Method and apparatus for placement of implantable device adjacent a body lumen
First Claim
1. A method of positioning and implanting an expandable implantable device at a target site for controllable coaptation of a male patient'"'"'s urethra using a biplanar ultrasonic probe inserted into a rectum of the patient, comprising:
- inserting a Foley catheter into the urethra;
expanding a Foley balloon in the bladder neck;
inserting the ultrasonic probe into the rectum of the patient;
using the ultrasonic probe to image the urethra and Foley balloon at the bladder neck;
placing a small puncture in the perineum;
passing a delivery device through the puncture to the target site with concurrent delivery of a local anesthetic under guidance of the ultrasonic probe and positioning the delivery device at the target site, using radial and longitudinal views provided by the ultrasonic probe, wherein the target site is proximal to the apex of the prostate or an urethral vesical anastomosis;
expanding the target site using fluid delivered from the delivery device;
delivering the expandable implantable device to the expanded target site; and
adjusting the expandable implantable device to improve coaptation of the urethra,wherein the amount of the expansion of the expandable implantable device controls the coaptation of the urethra.

Abstract
The present subject matter provides method and apparatus for placement of implantable devices adjacent a body lumen. A method of implanting an implantable device at a target site for controllable coaptation of a patient'"'"'s urethra using an ultrasonic probe inserted into a rectum of the patient comprises inserting a Foley catheter into the urethra, expanding a Foley balloon in the bladder neck, inserting the ultrasonic probe into the rectum of the patient, using the ultrasonic probe to image the urethra and Foley balloon at the bladder neck, placing a small puncture in the perineum, passing a delivery device to the target site under ultra sonic guidance, injecting echogenic fluid at the target site adjacent the urethra, delivering the implantable device to the target site, and adjusting the implantable device to improve coaptation of the urethra.

23. A method of positioning and implanting an expandable implantable device at a target site for controllable coaptation of a patient'"'"'s urethra using a biplanar ultrasonic probe inserted into a rectum of the patient, comprising:
-
providing a patient having a Foley catheter in the urethra with a Foley balloon expanded in the bladder neck, a biplanar ultrasonic probe in the rectum, and a puncture in the perineum; passing a delivery device through the puncture in the perineum of the patient towards a target site and positioning the delivery device at the target site, under guidance of the ultrasonic probe using radial and longitudinal views provided by the ultrasonic probe, wherein the delivery device delivers an echogenic fluid having a local anesthesic along the passage; expanding the target site using hydrodissection; delivering the expandable implantable device to the expanded target site; and adjusting the expandable implantable device to improve coaptation of the urethra, wherein the amount of the expansion of the expandable implantable device controls the coaptation of the urethra.
