Physician and patient satisfaction with the new AMS 700 momentary squeeze inflatable penile prosthesis.
BACKGROUND
A single-armed, prospective, multicenter study evaluated the redesigned American Medical Systems (AMS) 700 Momentary Squeeze (MS) pump inflatable penile prosthesis (IPP) with enhanced features for ease of implantation and patient manipulation. The device incorporates design changes to all components: pump, cylinders, rear-tip extenders, and reservoir.


OBJECTIVE
To assess physician and patient satisfaction with the new AMS 700 MS pump.


METHODS
Patients were selected from the existing population experiencing erectile dysfunction (ED) without previous prosthetic implantation.


METHODS
Survey questionnaires were used to capture physician feedback on ease of implantation and patient education. Patient satisfaction with the device and existence of autoinflation were assayed.


RESULTS
Sixty-nine patients were implanted at seven U.S. sites. Mean age was 60.1 +/- 9.6 years. History of ED was >5 years in 34 (44.7%) patients. Main ED etiology was organic, nonspecific (32%). Eighty-four percent of the physicians felt proximal cylinder insertion was easier because of the smaller angle of cylinder input tubing and narrower base diameter. The new pump was felt easier to implant than the previous model by 57% of the physicians. The patients found the manipulation of the pump simple at device activation, with 96% easily locating the inflation bulb and 94% deflating the device with one push of the deflation button. Reviews were mixed among physicians concerning ease of training compared with the Tactile pump. Patient training was easier in 71%, harder in 21%, and same in 8%. Nevertheless, 67% of the patients were trained in 6 minutes or less. At 6 months, 77% of the patients were very satisfied, 9% somewhat satisfied, and 14% dissatisfied. Autoinflation occurred in two patients (3%).


CONCLUSIONS
The new AMS 700 MS IPP seems a distinct improvement over previous devices with most physicians feeling implantation and patient instruction were easier. The device also satisfied 86% of the users and virtually eliminated autoinflation.
