Thin film vessel occlusion device
First Claim
Patent Images
1. A vessel occlusion device comprising:
- an elongate shaft having a proximal region, a distal region, and a distal end; and
a single layer non-porous metal thin film restriction member having a proximal end and a distal major opening, the proximal end of the restriction member attached to the shaft proximally of the distal end with the distal major opening facing the distal end of the shaft;
the restriction member moveable between a collapsed configuration and a radially expanded frustoconical configuration, wherein the single layer restriction member is impervious to fluid flow.

12. A vessel occlusion device comprising:
-
an elongate tubular shaft having a proximal end and a distal end and a lumen extending therethrough;
a collapsible metal thin film restriction member having a proximal end and a distal major opening, the proximal end attached to the distal end of the shaft such that the distal major opening of the restriction member extends beyond the distal end of the shaft, the collapsible metal thin film restriction member moving between a collapsed configuration and a radially expanded configuration; and
an actuator disposed within the tubular shaft, the actuator moving the restriction member between the collapsed and radially expanded configurations. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of treating a target site in a body conduit while temporarily occluding the conduit, the method comprising:
-
providing a restriction device having a single layer non-porous metal thin film restriction member in a collapsed configuration on a shaft, the restriction member actuatable between a collapsed configuration and a radially expanded configuration;
advancing the restriction device to a desired location either proximal or distal of the target site in the body conduit;
actuating the restriction member from the collapsed configuration to the expanded configuration to occlude the body conduit;
treating the target site;
collapsing the restriction member; and
withdrawing the restriction device from the body conduit. - View Dependent Claims (24, 25, 26)
