Patent number: 9265899Abstract: Systems, devices, and methods permit insufflation of a body cavity prior to the insertion of a cannula into the body cavity. Some embodiments of an access system comprise an obturator, a trocar, and a fluid flow channel. The access system has a closed configuration, in which a distal end of the access system is fluidly isolated from the fluid flow channel, and an open configuration, in which the distal end of the access system is fluidly connected to the fluid flow channel, thereby permitting fluid flow, for example, an insufflation gas into a body cavity.Type: GrantFiled: January 26, 2009Date of Patent: February 23, 2016Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 9259238Abstract: 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: January 26, 2015Date of Patent: February 16, 2016Assignee: Applied Medical Resources CorporationInventors: Jeremy J.
