Embolic occlusion of uterine arteries
First Claim
18. A therapeutic procedure for treating a female patient'"'"'s uterine disorder, comprising:
- a. advancing a delivery catheter through the patient'"'"'s vasculature until a distal portion of the catheter is disposed within a desired location of the patient'"'"'s first uterine artery; and
b. injecting a bioabsorbable, short lived embolic material through the delivery catheter into the desired location of the patient'"'"'s first uterine artery to temporarily occlude at least a portion of the patient'"'"'s first uterine artery for a therapeutically effective time period.

Abstract
A treatment procedure is disclosed which involves the short term, non-permanent occlusion of the patient'"'"'s blood vessels by depositing a bioabsorbable embolic mass within the patient'"'"'s blood vessel. The procedure is particularly suitable for treating uterine disorders by occluding a patient'"'"'s uterine arteries. A therapeutically effective time period for occlusion of a uterine artery is from about 0.5 to about 48 hours, preferably about 1 to about 24 hours, with occlusion times of about 1 to about 8 hours being suitable in many instances. The embolic mass may bioabsorbable particulate with minimum transverse dimensions of about 100 to about 2000 micrometers, preferably about 300 to about 1000 micrometers. The particulate may be a polymeric material formed of polylactic acid, polyglycolic acid or copolymers thereof, or a swellable copolymer of lactic acid and polyethylene glycol. The embolic material may be delivered to an intracorporeal site as a biocompatible solution containing a solute which is relatively insoluble in a water based fluid and a solvent which is relatively soluble in the water based fluid, where the solute forms the embolic mass which occludes or partially occludes a body lumen or fills or partially fills a body cavity.
