First Claim
Patent Images
1. A occlusion catheter system comprising:
- a first catheter member having a first lumen extending longitudinally through the first catheter member and a first opening at a distal end of the first catheter member;
a second catheter member having a second lumen extending longitudinally through the second catheter member and a second opening at a distal end of the second catheter member, the second catheter member is positioned over and in spaced apart relationship relative to a proximal section of the first catheter member forming an annular space between the second catheter member and the first catheter member, the proximal section of the first catheter member resides within the second lumen of the second catheter member and the first catheter member extends beyond the distal end of the second catheter member,a third catheter member having a third lumen extending longitudinally through the third catheter member and a third opening proximate a distal end of the third catheter member;
the third catheter member is positioned over a distal section of the first catheter member, the third catheter member having a distal section that extends distally from a distal end of the first catheter member such that the first lumen and the third lumen are in fluid flow communication, whereby the second and third catheter members are spaced apart from each other along a longitudinal axis of the first catheter member with the first catheter member extending there between;
an atraumatic tip member having a proximal section co-axially coupled proximate to a distal end of the third catheter member; and
an expandable occlusion member coupled to the second catheter member near the distal end of the second catheter member and to the third catheter member near a proximal end of the third catheter member, the expandable occlusion member being positioned such that a space between the distal end of the second catheter member and the proximal end of the third catheter member is within the expandable occlusion member.

Abstract
A low profile occlusion catheter having a guiding atraumatic tip that prevents entry of the balloon into collateral vessels. The occlusion catheter system is particularly well suited for use in vascular occlusion and includes a pressure monitoring line to monitor the degree and state of occlusion.

26. A balloon catheter vascular occlusion system comprising:
-
a first catheter member having a first lumen passing longitudinally through the first catheter member, a first proximal end and a first distal end with a first distal opening; a second catheter member having a second lumen passing longitudinally through the second catheter member, a second proximal end and a second distal end, the second catheter member being joined to the first catheter member near the first and second proximal ends such that the first lumen is positioned substantially co-axial with the second lumen; a third catheter member having a third lumen passing longitudinally therethrough, a third proximal end and a third distal end defining a third distal opening, the third proximal end coupled to the first distal end near the first distal opening such that the first lumen is in fluid communication with the third lumen, an atraumatic tip coupled to the third distal end to close the third distal opening and projecting distally therefrom, the atraumatic tip configured to track along major vessels while preventing entry into collateral vessels; an occlusion balloon having a proximal balloon end and a distal balloon end and being in fluid flow communication with the second lumen of the second catheter member, the proximal balloon end connected to the second distal end and the distal balloon end connected to the third proximal end; and a pressure sensing port extending through at least one of the first catheter member and the third catheter member between the distal balloon end and the atraumatic tip. - View Dependent Claims (31, 33, 36, 37, 38, 39, 40)
