Abstract
A method of treating a prostate condition, including the steps of providing a needleless injector that includes a body at a proximal end, an injection shaft extending from the body to a distal end of the injection shaft, an injection orifice at the distal end of the injection shaft and positioned for fluid ejection in a lateral direction relative to a longitudinal axis of the injection shaft, a pressure source in communication with the fluid chamber, and an extendable tissue tensioner located at the distal end of the injection shaft proximal to the injection orifice; inserting the injection shaft into a urethra so the injection orifice is located within the prostatic urethra; actuating the tissue tensioner to contact urethral tissue, and injecting fluid from the injection orifice into the prostate.
