Abstract

See full text

A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a 'T' with the top of the 'T' implanted within the lumen of or anastomotically attached to a vascular structure. The lumen of the implanted portion of the catheter completely occupies or may be aligned with the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the 'T' of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter. The leg of the 'T' may be connected to the side wall of the implant portion of the catheter at an angle, such that the axis of the lumen of the leg of the 'T' intersects the axis of the lumen of the implanted portion of the catheter at approximately a 45.degree. angle.
