ABSTRACT:
A surgical apparatus for the placement of an instrument within a body cavity which comprises a placement device including an elongate element with an exposable tissue piercing tip, a first coupling means adjacent to the tip, and means for selectively exposing the tip; and an elongate instrument for placement including a second coupling means adapted to be coupled to the first coupling means to effect an end to end coupling of said device and said instrument whereby said instrument is positioned within said body cavity. Preferably the instrument is a suprapubic instrument for placement within a bladder. A method for placement of a suprapubic instrument is also disclosed. Also shown is a method and apparatus for end-to-end instrument coupling in the context of guidewire instrument placement. End-to-end coupling is accomplished by loop and slot arrangements, a tail and collapsing loop arrangement, and a tail captured between two slidably disposed sleeves.
