Access port device for use in surgery
First Claim
1. An access port for use in surgery comprising:
- an elongate sleeve of flexible material having an entry opening located at a proximal end of the sleeve and an exit opening located at a distal end of said sleeve,an inflatable chamber surrounding said sleeve and extending substantially coaxially therewith from the proximal end of the sleeve for a distance along the length of said sleeve, said inflatable chamber when inflated operating to collapse said sleeve to close said entry opening, said sleeve being attached to and surrounded by said inflatable chamber with said sleeve extending through said inflatable chamber and outwardly therefrom to provide a projecting flexible sleeve portion extending outwardly from the inflatable chamber to the exit opening at the distal end of said sleeve whereby said projecting sleeve portion can be inserted through an incision and into a patient'"'"'s body cavity to provide a flexible sleeve portion adjacent to said exit opening within said body cavity free of a surrounding inflatable chamber.

Abstract
An access port device (40) for use in surgery is provided which comprises a sleeve (41,42) having an exit opening located at a distal end thereof for insertion into an incision made in a patient'"'"'s body, the exit opening allowing access to the patient'"'"'s body cavity. The device (40) also includes exit opening sealing means for insertion into the incision. There is an entry opening located at a proximal end of the sleeve (41,42) and entry sealing means for sealing the device in the region of the entry opening, so that when the patient'"'"'s body cavity is inflated by gas, the exit sealing means and the entry sealing means prevent substantial leakage of gas from the patient'"'"'s body cavity while the entry sealing means also provides access for a surgeon'"'"'s hand or surgical instrument and sealing about the arm remaining outside the access port device. The invention also relates to surgical instruments for use with such an access port and to a surgical drape for use in surgery using the access port and instruments of the invention.

35. An access port for use in surgery comprising:
-
an inflatable chamber having two, flexible, opposed substantially flat chamber inner sidewalls which collapse together into contact in response to pressure in said inflatable chamber, said inner chamber sidewalls defining a passage through said inflatable chamber between a chamber entry opening and a chamber exit opening at a chamber exit end; and a flexible non-inflatable extension section secured to the chamber exit end of said inflatable chamber in communication with the passage therethrough, said extension section being adapted to be inserted through an incision into a patient'"'"'s body cavity to provide a flexible sleeve portion extending outwardly from the inflatable chamber, said extension section having a sleeve entry opening and a sleeve exit opening and two substantially flat, flexible sidewalls which form a flap valve at said sleeve exit opening. - View Dependent Claims (36, 37)

- 38. An access port device for use in surgery comprising a sleeve having an entry opening located at a proximal end of the sleeve and having an exit opening located at a distal end thereof for insertion into an incision made in a patient'"'"'s body, the exit opening allowing access to the patient'"'"'s body cavity, characterized in that the device includes exit opening sealing means provided by the sleeve being collapsible on itself by gas pressure within the abdominal cavity of the patient at or adjacent the distal edges of the sleeve, the sleeve being formed by sheets of flexible, gas impermeable, sterilisable, biocompatible material having joined side edges which are collapsible together by gas pressure within the abdominal cavity of the patient at or adjacent, the distal end of the sleeve so as to provide a seal, whereby when the patient'"'"'s body cavity is inflated by gas, the exit sealing means prevents substantial leakage of gas from the patient'"'"'s body cavity through the sleeve while providing access for a surgeon'"'"'s hand or surgical instrument.
