Abstract
Official abstract text for this publication.
A needleless injector including a body at a proximal end, a shaft extending distally from the body, at least one injection orifice at a distal end of the shaft in fluid communication with a fluid chamber at the proximal end, a pressure source in communication with the fluid chamber, and a tissue tensioner located at the distal end of the shaft proximal to the injection orifice, wherein the distal end including the tissue tensioner and injection orifice is positionable within a urethral lumen so that when the tissue tensioner is deployed, tissue of the urethra is tensioned at a location for injection of fluid from the injection orifice into the tissue of the urethra.
First claim
Opening claim text (preview).
The invention claimed is: 1. A needleless injector comprising: a body at a proximal end; a shaft extending distally from the body, the shaft comprising an outer surface extending along its length; at least one injection orifice at a distal end of the shaft in fluid communication with a fluid chamber at the proximal end through a fluid channel that extends along a longitudinal axis of the shaft, wherein the at least one injection orifice extends in an injection direction from t…
