Abstract
The invention concerns a device for preparing a hollow organ for anastomosis to another hollow organ. The said device comprises an anastomosis prosthesis, deployment apparatus to deliver the said prosthesis to a desired site in the body and a coupling device to secure the said prosthesis to said deployment apparatus during delivery.
Claims24
An instrument for preparing a hollow organ for anastomosis to another hollow organ, comprising:
- (a) an implantable prosthesis with a first tubular member attached to a flat pliable member with an opening, wherein,
- the first tubular member has a first free end and a second end, and,
- the first tubular member and the pliable member are connected such that the luminal surface of the first tubular member is continuous with the far surface of the flat member, and,
- the opening in the flat member matches the cross-sectional area of the lumen of the first tubular member, and,
- (b) an instrument comprising a coupling device for securely holding said prosthesis, and a deployment apparatus for delivering said prosthesis to a desired location, wherein,
- (i) said coupling device comprising a double-walled ring shaped member, a tubing connection assembly, and a first fixation mechanism, wherein,
- 1. said ring shaped member is provided with radial partitions defining a plurality of chambers, with each chamber having a first end and a second end such that, each of said chambers is luminally continuous with all other said chambers, through its said first end, and each of the chambers is open to the atmosphere through its said second end, and,
- 2. the first tubing connection assembly is in fluid connection with all of the said chambers, and,
- 3. the first fixation mechanism allows said ring-shaped member to be fastened to said deployment apparatus, and
- (ii) said deployment apparatus comprising a first tube with a free edge and a coaxial outer second tube with a free edge, a flow control valve, a mechanism for displacing the second tube with respect to the first tube, and a trigger for activating said mechanism, wherein,
- 1. said first tube is provided with a side-arm, said side-arm being luminally continuous with the first tube,
- 2. said second tube is provided with a second fixation mechanism that cooperates with the first fixation mechanism, of the coupling device and,
- 3. said flow control valve has an inlet, a first outlet, a second outlet, and a flow control lever, wherein,
- (α) said inlet is adapted for connection to a suction apparatus, and,
- (β) said first outlet is coupled to the side-arm of the first tube, and,
- (χ) said second outlet is coupled to a fluid connection device, the said fluid connection device being adapted for connection to a the tubing connection assembly.
