Patent Issued for Implantable Medical Device Having a Palpatable Activation Surface

June 20, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventor Chechik, Joel Craig (Minneapolis, MN), filed on May 24, 2013, was published online on June 3, 2014 (see also Coloplast A/S).

The assignee for this patent, patent number 8740769, is Coloplast A/S (Humlebaek, DK).

Reporters obtained the following quote from the background information supplied by the inventors: "An implanted penile prosthetic is effective in relieving erectile dysfunction in men.

"A penile prosthetic typically includes one or more cylinders that are implanted in the corpora cavernosa of the penis, a reservoir implanted in the abdomen that communicates with the cylinder(s), and a pump located in the scrotum that is employed to move liquid from the reservoir into the cylinder(s).

"In a typical application, the user squeezes a bulb of the pump multiple times to draw liquid out of the reservoir, into the bulb, and move the liquid into the cylinders. The repeated squeezing of the bulb moves the liquid from the reservoir into the cylinders, which incrementally deflates the reservoir and incrementally inflates the cylinder(s) to eventually provide the user with an erect penis. The user may return the penis to its flaccid state by activating a release mechanism associated with the pump to selectively transfer the liquid from the cylinder(s) back into the reservoir.

"The above-described penile prosthetics have proven effective in relieving erectile dysfunction in men. However, there is a desire for improved penile prosthetic devices."

In addition to obtaining background information on this patent, NewsRx editors also obtained the inventor's summary information for this patent: "One aspect provides a penile prosthetic that includes a cylinder, a reservoir, a pump, and a deflation assembly. The cylinder is implantable in a corpora cavernosum. The pump is attachable between the cylinder and the reservoir and is operable to move fluid from the reservoir to inflate the cylinder. The deflation assembly is attachable between the pump and the reservoir and includes a valve that selectively restricts movement of the fluid from the cylinder to the reservoir, a base and an activation surface opposite the base, where the activation surface includes an outer peripheral rim surrounding a pad that is movable to displace the valve to allow the fluid to flow from the cylinder to the reservoir. An entirety of the pad is recessed relative to the outer peripheral rim such that the outer peripheral rim defines a maxima of the activation surface.

"One aspect provides a method of implanting a medical device that includes implanting an inflatable penile prosthetic into a penis of a patient, coupling the penile prosthetic to a reservoir, a pump, and a deflation assembly, where the deflation assembly is separate from the reservoir and separate from the pump. The method additionally includes implanting the deflation assembly between transversalis fascia and an exterior surface of a pelvis of the patient. The deflation assembly includes a palpatable activation surface."
