ZSI 475 FTM Hydraulic Penile Implant
The
ZSI 475 FTM is the first-ever hydraulic penile implant designed
specifically for trans men!
Made by Zephyr Surgical Implants of Switzerland, the ZSI 475 FTM Hydraulic Penile Implant is designed to provide excellent stability and cosmetic results.
The ZSI 475 FTM is made of NUSIL silicone which is manufactured at a density that is ideal for longterm durability, malleability and providing a lifelike erection. The reinforced nickel-titanium rod interior increases the lifespan of the implant.
Important note: Zephyr penile implants are not available in the USA and ZSI is not currently seeking FDA approval. At this time, they are available in Canada, Cuba and some countries in Europe and South America.
Other features of the ZSI 475 FTM:
- One cylinder instead of two, providing excellent cosmetic results when inflated and deflated.
- Available in three sizes: 120mm, 150mm, 170mm in length.
- A 25mm wide, realistically shaped glans "stopper" is affixed to the tip of the implant. The glans is shaped with a small indentation that serves as a passage for the urethra, easing implantation.
- The proximal part of the implant has a plate made from stainless steel and silicone which is fixed securely to the pubic bone.
The implant functions like other hydraulic implants to obtain an erection:
Studies on the ZSI 475 FTM
The
Frontier of Penile Implants in Phalloplasty: Is the ZSI 475 FTM
what we have been waiting for? [FULL TEXT]
Preto, M., Blecher, G., Timpano, M. et al. Int J Impot Res,
January 2021.
Unfortunately, the perfect prosthesis, particularly in
phalloplasty, eludes us. Ideally it would be completely inert and
remain free from infection. It would also provide perfect rigidity
and stability when erect and be easily incorporated into the
pelvis. It would remain permanently free from mechanical damage
and would never find its way eroding through local tissues. So
what is the reality for trans-males undergoing PP implantation in
a phalloplasty? The incidence of postoperative complications are
dramatically higher in phalloplasty, compared to a native phallus.
While the phalloplasty surgical community has long awaited
dedicated technologies and implants, the ZSI-475 FTM appears to
claim some benefits. However, little can be solidly concluded at
this early stage as we eagerly await further objective, well
planned trials to assess both surgical complications, implant
survival, and patient reported outcomes.
Implantation of the Zephyr ZSI 475 FTM erectile
device in cis- and transmen after phalloplasty: initial
experience and prospective analysis of surgical outcome
Wesley Verla, MD, Dept. of Urology, Ghent University Hospital, AUA
Virtual Conference presentation, May 15, 2020.
46 patients with a median (IQR) age of 35 (27-43) years were
included for analysis, comprising 7 cismen and 39 transmen. Median
(IQR) follow-up was 12 (8-18) months. Postoperative complications
comprised infection of the prosthesis in 5 patients (11%),
prosthesis malpositioning in 2 patients (4.3%), mechanical failure
in 2 patients (4.3%) and distal cilinder protrusion in 1 patient
(2.2%). All complications required revisional surgery.
Implantation of the Zephyr ZSI 475 FTM erectile device in patients
after phalloplasty is feasible and safe. Early surgical outcome is
promising, though future analyses with longer follow-up are
required to confirm these findings.
First Outcomes of the ZSI 475 FtM, a Specific
Prosthesis Designed for Phalloplasty
Paul Neuville, et al. The Journal of Sexual Medicine,
January 2019.
This is the first study to report data on the ZSI 475FtM, a new
prosthesis that has recently been specifically designed for FTM
Phalloplasty patients. It has several advantages: a large base for
pubic bone fixation, realistically shaped hard glans, and a pump
shaped like a testicle. Complications after 21 implantations
included 2 (9.5%) infections that were medically treated (Clavien
II), 1 (4.7%) infection treated by explantation (Clavien IIIb), 2
(9.5%) mechanical failures (Clavien IIIb), and 1 (4.7%)
malpositioning (Clavien IIIb). 13 of 14 patients (92.8%) who
answered a satisfaction questionnaire were satisfied or very
satisfied with the prosthesis. Preliminary results for the ZSI 475
FtM are encouraging. Safety seems to be satisfactory, and patient
satisfaction is high. Long-term studies are needed.
