Abstract:
A shunt device for implantation in a fluid-carrying vessel or tubular tissue structure, comprising: an elastically deformable, generally tubular body, said tubular body having upper and lower opposing wall portions, a central portion and first and second end portions, said first and second end portions having a relatively larger circumference than said central portion, wherein said lower wall portion extends substantially linearly along said tubular body and said upper wall portion includes first and second tapered wall sections that together define a recessed section of said upper wall portion, said first tapered wall section extends between said first end portion and said central portion and said second tapered wall section extends between said second end portion and said central portion, and said central portion and said first and second end portions collectively define a longitudinal axis whereby stretching at least one end portion along said longitudinal axis, during implantation or delivery of said tubular body, results in a reduction in a dimension of said tubular body which is transverse to said longitudinal axis; and means for facilitating the insertion and position of said shunt device within a vessel or tubular structure.
