Abstract:
An apparatus for forming an occlusion within a body cavity comprising:a catheter;a wire; anda detachable elongate tip portion coupled to a distal portion of said wire which is retrievable until detached, said tip portion being adapted to be positioned in said body cavity to form an occlusion in said body cavity using one or more implantations of detachable elongate tip portions from corresponding wires, said wire having a radioopaque marker disposed thereon proximal on said wire from a detachment point of said elongate tip portion from said wire by a predetermined distance, said catheter having two radioopaque markers disposed thereon and spaced apart from each other, wherein one of said two markers on said catheter is provided at a distal end of said catheter and said other marker is positioned proximally thereof,wherein said radioopaque markers are disposed on said wire and said catheter so that when said marker at said distal end of said catheter is disposed adjacent to an opening of said body cavity and when said wire is telescopically disposed in said catheter to approximately align said wire's radioopaque marker with said more proximal catheter marker, said detachable elongate tip portion then is fully disposed in said body cavity.
