Evaluation of the Rigicon Infla10® Inflatable Penile Prosthesis (IPP) for Erectile Dysfunction

Evaluation of the Rigicon Infla10® Inflatable Penile Prosthesis (IPP) A Prospective, Multicenter, Single-Arm Performance-Goal Study

This study evaluates the long-term safety and effectiveness of the Rigicon Infla10® Inflatable Penile Prosthesis in patients with erectile dysfunction. The study follows patients implanted with the Rigicon Infla10® Pulse™ Dynamic Inflatable Penile Prosthesis for up to 3 years after implantation.

Erectile dysfunction (ED) is a common male sexual dysfunction associated with a reduced quality of life for patients and their partners. Incidence of ED increases with age and is associated with depression, obesity, diabetes mellitus, hypertension, cardiovascular disease and benign prostatic hyperplasia. ED is diagnosed with symptoms of (1) inability to attain or sustain a penile erection during sexual activity and (2) a reduction of penile rigidity in >75% of sexual encounters during six months period. ED is estimated to affect approximately 52% of men in age of 40 to 70 years. It is projected in 2025, the worldwide ED prevalence of about 322 million. ED usually has organic causes, such as damage of arteries, smooth muscle and fibrous tissue. This results in impairment of blood flow to and from penis due to diabetes, renal disease, atherosclerosis and vascular disease.

Management of ED involves lifestyle modification, medical, surgical interventions, and possibly, in the future, tissue- engineering or cellular or gene therapy. Oral phosphodiesterase type 5 inhibitor (PDE5i), which works with sexual stimulation, is an effective medical therapy for ED with an excellent safety profile. Intracavernosal injection or topical application of vasoactive drugs have also been studied. The first inflatable penile prosthesis was introduced in 1973, and current models of inflatable penile prostheses include the AMS 700 series, and Coloplast Titan device. A patient-activated inflatable penile prosthesis (IPP) provides patients with a means to achieve dependable spontaneity for intercourse.

Rigicon has developed a three-piece inflatable penile prosthesis (IPP) (Infla10®) for the treatment of ED. This study is to assess the safety and effectiveness of the Rigicon IPP in treating ED. Clinical literature and preclinical testing, including biocompatibility, device validation and verification, and animal studies support the safety and efficacy of this device for the intended therapy.
