Patent number: 8597250Abstract: A stability assembly for a trocar cannula includes a conical stability member, a base, and a cannula retention member. The base has a passage defining an inner surface, and a constriction in the passage. The cannula retention member is rotatable within the passage, and advancement of the cannula retention member over the constriction reduces the inner diameter of the passage to restrain a cannula in the passage. Various latch mechanisms including interface surfaces on the base and the cannula retention member can be used in the stability assembly to secure the stability assembly around a cannula. Various conical stability members can be used in the stability assembly.Type: GrantFiled: April 24, 2012Date of Patent: December 3, 2013Assignee: Applied Medical Resources CorporationInventors: David T. Okihisa, Russell E. Ahlberg, Gary M. Johnson, Jeremy J. Albrecht, Michael L. Michaud, Benjamin A. Gianneschi

Patent number: 8287503Abstract: 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.Type: GrantFiled: March 8, 2007Date of Patent: October 16, 2012Assignee: Applied Medical Resources CorporationInventors: Jeremy J. Albrecht, Gigi Au, Eric Nguyen, Donald L Gadberry, John R Brustad, Gary M. Johnson, Charles C. Hart, Michael L Michaud, Matthew M. Becerra, Kennii Pravongviengkham
