First Claim
Patent Images
1. A vascular catheter, comprising:
- a generally cylindrical tubing comprising a distal end and defining at least one lumen, said tubing defining a portal located on a side of said tubing, said portal comprising an axially oriented opening having a distal end and an axially oriented slit having a proximal end in communication with said opening, said axially oriented slit extending from said distal end of said opening toward said distal end of said tubing, said proximal end of said slit expandable from a closed position to an open position.

Abstract
A dual lumen vascular catheter with expanding side portal includes a cylindrical tubing with one or more lumens inside. An effusion portal is located on the side of the tubing at an end of one lumen. The portal is oval-shaped, with an open-ended slit connected to an end of the oval opening. The slit is thereby expandable, allowing for vacuum relief during aspiration of blood in the event that the catheter is lodged with the portal pressed against an inner wall of the vein.
