DURASPHERE injectable bulking agent is a permanent solution to treat ISD type of female stress urinary incontinence.
Manufacturer: Carbon Medical Technologies
Durasphere is composed of pyrolytic carbon coated graphite beads suspended in a water-based carrier gel (2.8% Glucan). Pyrolytic carbon-coated graphite beads will not be degraded by the body, so the bulking effect is maintained, and the procedure does not need to be repeated annually, like other bulking agents.
DURASPHERE is effective and well tolerated with an excellent safety profile. Over 100,000 procedures have taken place worldwide. DURASPHERE offers surgeons a long term, less invasive support for the urethra:
NICE Guidelines in Urinary Incontinence suggest considering intramural bulking agents, including those of carbon coated zirconium beads, for the management of SUI (if conservative management has failed.)
Durasphere® is injected sub-mucosally at the bladder neck. The injection of Durasphere® creates increased tissue bulk and subsequent coaption of the bladder neck and/or the urethra.
Durasphere® is designed to flow more easily down the delivery needle to reduce delivery obstruction
Long Term Durability
73% of patients who participated in the U.S. IDE study reported that they maintained their 1-year post procedure continence grade at 4.3 years post procedure.
Pyrolytic carbon coating has been used for 30 years in the heart valve industry.
No skin test is necessary. No refrigeration of the product is required.
Durasphere® must not be used in patients with acute cystitis, urethritis, or other acute genitourinary infections.
