First Claim
Patent Images
1. A vaso-occlusive device for implantation into the vasculature of a patient comprising:
- at least one polymer capable of taking a form that can pass through a delivery device to a site of abnormal blood flow, whereupon the at least one polymer assumes a vaso-occluding shape at the site.

Abstract
Methods and apparatus usable for performing vaso-occlusion at a site of abnormal blood flow in the body. The methods typically comprise treatments for occluding abnormal blood flow in the body, and can be applied to treatment for aneurysms, AVMs, fistulas, ruptured blood vessels and benign or malignant tumors.

-
17. A method of making a vaso-occlusive device for implantation into the vasculature of a patient comprising:
-
contacting at least one polymer, copolymer or blended polymer to form a pre-implantation hydrogel polymer, and hydrating the hydrogel polymer either before or during implantation into the patient through a delivery device.

-
23. A method of treating a patient having abnormal blood flow comprising:
implanting in the patient at the site of the abnormal blood flow a device comprising at least one polymer capable of being delivered through a delivery device to an implantation site comprising abnormal blood flow in a patient, whereupon after implantation of the device in the patient the device forms a vaso-occlusive shape.
