A penile prosthesis adapted for the surgical implantation in the penis for the treatment of erectile impotence is provided, which penile prosthesis comprises an elongated gooseneck-type shell element, for example, composed of a helically wound strip material, the gooseneck-type element stiff in character to retain its position and which resists flexure, but which flexure may be overridden manually; end cap means positioned at each end of the gooseneck-type element to provide protection therefor; and sheathing means integral with the end cap means to enclose and seal the gooseneck-type rod element and end cap means, thereby providing an implantable penile prosthesis, whereby upon implantation an erect or flaccid penile posture can be obtained at will by overriding manually the resistance to flexure of the rod-like element.

Implantable penile prosthesis

A device for blowing powder onto teeth, the device consisting of a handpiece in the form of a housing connected to a compressed air source and having a discharge nozzle member which can be inserted in a patient's mouth and can be directed towards the patient's teeth. The housing has a powder reservoir with a bottom supply duct. An apertured shuttle bar is reciprocably slidably mounted beneath said duct and has a metering hole registrable with said supply duct and then, by longitudinally moving the bar, with a discharge conduit arranged to receive compressed air from the source so as to discharge a metered amount of powder in said hole into the nozzle member for delivery to the patient's teeth.

Powder blower device

A device for the delivery of a tubal-occluding polymer for sterilization of females, which device comprises a plurality of concentric tubes with a two-compartment balloon at the one end thereof.

Apparatus for and method of sterilization by the delivery of

A mechanical penile prosthesis designed to be surgically implanted in the penis for the treatment of erectile impotence or as a functional component of a penile replacement prosthesis. The penile prosthesis comprises a pre-stretched, flexible, elastic, tubular component or sheath closed at each end thereof, and a plurality of cylindrically shaped segments or links, each having one or more convex ends and/or a concave end, enclosed within the tubular component. The pre-stretched tubular sheath maintains the segments in reference to one another, i.e. link-to-link contact, so that on straightening of the normally curved tubular enclosure a concave end of a segment mates with a convex end of an adjacent segment whereby the segments are aligned into a straight rod configuration resulting in an erect penis.

A penile prosthesis adapted for surgical implantation in the penis for the treatment of erectile impotence is provided, which penile prothesis comprises a bundle of parallel flexible, plastic, rod-like elements which, due to internal surface friction between the individual rod elements, resist flexure, the rod elements tightly wrapped in a flexible sheath element, each end of the rod elements having a plastic cap means to protect the prosthesis from damage by the bundled plastic rod elements and a flexible medically acceptable material which sheaths the rod elements to seal out body fluids and tissue, whereby on implantation an erect or flaccid penile posture can be obtained at will.

A two-stage, sterilizable connector for use in processing blood, which connector assures sterility when entering a blood bag to add agents required in processing blood, the connector designed to comprise a male and female body element which, in a first extended position, are partially joined, which connector is sterilizable, and which, after sterilization, the male and female body elements are joined in a secured, engaged position to effect the puncturing of the male and female septa to provide a fluid passageway therethrough.
