Abstract
Official abstract text for this publication.
The present invention improves significantly the success rate of lithotripsy and reduces the risk of tissue damage, by injecting a temporary plug in front, and optionally behind a concretion (for extracorporeal lithotripsy) or behind a concretion (for intracorporeal lithotripsy). One aspect of the present invention relates to injecting an inverse thermosensitive polymer solution into a lumen, thereby preventing the migration of a concretion, or its fragments, upon extracorporeal or intracorporeal lithotripsy.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of mitigating risk of damage to surrounding body tissue during lithotripsy on a concretion located in a lumen of the body, the method comprising: introducing a solution comprising purified inverse thermosensitive polymer at a location distal to the concretion in the lumen; forming a temporary plug in the lumen distal to the concretion by gellation of the solution; deploying an energy source proximate to the concretion; and applying energy to t…
