Elastically deformable surgical access device
First Claim
1. A surgical access device comprising:
- (a) an access port adapted and configured for insertion through an abdominal wall of a patient and to permit insertion and removal of surgical instruments therethrough, the 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 therethrough and having a resilient bulb portion formed between the proximal and distal end portions thereof, at a position on the body permitting engagement of the bulb portion with an interior surface of the abdominal wall, 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;
(b) a tip secured to and extending beyond the distal end portion of the access port, wherein the central lumen extends through the tip; and
(c) an elongated insertion device adapted to extend into the central lumen of the access port body and into the central lumen of the tip, wherein the insertion device is configured to releasably engage the tip so as to facilitate a transition from the first condition of the bulb portion of the access port body to the second condition of the bulb portion of the access port body.

Abstract
A surgical access device is provided having a surgical access port. The surgical access port has an elongated body with opposed proximal and distal end portions, and defines a longitudinal axis. The body has a central lumen extending therethrough and includes a resilient bulb portion formed between the proximal and distal end portions of the body. The resilient bulb portion is adapted and configured to transition, through engagement with an insertion device, 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 and a second length for insertion and removal through a patient'"'"'s abdominal wall, and to be retained in place therethrough. The second diameter is less than the first diameter, and the second length is greater than the first length.

28. A surgical access device comprising:
-
(a) an access port adapted and configured for insertion through an abdominal wall of a patient and to permit insertion and removal of surgical instruments therethrough, the 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 therethrough and having a resilient bulb portion formed between the proximal and distal end portions thereof, at a position on the body permitting engagement of the bulb portion with an interior surface of the abdominal wall, 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; (b) a first engagement means arranged in the distal end portion of the access port body; (c) an elongated guide tube attached to the proximal end portion of the access port body that extends through the proximal portion of the access port body and into the bulb portion, wherein the guide tube and bulb cooperate to define an annular space along a substantial portion of the bulb portion of the access port body when the access port body is in the first condition; and (d) an insertion device adapted and configured to releasably engage the first engagement means so as to facilitate a transition from the first condition of the bulb portion of the access port body to the second condition of the bulb portion of the access port body. - View Dependent Claims (29)

30. A method of forming an access port in a patient, the method comprising the steps of:
-
(a) providing an access port adapted and configured for insertion through an abdominal wall of a patient and to permit insertion and removal of surgical instruments therethrough, the 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 therethrough and having a resilient bulb portion formed between the proximal and distal end portions thereof, at a position on the body permitting engagement of the bulb portion with an interior surface of the abdominal wall, 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 the access port further includes an elongated guide tube attached to the proximal end portion of the access port body that extends through the proximal portion of the access port body and into the bulb portion, wherein the guide tube and bulb portion cooperate to define an annular space along a substantial portion of the bulb portion of the access port body when the access port body is in the first condition; (b) providing an insertion device configured to releasably engage the distal end portion of the access port body; (c) extending the insertion device into the central lumen of the access port body so as to releasably engage the distal end portion of the access port body; (d) elongating the access port with the insertion device to cause the annular space to collapse, the end of the insertion device being engaged with the distal end portion of the access port body; (e) inserting the access port and insertion device through the abdominal wall to a predetermined position, while maintaining the access port in an elongated configuration; and (f) removing the insertion device from the access port, allowing the access port to revert to the first configuration and permitting the annular space to expand, with the bulb portion of the access port engaging an interior surface of the abdominal wall. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
