Abstract
Occlusion devices and delivery systems are described in which a polymerizing oil is used to protect a hydrogel from premature swelling. In an embodiment, a delivery system includes an occlusion device releasably coupled within a catheter sheath. The occlusion device includes an expandable implant and a hydrogel. An at least partially oxidized polymerizing oil is inside a lumen of the catheter sheath between the distal end of the catheter sheath and the hydrogel.
Claims16
A delivery system comprising:
- a catheter sheath having a distal end, a proximal end, and a lumen therebetween;
- an occlusion device releasable coupled within the catheter sheath, the collusion device comprising an expandable implant and a hydrogel on the expandable implant;
- a polymerizing oil inside the lumen of the catheter sheath between the distal end of the catheter sheath and the hydrogel, wherein the polymerizing oil is at least partially oxidized.
