Abstract

Polymer particle embolics and methods of making same are described. The particle embolics can be used as embolization agents.

Claims (30)

1. A polymer particle comprising:

poly(ethylene glycol) diacrylamide, glycerol monomethacrylate, and amino ethyl methacrylate;

wherein the polymer particle is spherical and has a diameter less than about 1,200 μm.

2. The polymer particle of claim 1 , wherein the polymer particle has a diameter between about 40 μm and about 1,200 μm.

3. The polymer particle of claim 1 , further comprising N,N-methylenebisacrylamide.

4. The polymer particle of claim 1 , wherein the N,N-methylenebisacrylamide is at a concentration of about 1% w/w.

5. The polymer particle of claim 1 , wherein the poly(ethylene glycol) diacrylamide is at a concentration of about 28% w/w.

6. The polymer particle of claim 1 , wherein the glycerol monomethacrylate is present at a concentration of about 68% w/w.

7. The polymer particle of claim 1 , wherein the amino ethyl methacrylate at a concentration of about 3% w/w.
