Conditions

Urinary Stone

Brief summary

This is a single arm, single center study to assess the safety and efficacy of a form of extracorporeal lithotripsy, called the Enhanced Lithotripsy System, to treat urinary stones.

Detailed description

This is a single arm, single center study to assess the safety and efficacy of a form of extracorporeal lithotripsy, called the Enhanced Lithotripsy System, to treat urinary stones. Subjects will be treated up to 2 times with the Enhanced Lithotripsy System and followed for 30 days after the last treatment session.

Interventions

The Enhanced Lithotripsy System is a type of lithotripsy system comprising a console, treatment head, and Acoustic Energy Focusing material. Operation of the Enhanced Lithotripsy System entails combined action of extracorporeal insonation and Acoustic Energy Focusing material to fragment urinary stones.
