Abstract: A surgical portal and introducer assembly includes an introducer and a portal member positionable within a longitudinal passageway of the introducer. The portal member is adapted for positioning within a tissue tract and has at least one longitudinal port for passage of a surgical object. The portal member comprises a compressible material and is adapted to transition between a first expanded condition and a second compressed condition. The assembly may include an expandable restraining member that may be disposed within the longitudinal passageway. The restraining member is adapted to expand and compress the portal member to cause the portal member to transition to the compressed condition.

Abstract: A wound closure device for closing a surgical wound is provided. The device includes a flexible base sheet and at least one flexible hemostatic clip for applying pressure to a patient's tissue. The flexible base sheet includes at least a first end and a second end, as well as an aperture extending through the base sheet longitudinally from proximate to the first end toward the second end. The aperture has a first and a second longitudinally extending edge. The clip has a first end, a second end, a top, a bottom, and at least a first and a second clamping member. Each clamping member has a distal edge. The clip is attachable to the base sheet.

Abstract: The present disclosure relates to devices for introducing a port within a body cavity. The system includes a compressible port that collapses radially for positioning into an introducer that is inserted into an incision. Methods for using the devices are also described.

Abstract: A method for cooling of a brain with localized hypothermia allowing for maintenance of the core body temperature is achieved by positioning a cooling catheter within a ventricular cavity of the brain. The cooling catheter includes an inlet channel and an outlet channel providing for a closed flow of a cooling fluid into and out of the cooling catheter. A sack is formed at a distal end of the cooling catheter. The sack is in fluid communication with distal ends of the inlet channel and the outlet channel such that the sack is continually flushed with the cooling fluid as the cooling fluid flows into and out of the cooling catheter. The sack, when filled, takes the shape and size of the ventricular cavity filling the ventricular cavity in which it is positioned. The method further includes cooling the cooling catheter and the ventricular cavity through the closed flow of the cooling fluid through the cooling catheter.

Abstract: A surgical portal and introducer assembly includes an introducer dimensioned for at least partial positioning within a tissue tract, and having a longitudinal introducer channel extending therethrough and a portal positionable within the longitudinal channel of the introducer. The introducer defines leading and trailing ends, and further has a frangible segment adapted to separate to expose the introducer channel. The portal has at least one longitudinal port for passage of a surgical object. The portal comprises a compressible material and is adapted to transition from a first expanded condition to a second compressed condition upon advancement through the longitudinal channel of the introducer to facilitate passage through the introducer whereby, upon separating of the frangible segment, the portal is released from the longitudinal channel to transition toward the first expanded condition to be generally secured within the tissue tract.

Abstract: A method for determining the depth, direction, and/or angle of an instrument inserted into a cavity in which a user compares the light output of a light source assembly at a distal end of the instrument with known light outputs for that light source assembly. The instrument may include a plurality of light source assemblies having light outputs of different colors and intensities. The instrument may be an introducer that enables a port, e.g., a foam port, to be accurately positioned within an incision.

Abstract: A surgical portal and introducer assembly includes an introducer defining a longitudinal axis and having a longitudinal passageway and a portal member positionable within the longitudinal passageway of the introducer. The portal member is adapted for positioning within a tissue tract and has at least one longitudinal port for passage of a surgical object. The portal member comprises a compressible material and is adapted to transition between a first expanded condition to facilitate securing of the portal member 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 member within the tissue tract. The assembly may include an expandable restraining member at least partially disposed within the longitudinal passageway of introducer.

Abstract: Tissue management methods can include inserting a clamping device into a vessel and clamping a vessel wall via the clamping device. Tissue can be dilated about the clamping device and an anastomotic device provided to the vessel.
