Arterial graft device
First Claim
Patent Images
1. An arterial graft device for reinforcing bifurcated arteries having a distal main artery portion and two proximal legs extending from a bifurcation, the arterial graft device comprising a body adapted for at least partial placement in the main artery portion and a separate elongated segment, the body including:
- (a) an integral elongated segment extending proximally from a bifurcated juncture to a first of the two legs to internally connect the main artery portion with the first leg; and
(b) a second segment extending proximally from the bifurcated juncture towards the second leg and comprising;
(i) a first diameter at said bifurcated juncture (ii) a connecting portion comprising a second diameter, smaller than said first diameter, proximal said first diameter and adapted to mate with said separate elongated segment, and (iii) a guide wire and second segment receiving portion, proximal said connecting portion and of larger diameter than said connecting portion, and a conical transition section between said connecting portion and said larger diameter.

Abstract
An arterial graft device and a process for positioning the same, wherein the device provides a first part positioned by conventional techniques within the artery, and a second part which is positioned and fixed on the first part by a segment which is provided on the first part so as to prevent a catheter guidewire—whereby the second part is positioned in place—from deviating and damaging arterial walls.

9. An arterial graft device for reinforcing bifurcated arteries having a distal main artery portion and two proximal legs extending from a bifurcation, the arterial graft device comprising a body adapted for at least partial placement in the main artery portion and a separate elongated segment, the body including:
- (a) an integral elongated segment extending proximally from a bifurcated juncture to a first of the two legs to internally connect the main artery portion with the first leg; and
(b) a second segment having a connecting opening and extending towards the second leg and having a connecting surface of distally increasing diameter as the second segment extends from the connecting opening towards the bifurcated juncture and of proximally increasing diameter as the second segment extends from the connecting opening towards the second leg for receiving and guiding a catheter guidewire inserted along the second leg and for guiding the separate elongated segment of the graft device for connection with the second segment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
