Abstract:
1. A surgical device providing sealed access through an incision in a patient, the device comprising: a distal ring insertable through the incision to engage internal body tissue; a tubular diaphragm having a distal end, a proximal end, and an incision engaging portion, the distal end of the tubular diaphragm being coupled to the distal ring, the incision engaging portion configured to engage the incision, and the proximal end of the tubular diaphragm located proximal the distal ring and outside the incision; and an entry seal assembly located proximal the tubular diaphragm, the entry seal assembly configured to maintain a controlled pressurized environment inside the surgical device such that non-adhesive sealing of the surgical device to the patient is provided by engagement of the incision engaging portion of the diaphragm with the incision and engagement of the distal ring to the internal body tissue, said sealing increasing with an increase in pressure within the controlled pressurized environment.
