Abstract
Abstract A multiple surgical cuff for introduction into a body passage such as a trachea, bladder and urethra opening or artery comprising a tubular base member encircled by proximal, distal and middle double cuff members. The middle double cuff member comprises an inflatable tubular inner cuff member encircled by a distensible tubular outer cuff member, whose wall is multiperforated at spaced points. Separate passage means communicate with each cuff member so that each can be inflated to press against the adjacent portion of the body passage wall. Another passage communicates with the space between the inner and outer cuff members of the middle double cuff member to permit the introduction of a surgical fluid such as an anesthetic in that space, so that expansion of the inner cuff member forces the fluid onto the adjacent portion of the wall of the body passage. Still another passage communicates with the space along the tubular base member between the middle and proximal cuff members and permits the introduction of a surgical fluid, such as a cleansing saline solution, or to suck out loose thicker material from there and also enables continuous cooling and washing by an inflow and separate outflow. A plurality of side window openings in the tubular base member on the near side of the proximal cuff member permits the continued flow of blood when the body passage is an artery and continued flow is indicated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
397 words
A multiple surgical cuff for introduction into an integral body passage comprising: (A) A tubular base member having an unblockable lumen; (B) A middle cuff member comprising (1) an imperforate inflatable tubular inner cuff member encircling said tubular base member, (2) a distensible tubular outer cuff member encircling said inner cuff member, the wall of said outer cuff member being multiperforated at spaced points; (C) First passage means for communicating with the space between said inner cuff member and said outer cuff member for introducing a fluid into said space; (D) Second passage means communicating with the space between said inner cuff member and said tubular base member for inflating said inner cuff member to displace wall portions thereof toward the wall of said outer cuff member, whereby the spacing between the opposed walls of said inner and outer cuff members is reduced to transmit fluid outwardly through the perforations of the wall of said outer cuff member or to close said integral body passage; (E) A proximal cuff member comprising a first inflatable tubular cuff member encircling said tubular base member on the near side of said middle cuff member; (F) Third passage means communicating with the space between said first inflatable tubular cuff member and said tubular base member for inflating said first inflatable tubular cuff member, whereby said proximal cuff member can press against an adjacent body passage portion of said integral body passage; (G) A distal cuff member comprising a second inflatable tubular cuff member encircling said tubular base member on the far side of said middle cuff member; p1 (H) Fourth passage means communicating with the space between said second inflatable tubular cuff member and said tubular base member for inflating said second inflatable tubular cuff member, whereby said distal cuff member can press against an adjacent body passage portion of said integral body passage; and (I) Fifth passage means communicating with the space along said tubular base member between said proximal and middle cuff members; (J) Wherein said middle cuff member, said proximal cuff member and said distal cuff member are permenantly located substantially adjacent to each other with respect to said tubular base member; (K) Whereby, with deflation of said middle cuff member, a continuous flow of fluid may be fed past a body passage portion between said proximal and distal cuff members via said first and fifth passage means.
Claim 2
Dependent Claim

A multiple surgical cuff for introduction into an integral body passage comprising: (A) A tubular base member having an unblockable lumen; (B) A middle cuff member comprising (1) an imperforate inflatable tubular inner cuff member encircling said tubular base member, (2) a distensible tubular outer cuff member encircling said inner cuff member, the wall of said outer cuff member being multiperforated at spaced points; (C) First passage means for communicating with the space between said inner cuff member and said outer cuff member for introducing a fluid into said space; (D) Second passage means communicating with the space between said inner cuff member and said tubular base member for inflating said inner cuff member to displace wall portions thereof toward the wall of said outer cuff member, whereby the spacing between the opposed walls of said inner and outer cuff members is reduced to transmit fluid outwardly through the perforations of the wall of said outer cuff member or to close said integral body passage; (E) A proximal cuff member comprising a first inflatable tubular cuff member encircling said tubular base member on the near side of said middle cuff member; (F) Third passage means communicating with the space between said first inflatable tubular cuff member and said tubular base member for inflating said first inflatable tubular cuff member, whereby said proximal cuff member can press against an adjacent body passage portion of said integral body passage; (G) A distal cuff member comprising a second inflatable tubular cuff member encircling said tubular base member on the far side of said middle cuff member; p1 (H) Fourth passage means communicating with the space between said second inflatable tubular cuff member and said tubular base member for inflating said second inflatable tubular cuff member, whereby said distal cuff member can press against an adjacent body passage portion of said integral body passage; and (I) Fifth passage means communicating with the space along said tubular base member between said proximal and middle cuff members; (J) Wherein said middle cuff member, said proximal cuff member and said distal cuff member are permenantly located substantially adjacent to each other with respect to said tubular base member; (K) Whereby, with deflation of said middle cuff member, a continuous flow of fluid may be fed past a body passage portion between said proximal and distal cuff members via said first and fifth passage means.
