摘要： A condom retainer ring structure (20) is for use on a condom (10) that has an elongated thin walled tubular sheath of resilient material closed at one end and opened at the other end, with a bead surrounding the opening. The condom retainer ring structure has a first ring (22) for positioning at the periphery of the opening, adjacent the bead that surrounds the sheath. A second ring (24) is connected to and adjacent the first ring. A bridge (26) having a retention notch (28) therein joins the rings generally in a single unflexed condition. In use, when a condom (10) is worn on the penis of a user, the first ring (22) surrounds the sheath on the shaft of the penis, the second ring (24) encircles the scrotum to anchor the condom, and the bridge (26) is flexed thereby, constricting the retention notch (28). The retention notch (28), preferably positioned over the bead of the condom, grabs the bead to retain the condom.

摘要： A catheter for balloon angioplasty includes a flexible shaft (12) defining a hollow passage (18), the shaft having first (14) and second (16) ends. A core means (20) is movably and removably mounted within the hollow passage, the core means having first and second ends adjacent the first and second ends of the shaft. The core means has a first flexible portion (26) adjacent the first end and a second flexible portion (28) of greater flexibility adjacent the second end. The core means may also have an enlarged terminal knob (30) at the second end. A flexible guide wire (32) may be fixed to the second end of either the shaft or the core means. The catheter may be inserted into a vascular tree. After removal of the core means, the core means may be replaced by an exchange wire, an angioscope, a laser fiber, or a rotatable wire. Also, when the core means is replaced by an exchange wire, the shaft may then be removed and replaced by either a different balloon angioplasty catheter or a perfusion catheter.

摘要： Un cathéter pour angioplastie à ballon comprend un arbre flexible (12) définissant un passage creux (18), l'arbre présentant une première (14) extrémité et une deuxième (16) extrémité. Une tige centrale (20) est montée de manière mobile et amovible à l'intérieur du passage creux; les première et deuxième extrémités de la tige sont adjacentes aux première et deuxième extrémités de l'arbre. La tige centrale possède une première partie flexible (26) adjacente à la première extrémité et une deuxième partie (28) présentant une plus grande flexibilité, adjacente à la deuxième extrémité. La deuxième extrémité de la tige centrale peut également être pourvue d'un bout arrondi (30). Un câble flexible de guidage (32) peut se fixer sur la deuxième extrémité de l'arbre ou de la tige centrale. Le cathéter peut être introduit dans une arborescence vasculaire. Après son extraction, la tige centrale peut être remplacée par un câble d'échange, un angioscope, une fibre pour rayon laser, ou un câble rotatif. De même, lorsque la tige centrale est remplacée par un câble d'échange, l'arbre peut être extrait et remplacé soit par un autre cathéter pour angioplastie à ballon soit par un cathéter de perfusion.
