Patent ID: 7806870

Claim:
A surgical access device comprising: a) an access port having an elongated body with opposed proximal and distal end portions, the body having a central lumen extending therethrough and having a resilient bulb portion formed between the proximal and distal end portions thereof, wherein the resilient bulb portion is adapted and configured to transition between a first condition in which the bulb portion has a first diameter and a first length and a second condition in which the bulb portion has a second diameter that is less than the first diameter and a second length that is greater than the first length; and b) a telescoping guide tube assembly disposed within the central lumen of the access port body, wherein the guide tube assembly is adapted and configured to transition between a first length corresponding to the first condition of the bulb portion and a second length corresponding to the second condition of the bulb portion, wherein: i) the telescoping guide tube assembly includes proximal and distal tube sections that cooperate together to define a passage within the central lumen of the access port body for an insertion device; ii) each of the proximal and distal tube sections each has a proximal end and a distal end; iii) the proximal ends and distal ends of the proximal and distal tube sections are co-located when the bulb portion is in the first condition; and iv) the proximal end of the distal tube section and the distal end of the proximal tube section are co-located when the bulb portion is in the second condition.
