Abstract

The present invention relates to surgical access devices (or surgical access ports) and related methods. More particularly, the present invention relates to such devices that are advantageously adapted for use in single-incision laparoscopic surgical (“SILS”) procedures The present invention also relates to kits and methods involving such surgical access devices.

First claim

The invention claimed is:

1. A kit for performing a laparoscopic surgical procedure through a single incision formed in an abdominal wall of a patient, comprising:
three surgical access ports each including a proximal housing and an elongated body with opposed proximal and distal end portions, the proximal housing of at least one of the three surgical access ports having a tubular insufflation port, the proximal housing of each surgical access port having a pair of diametrically opposed engagement flanges, the body of each surgical access port having a central lumen extending therethrough and having a resilient bulb portion formed between the proximal and distal end portions thereof, wherein the bulb portion is adapted 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, the body of each surgical access port having a telescoping guide tube assembly disposed within the central lumen of the body, wherein the telescoping guide tube assembly is adapted 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, the telescoping guide tube assembly including proximal and distal tube sections that cooperate together to define a passage within the central lumen of the body for an insertion device, wherein each of the proximal and distal tube sections has a proximal end and a distal end, and wherein the proximal and distal ends of the proximal and distal tube sections are co-located when the bulb portion is in the first condition, and 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.

2. A kit as recited in claim 1 , further comprising a packaging enclosure for supporting the three surgical access ports.

3. A kit as recited in claim 1 , further comprising an insertion device having an axial handle assembly including an elongated barrel portion with a pair of diametrically opposed pivoting latching arms at a distal end thereof for releasably engaging the diametrically opposed engagement flanges on the proximal housing of each of the three surgical access ports.

4. A kit as recited in claim 3 , wherein the insertion device further includes an elongated trocar shaft extending from the distal end of the barrel portion and dimensioned to extend through the proximal housing and the body of each of the three access ports, wherein the trocar shaft has a tissue piercing tip at a distal end thereof, and an engagement collar associated with a medial portion thereof for engaging a corresponding engagement collar on a proximal end of the inner tube of the guide tube assembly of each surgical access port.

5. A kit as recited in claim 4 , wherein the proximal housing of each surgical access port has an upper seal member to seal against the trocar shaft of the insertion device when it extends therethrough.

6. A kit as recited in claim 5 , wherein the proximal housing of each surgical access port has a lower seal member adapted to seal the central lumen of the access port in the absence of the trocar shaft of the insertion device.
