Rigi10™ Malleable Penile Prosthesis
Also Known As
IPP, Hydraulic Penile Implant, Inflatable Penile Implant, Three-Piece Penile Prosthesis, Pump-Activated Penile Device
Definition
An Inflatable Penile Prosthesis (IPP) is a surgically implanted medical device designed to treat erectile dysfunction (ED) by enabling men to achieve an erection sufficient for sexual intercourse. The device consists of paired cylinders implanted in the corpora cavernosa of the penis, a pump placed in the scrotum, and a fluid reservoir positioned in the lower abdomen. When activated by the patient, fluid from the reservoir is transferred to the cylinders via the pump, creating an erection. The device remains deflated when not in use, providing a natural appearance, and can be deflated after sexual activity by activating the release mechanism in the pump.
The IPP offers advantages over non-inflatable (malleable) implants, including a more natural erection, better flaccid state concealment, and greater rigidity. Modern devices typically feature antibiotic coatings to reduce infection risk and specialized cylinder materials to enhance durability and performance.
Clinical Context
Inflatable penile prostheses are typically reserved for patients with erectile dysfunction who have failed or are not candidates for less invasive treatments such as PDE5 inhibitors (e.g., sildenafil), vacuum erection devices, or intracavernosal injections.
Key clinical considerations include patient selection, preoperative counseling, and surgical technique. Candidates should have reasonable expectations and manual dexterity to operate the device. The procedure is generally contraindicated in patients with active infections, uncontrolled diabetes, or certain psychological conditions.
Surgical outcomes are favorable, with satisfaction rates ranging from 85-95% for both patients and partners. Modern devices have a mechanical reliability rate exceeding 90% at 5 years post-implantation. Potential complications include infection (1-3%), mechanical failure, device erosion, or improper sizing. Antibiotic-impregnated and hydrophilic-coated implants have significantly reduced infection rates compared to earlier generations of devices.
The surgical approach typically involves either penoscrotal or infrapubic incision, with the choice dependent on surgeon preference and patient anatomy. Recovery generally requires 4-6 weeks before device activation, with most patients returning to normal activities within 2-3 weeks post-surgery.
