorporating an airbag is provided to prevent overpenetration of the safety trocar assembly through an abdominal wall and into a body cavity. The safety trocar assembly includes an airbag cannula having an expandable airbag proximal of the distal end of the cannula. A sensing device is located at a distal end of the cannula for detecting changes in conditions at the distal end of the cannula. A trigger mechanism is provided on the cannula and operates to inflate the airbag in response to a change in condition detected by the sensing device. | 06-17-2010 |
| 20100249523 | SURGICAL ACCESS PORT AND ASSOCIATED INTRODUCER MECHANISM - A surgical portal assembly includes a portal member adapted for positioning within a tissue tract and defining a longitudinal axis with leading and trailing ends. The portal member includes at least one longitudinal port for passage of an object. The portal member comprises a compressible material adapted to transition between a first expanded condition to facilitate securing of the portal within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate at least partial insertion of the portal within the tissue tract. The portal assembly also includes an elongated member extending through the at least one longitudinal port and mechanically couplable to the portal member adjacent the leading end thereof. The elongated member is adapted to move through the at least one longitudinal port in a trailing direction to exert a compressive force at least adjacent the leading end to cause the portal member to transition toward the compressed condition. | 09-30-2010 |
| 20100274081 | VISUAL VERESS NEEDLE ASSEMBLY - A visual veress needle assembly is provided including an optically conductive veress needle for puncturing tissue and having a hollow interior and an optical stylet insertable through the hollow interior of the veress needle. The veress needle is constructed of translucent material enabling light to pass through from a proximal end to a distal end to illuminate the area of the incision and the operative site. The optical stylet includes a lens at a distal end for obtaining an image of the operative site and a connector at the proximal end for transmitting optical data to auxiliary viewing devices. The distal end of the stylet is flexible and incorporates structure to orient the lens relative to the hollow veress needle. | 10-28-2010 |

The balloon dissector includes a tubular member having a bore, an inflatable dissection balloon secured to a distal end of the tubular member, and an obturator slidably mounted in the bore of tubular member. The elongate collar includes a body portion which has a polyhedron prism shape and a tip portion. The body portion may extend from a surgical site inside the patient's body to the outside the patient's body. The elongate collar is made from a suitable foam or gel material having sufficient compliance to form a seal with the surgical objects and sufficiently compliant to accommodate off-axis motion of cannula during a surgical procedure. | 04-07-2011 |
| 20110082341 | UNIVERSAL HEIGHT FOAM PORT - A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus is configured to have different lengths. In one embodiment, the surgical includes a seal anchor member having two ends, and one of which is adapted to fold resulting in a plurality of folded states. Each folded state corresponds to a different length of the seal anchor member. The seal anchor member includes a slot to facilitate transition within the plurality of folded states.
