Abstract
A catheter has a distal end which is to be positioned through potentially contaminated tissue within a patient to a desired site, and a proximal end. The catheter has at least one fluid lumen extending between the distal end and the proximal end. The fluid lumen provides fluid communication between the desired site and the proximal end. A removable protective barrier is positioned within the fluid lumen at its distal end. The protective barrier is made from a biocompatible material and selectively occludes the distal end of the fluid lumen so that entry of the contaminated tissue, prior to the distal end of the catheter reaching the desired site, is prevented.
Claims20
A catheter which is to be atraumatically advanced through potentially contaminated material within a body lumen of a patient to a desired site, said catheter having distal and proximal ends and comprising:
- a fluid lumen extending between said distal end and said proximal end, said fluid lumen having a distal facing opening at said distal end and providing fluid communication between said site and said proximal end when said distal end is at said site, said distal end of said catheter being blunt;
- and
- a removable protective barrier positioned across said distal facing opening of said fluid lumen at said distal end, said protective barrier being made from a bio-compatible material and occluding said distal end of said fluid lumen thereby preventing entry of said contaminated material prior to said distal end of said catheter reaching said desired site, said protective barrier being selectively removable by fluid pressure in said lumen exceeding a predetermined level, said protective barrier being blunt.
