Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
A balloon-catheter with a detachable occlusion member for intravascular and permanent occlusion of vascular connections and cardiac septal defects, the improvement, comprising, a position balloon disposed at the distal end of the catheter the position-balloon being connected to the catheter; an occlusion-balloon detachably mounted on the catheter at a particular distance from the position balloon and rearwardly displaced from the distal end in a direction toward the other end of the catheter; and means for providing for filling and emptying of the balloons so that they can be separately filled and evacuated via separate lumina from the other end of the catheter.
Claim 2
Dependent Claim
102 words
A balloon-catheter with a detachable occlusion member for intravascular and permanent occlusion of vascular connections and cardiac septal defects, the improvement, comprising, a position balloon disposed at the distal end of the catheter the position-balloon being connected to the catheter; an occlusion-balloon detachably mounted on the catheter at a particular distance from the position balloon and rearwardly displaced from the distal end in a direction toward the other end of the catheter; and means for providing for filling and emptying of the balloons so that they can be separately filled and evacuated via separate lumina from the other end of the catheter.
Claim 3
Dependent Claim
31 words
A balloon-catheter according to claim 1, wherein the position-balloon is fixedly attached to the catheter, while the detachable occlusion-balloon can be released by effecting a relative displacement across the evacuated position-balloon.
