SYSTEMS AND METHODS FOR DEPLOYING DEVICES TO GENITOURINARY SITES

摘要

A method delivers an implantable device through the urethra and into the bladder. A deployment instrument is inserted into the urethra, the implantable device is inserted into the deployment instrument, and a stream of fluid is injected into the deployment instrument. The stream of fluid drives the implantable device from the deployment instrument into the bladder. The deployment instrument is removed from the urethra, leaving the implantable device wholly implanted in the bladder.

1. A system for deploying a medical device into a urinary bladder of a patient, the system comprising:
a deployment catheter configured for traversing a urethra of the patient to reach the bladder, the deployment catheter comprising a distal end portion comprising a coude tip, a closed distal end, and an exit opening defined in a sidewall of the distal end portion, and an internal lumen curved to terminate at the exit opening and configured for receiving the medical device therein; and a stylet removably received within the internal lumen of the deployment catheter and configured for driving the medical device out of the internal lumen of the deployment catheter and into the bladder, the stylet comprising an internal lumen extending from a proximal end to a distal end of the stylet, the internal lumen of the stylet in fluid communication with the internal lumen of the deployment catheter.
