Document Type and Number:
WIPO Patent Application WO2002049537
Kind Code:
A8
Abstract:
The present invention is a percutaneous catheter assembly intended for long-term blood flow of several days, said assembly comprising generally three components: a catheter housing having three sections, each of preferably differing diameter, with a set of perforations in a distal section, an end cap for closing off a proximal end of the catheter housing during insertion, and a dilator having an outer diameter substantially the same size as the inner diameter of the smallest section of the catheter housing, the dilator being configured to pass radiopaque contrast through a first and second set of openings in the dilator and the perforations in the catheter housing. The present invention further comprises a method of percutaneous blood perfusion in which the catheter assembly is used without the need for an introducer sheath.
