The Coloplast Titan inflatable penile prosthesis (IPP) was recently The Coloplast Titan inflatable penile prosthesis (IPP) was recently modified with a One Touch Release (OTR) pump, to facilitate modified with a One Touch Release (OTR) pump, to facilitate deflationdeflation
The OTR pump became available in September of 2008The OTR pump became available in September of 2008 OTR pumps are now available as separate units, or pre-connected OTR pumps are now available as separate units, or pre-connected
to cylindersto cylinders The The objectivesobjectives of this investigation were to assess the ease of of this investigation were to assess the ease of
implantation of this new pump, and to assess it’s functionality and implantation of this new pump, and to assess it’s functionality and ease of patient use, compared to the prior (Genesis) pump.ease of patient use, compared to the prior (Genesis) pump.

Conclusions Conclusions
With short term follow-up:With short term follow-up: OTR pump functioned as specified by the manufacturerOTR pump functioned as specified by the manufacturer No instance of OTR pump malfunctionNo instance of OTR pump malfunction OTR pump resulted in a statistically significant reduction in the OTR pump resulted in a statistically significant reduction in the
