Abstract
Devices, systems, and methods used to seal a treatment area to prevent embolic agents from migrating are described. The concept has particular benefit in allowing liquid embolic to be used with a variety of intravascular therapeutic applications, including for occluding aneurysms and arteriovenous malformations in the neurovasculature.
Claims20
A catheter, comprising:
- a catheter body;
- a heater at a proximal end of a distal region of the catheter body;
- and
- a radially expandable shield coupled to the distal region of the catheter body, wherein activation of the heater decouples a portion of the shield from the catheter body.

A catheter, comprising:
- a catheter body having a liquid embolic agent delivery passage;
- a heater at a proximal end of a distal region of the catheter body;
- and
- a radially expandable shield coupled to the distal region of the catheter body, wherein activation of the heater generates heat that decouples a portion of the shield from the catheter body.
1 more element
A catheter, comprising:
- a catheter body;
- a means for generating heat;
- and
- a shield means for blocking liquid embolic agent, the shield means being coupled to the catheter body and being at least partially released from the catheter body when activating the means for generating heat.
