Abstract

Abstract An implant for a living being. A tubular organ such as a vas deferens is divided into a pair of separate portions having free ends adjacent each other. The implant has a pair of parts which are separately introduced into the lumens of the separate portions of the tubular organ while the parts of the implant remain accessible at the free ends of these separate portions of the tubular organ. These parts which are thus accessible are then joined together to render the implant operative without excessive stretching of the tubular organ so that excessive slack is not produced therein. The tubular organ may be a vas deferens while the implant is a vas valve capable of reversively blocking flow in the vas deferens and having the separate parts one of which is constituted by a tubular component and the other of which is constituted by the remainder of the vas valve, these parts being united after being introduced into the lumens to provide the assembled vas valve.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 250 words
An implant to be introduced into a tubular organ of a living being after the tubular organ has been divided into a pair of separate portions having free ends situated adjacent each other, said implant comprising a pair of parts one of which is to be introduced into the lumen of one of the separate portions and the other of which is to be introduced into the lumen of the other of the separate portions of the tubular organ, said parts remaining accessible at free ends of said separate portions of the tubular organ, and means operatively connected with said parts of the implant for connecting them to each other at the region of the free ends of the separate portions of the tubular organ for operatively connecting said parts of said implant to each other and render the implant operative after the parts thereof have been separately implanted, the tubular organ being a vas deferens and the implant being a vas valve, and said parts being respectively constituted by a tubular component which forms one of the parts and the remainder of the vas valve, said means for connecting said parts to each other including male and female tapered mating portions of said parts which fit together with a tight wedge fit, said one part of said vas valve being an elongated tubular component having a female portion of said means and terminating at said female portion of said means in an outwardly directed flange which forms a barrier.
Claim 2
Dependent Claim 250 words
An implant to be introduced into a tubular organ of a living being after the tubular organ has been divided into a pair of separate portions having free ends situated adjacent each other, said implant comprising a pair of parts one of which is to be introduced into the lumen of one of the separate portions and the other of which is to be introduced into the lumen of the other of the separate portions of the tubular organ, said parts remaining accessible at free ends of said separate portions of the tubular organ, and means operatively connected with said parts of the implant for connecting them to each other at the region of the free ends of the separate portions of the tubular organ for operatively connecting said parts of said implant to each other and render the implant operative after the parts thereof have been separately implanted, the tubular organ being a vas deferens and the implant being a vas valve, and said parts being respectively constituted by a tubular component which forms one of the parts and the remainder of the vas valve, said means for connecting said parts to each other including male and female tapered mating portions of said parts which fit together with a tight wedge fit, said one part of said vas valve being an elongated tubular component having a female portion of said means and terminating at said female portion of said means in an outwardly directed flange which forms a barrier.
Claim 3
Dependent Claim 15 words
The combination of claim 1 and wherein said barrier is formed with openings passing therethrough.
Claim 4
Dependent Claim 298 words
An implant to be introduced into a tubular organ of a living being after the tubular organ has been divided into a pair of separate portions having free ends situated adjacent each other, said implant comprising a pair of parts one of which is to be introduced into the lumen of one of the separate portions and the other of which is to be introduced into the lumen of the other of the separate portions of the tubular organ, said parts remaining accessible at free ends of said separate portions of the tubular organ, and means operatively connected with said parts of the implant for connecting them to each other at the region of the free ends of the separate portions of the tubular organ for operatively connecting said parts of said implant to each other and render the implant operative after the parts thereof have been separately implanted, the tubular organ being a vas deferens and the implant being a vas valve, and said parts being respectively constituted by a tubular component which forms one of the parts and the remainder of the vas valve, said means for connecting said parts to each other including male and female tapered mating portions of said parts which fit together with a tight wedge fit, said parts being respectively formed with bores extending along the entire length of said parts, and a pair of mandrels to be situated in said bores filling the latter during introduction of said parts into lumens oF the separate portions of the vas deferens, to prevent blocking of said bores during introduction of the parts into the lumens, respectively, so that after the parts are thus introduced into the lumens said mandrels may be removed to provide unobstructed bores in said parts of said valve.
Claim 5
Dependent Claim 298 words
An implant to be introduced into a tubular organ of a living being after the tubular organ has been divided into a pair of separate portions having free ends situated adjacent each other, said implant comprising a pair of parts one of which is to be introduced into the lumen of one of the separate portions and the other of which is to be introduced into the lumen of the other of the separate portions of the tubular organ, said parts remaining accessible at free ends of said separate portions of the tubular organ, and means operatively connected with said parts of the implant for connecting them to each other at the region of the free ends of the separate portions of the tubular organ for operatively connecting said parts of said implant to each other and render the implant operative after the parts thereof have been separately implanted, the tubular organ being a vas deferens and the implant being a vas valve, and said parts being respectively constituted by a tubular component which forms one of the parts and the remainder of the vas valve, said means for connecting said parts to each other including male and female tapered mating portions of said parts which fit together with a tight wedge fit, said parts being respectively formed with bores extending along the entire length of said parts, and a pair of mandrels to be situated in said bores filling the latter during introduction of said parts into lumens oF the separate portions of the vas deferens, to prevent blocking of said bores during introduction of the parts into the lumens, respectively, so that after the parts are thus introduced into the lumens said mandrels may be removed to provide unobstructed bores in said parts of said valve.
