Abstract:
1. A catheter comprising: a distal shaft having a length, a substantially constant outer diameter along a majority of its length, a lumen and a proximal end; a proximal shaft having a length, a substantially constant outer diameter along a majority of its length, a wall defining an inner lumen and a distal end, the distal end of the proximal shaft being connected to the proximal end of the distal shaft and the lumens of the respective shafts being in fluid communication with one another; a heat shrinkable sleeve having a longitudinal length extending from a proximal-most end to a distal-most end of said heat shrinkable sleeve, and overlapping the proximal end of the distal shaft and the distal end of the proximal shaft providing a water seal, wherein said longitudinal length consists of a small portion of the distal end of the proximal shaft and a small portion of the proximal end of the distal shaft; and a port, wherein the port is positioned between the first and second ends of the heat shrinkable sleeve and formed at least partially transversely through the wall of the proximal shaft, wherein the catheter is sterilized and prepared to safely enter a body.
