Catheter and tunneling device therefor
First Claim
1. A tunneling device for use in inserting a catheter, comprising:
- a relatively rigid member having a handle and an end configured with an elongated groove which extends radially inwardly from an outer surface of said rigid member and runs substantially lengthwise such that the groove is exposed and continuous and configured to laterally receive said catheter, wherein said groove further includes two separate channels forming a Y-shaped mid-section to receive at least part of a Y-shaped end of the catheter, wherein said end of said tunneling device is equipped with a hollow cap removably connected to a tip of said end of said tunneling device to receive a first end of said catheter and cover openings of the first end of the catheter in a manner to maintain the openings substantially covered during insertion of the catheter into a the body thereby preventing potential clogging thereof by tissue and blood and removed post insertion while the tunneling device remains in the body.

Abstract
A catheter for introduction and removal of fluids from a body and tunneling device therefor, the catheter has a body having a first conduit for removing fluid from the body and a second conduit for delivering fluid to the body wherein at least a part of each of the conduits is integrally formed within a first end of the body of the catheter and extends along side one another. The first conduit extends beyond the second conduit and forms a terminal point of the first end and defines a first opening thereat and the second conduit extends to a point short of the terminal point defining a second opening. A bumper portion is adjacent the second opening extending toward the terminal point. Another part of each the first and the second conduits are disjoined and form part of a second Y-shaped end. The tunneling device has a channel to removably receive the catheter.

4. A method of introducing a catheter into a body, comprising the steps of:
-
a. providing a tunneling device comprising a relatively rigid member having a handle and an end configured with an elongated groove which extends radially inwardly from an outer surface of said rigid member and runs substantially lengthwise such that the groove is exposed and continuous and configured to laterally receive said catheter, wherein said groove further includes two separate channels forming a Y-shaped mid-section to receive at least part of a Y-shaped end of the catheter, wherein said end of said tunneling device is equipped with a removable hollow cap removably connected to a tip of said end of said tunneling device to receive openings of a first end of the catheter in a manner to maintain the openings substantially covered during insertion of the catheter into the body thereby preventing potential clogging thereof by tissue and blood; b. laying the first end of the catheter in the exposed elongated groove in a manner such that the openings of the first end of the catheter are received in the cap of the tunneling device; c. inserting the tunneling device having the catheter therein through a first incision of the body such that the cap extends out a second incision of the body; d. removing the cap post insertion while the tunneling device remains in the body; e. lifting the first end of catheter from the tunneling device; f. removing said catheter from the tunneling device; and g. removing said tunneling device from the body.
