Elastically deformable surgical access device having telescoping guide tube
First Claim
1. 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.

Abstract
A surgical access device is disclosed that includes an access port having an elongated body with opposed proximal and distal end portions and defining a longitudinal axis, the body having a central lumen extending there through 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 wherein a telescoping guide tube assembly is disposed within the central lumen of the access port body for accommodating an elongated insertion device, 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.

27. A method of performing surgery comprising:
-
a) providing 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 a telescoping guide tube assembly disposed within the central lumen of the access port body, wherein the guide tube assembly includes proximal and distal tube sections that are 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 the proximal and distal tube sections of the guide tube assembly cooperate together to define a passage for a trocar and wherein; i) each of the proximal and distal tube sections each has a proximal end and a distal end; ii) 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 iii) 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; b) inserting a trocar shaft into the central lumen, through the passage defined by the proximal and distal tube sections of the guide tube assembly, to extend the body and transition the bulb portion from the first diameter to the second diameter and to transition the guide tube assembly from the first length to the second length and to cause the proximal end of the distal tube section and the distal end of the proximal tube section to be co-located; and c) inserting the access device through tissue with the bulb portion in the condition of the second diameter and the guide tube assembly in the condition of the second length. - View Dependent Claims (28)
