Methods for Preventing Retropulsion of Concretions and Fragments During Lithotripsy
First Claim
1. A method of lithotripsy, comprising the steps of:
- injecting a first composition into a lumen of a mammal distal to a concretion;
thereby forming a polymer plug; and
directing energy to said concretion causing the fragmentation of said concretion into a plurality of fragments.

Abstract
One aspect of the present invention provides a method for the treatment of lithiasis, which mitigates the risk of damage to surrounding body tissue when removing a calculi (e.g., biological concretions, such as urinary, biliary, and pancreatic stones) that obstructs or may otherwise be present within a body'"'"'s anatomical lumen. In one embodiment, the instant invention provides a method of using a polymer plug to occlude a lumen distal to a calculi, whereby calculi fragments resulting from lithotripsy are prevented from traveling up the lumen. In certain embodiments, a dual lumen catheter is utilized to inject two solutions proximal to the calculi, the mixing of said solutions causing a polymer plug to form.
