2-piece inflatable implant

A 2-piece inflatable penile implant is a surgically implanted penile prosthesis used to provide reliable erections for men with erectile dysfunction that does not respond adequately to medications or other conservative treatments. The system consists of two inflatable cylinders placed inside the corpora cavernosa and a connected pump positioned in the scrotum, with the fluid reservoir incorporated into the cylinders rather than placed separately in the abdomen or pelvis. This eliminates the separate reservoir required by a 3-piece prosthesis while providing an inflatable alternative with better concealability than a permanently semi-rigid malleable implant.

Advantages

+Provides an inflatable erection : The patient can increase penile rigidity for intercourse and reduce rigidity afterward.
+Better concealability than a malleable implant : Deflation allows a softer resting state than continuously semi-rigid rods.
+No separate abdominal or pelvic reservoir : The integrated fluid-storage design eliminates reservoir placement.
+Useful in selected patients with challenging pelvic anatomy : Avoiding a separate reservoir can be advantageous after certain pelvic or abdominal procedures.
+Fewer components than a 3-piece prosthesis : The system eliminates one major prosthetic component and its associated reservoir-placement step.
+Provides reliable mechanical rigidity : The implant bypasses vascular erectile dysfunction and creates rigidity mechanically.
+Can be revised or converted : Selected patients can later undergo replacement or conversion to another prosthesis type when necessary.

Trade-offs

−Requires operation of a scrotal pump : Patients need adequate hand strength and dexterity to inflate and deflate the prosthesis.
−Usually less natural flaccidity than a 3-piece implant : Integrated fluid storage can limit how completely the cylinders collapse in the resting state.
−Expansion may be less than with contemporary 3-piece systems : Three-piece implants generally offer greater hydraulic expansion and erection/flaccidity differentiation.
−Risk of infection Deep prosthetic infection : can require device removal or salvage surgery.
−Risk of mechanical failure : Pump, cylinder, valve, or hydraulic problems can eventually require revision.
−Risk of erosion : Prosthetic cylinders can erode through corporal, urethral, or distal penile tissues.
−Risk of pump-related problems : Pump malposition, discomfort, scar fixation, or difficulty operating the mechanism can occur.
−Risk of corporal perforation : Dilation and cylinder insertion can damage corporal tissue, particularly in complex or fibrotic anatomy.
−Does not guarantee increased penile length : The cylinders must be safely sized according to the patient's existing corporal dimensions.
−Less commonly used than 3-piece systems in many contemporary practices : Its specific advantages are most relevant to selected patients rather than making it the default inflatable prosthesis.

Mentor GFS™

Mentor Corporation

The Mentor GFS is a discontinued device with no active manufacturer warranty, replacement programme or spare parts. Mentor Corporation's urology business was acquired by Coloplast in 2006 and the GFS line was not continued. Men with an existing GFS who require device removal or exchange are treated under standard revision penile prosthesis surgery pathways, and all costs are quoted as revision surgery.

The Mentor GFS was a two-piece inflatable penile prosthesis introduced in 1988 for the surgical treatment of severe erectile dysfunction. Its defining feature was the elimination of the separate abdominal reservoir: the pump and fluid reservoir were combined into a single scrotal unit known as a resipump, connected by tubing to two inflatable penile cylinders. A revised version, the GFS Mark II, removed the tubing connectors to improve reliability. Neither model is manufactured today. This page is intended primarily for men who already have a Mentor GFS or Mark II implanted and are considering revision, replacement or conversion to a modern device.

Two-piece inflatable design — Paired cylinders plus a single combined scrotal unit; no abdominal or pelvic reservoir.
Resipump — Combined the intra-abdominal reservoir and the scrotal pump into one scrotal component.
Fixed-girth expansion — Cylinders expanded to a predetermined girth and were available in two widths.
Office-adjustable fluid volume — Saline could be added through the resipump as an office procedure.
Connectorless Mark II revision — The Mark II removed the need for tubing connectors.
No surface antibiotic or hydrophilic coating — Predates both technologies.
Discontinued — Not manufactured, not supplied, no parts, no warranty.

Mentor Mark II

Mentor Corporation

The Mentor Mark II is a discontinued device with no active manufacturer warranty, replacement programme or spare parts. Mentor Corporation's urology business was acquired by Coloplast in 2006 and the two-piece line was not continued. Men with an existing Mark II who require device removal or exchange are treated under standard revision penile prosthesis surgery pathways, and all costs are quoted as revision surgery.

The Mentor Mark II was the second-generation version of the Mentor GFS two-piece inflatable penile prosthesis. Its defining change was the removal of the tubing connectors used in the original design, producing a connectorless system intended to be more reliable. Like the GFS, it used paired inflatable cylinders linked to a 25 mL scrotal component that acted as both pump and reservoir, eliminating the separate abdominal reservoir of a three-piece implant. Short-term studies were encouraging, but longer-term data showed the lowest device survival of any multicomponent inflatable prosthesis it was compared against. The Mark II is no longer manufactured. This page is written for men who already have one implanted.

Connectorless two-piece design — The defining change from the original GFS.
25 mL scrotal resipump — Combined pump and reservoir in a single scrotal component.
No abdominal or pelvic reservoir — Simplified surgical anatomy compared with three-piece devices.
Fixed-girth cylinders in two widths — Expansion limited to a predetermined girth.
Office-adjustable fluid volume — Saline could be added through the resipump as an office procedure.
No antibiotic or hydrophilic coating — Predates both technologies.

malleable penile implant

A malleable penile implant is a surgically implanted penile prosthesis used primarily to provide reliable rigidity for men with erectile dysfunction that does not respond adequately to medications, injections, vacuum devices, or other conservative treatments. The device consists of two bendable semi-rigid rods placed inside the corpora cavernosa, allowing the penis to be manually positioned upward for sexual activity and downward for concealment. Unlike inflatable penile prostheses, malleable implants contain no pump or fluid reservoir, making them mechanically simpler and particularly useful for patients who prioritize ease of use, have limited hand dexterity, or require selected prosthesis salvage or reconstructive procedures.

Advantages

+Simplest penile implant, with no pump, tubing or reservoir
+Significantly lower mechanical failure rate than inflatable implants
+No abdominal reservoir, so no risk of reservoir herniation or erosion into nearby organs
+No manual dexterity needed — you bend the rods rather than operate a pump
+Shorter, simpler operation than a three-piece inflatable
+High-bend rods allow a smaller incision in the corpora, which shortens closure time
+Suits heavily scarred or fibrotic tissue where a bulkier device is hard to place
+Costs considerably less than an inflatable device
+Three-year survival free of revision reported at 99.2% for the newest device across 605 patients
+Modern malleable devices carry hydrophilic coatings
+Useful where an implant is also needed to hold a condom catheter, with satisfaction of 86.5–92.8% reported in that group

Trade-offs

−Concealment is difficult — the penis stays semi-rigid at all times
−Higher risk of erosion than inflatable implants
−Significantly lower patient satisfaction than inflatable implants (odds ratio 3.39 favouring inflatable)
−Significantly lower partner satisfaction (odds ratio 2.32 favouring inflatable)
−No infection advantage — infection rates do not differ significantly from inflatable devices
−No girth expansion; the penis does not widen as it would with an inflatable device
−Permanent and irreversible — erectile tissue is destroyed, and tablets or injections will not work if the device is removed
−Adds no length, and does not restore length already lost
−In one cohort of men with prior radical pelvic surgery, complications reached 28.1% with malleable implants versus 3.9% with inflatable
−Erosion was the leading reason for device removal in that series, at 6.1%
−Accounts for under 20% of implants in Europe and the USA, reflecting surgeon and patient preference
−Long-term data on the newest devices is still limited
