Abstract
Abstract An implant method according to which an implant which comes in contact with a body fluid is placed in communication with a reservoir having a relatively large supply of an agent for influencing a component of the body fluid. The device has a tubular portion which receives the body fluid and which communicates with a reservoir which contains the agent for influencing the component of the body fluid.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
110 words
In a method for controlling body fluid in a body cavity of a living being, the steps of situating in the body cavity of the living being an implant which receives the body fluid which is to be controlled and which has in its interior an agent which is contacted by the body fluid and which influences at least a component of the body fluid, and placing in communication with the implant a reservoir containing a relatively large supply of said agent for replenishing the latter, so that the influence of the agent on the component of the body fluid can be maintained effective over a long period of time.
Claim 2
Dependent Claim
110 words
In a method for controlling body fluid in a body cavity of a living being, the steps of situating in the body cavity of the living being an implant which receives the body fluid which is to be controlled and which has in its interior an agent which is contacted by the body fluid and which influences at least a component of the body fluid, and placing in communication with the implant a reservoir containing a relatively large supply of said agent for replenishing the latter, so that the influence of the agent on the component of the body fluid can be maintained effective over a long period of time.
Claim 3
Dependent Claim
15 words
In a method as recited in claim 1 and wherein the agent is a solid.
Claim 4
Dependent Claim
15 words
In a method as recited in claim 2 and wherein the agent is a metal.
Claim 5
Dependent Claim
15 words
In a method as recited in claim 1 and wherein the agent is a non-solid.
Claim 6
Dependent Claim
15 words
In a method as recited in claim 4 and wherein the agent is a liquid.
Claim 7
Dependent Claim
24 words
In a method as recited in claim 1 and wherein the body cavity is a vas deferens and the agent is a spermicidal agent.
Claim 8
Dependent Claim
29 words
In a method as recited in claim 1 and including the step of adjusting the extent to which the component of the body fluid is exposed to the agent.
Claim 9
Dependent Claim
29 words
In a method for controlling semen in a male being having a pair of vas deferentia, the step of connecting an implant with only one of the vas deferentia.
Claim 10
Dependent Claim
29 words
In a method for controlling semen in a male being having a pair of vas deferentia, the step of connecting an implant with only one of the vas deferentia.
Claim 11
Dependent Claim
15 words
In a method as recited in claim 8 and wherein the implant is a valve.
Claim 12
Dependent Claim
68 words
An implant comprising tubular means having a hollow interior for receiving a body fluid, an agent in said hollow interior of said tubular means for influencing at least a component of the body fluid, and reservoir means operatively connected with said tubular means and communicating with the hollow interior thereof, said reservoir means containing said agent for replenishing the latter in the hollow interior of said tubular means.
Claim 13
Dependent Claim
68 words
An implant comprising tubular means having a hollow interior for receiving a body fluid, an agent in said hollow interior of said tubular means for influencing at least a component of the body fluid, and reservoir means operatively connected with said tubular means and communicating with the hollow interior thereof, said reservoir means containing said agent for replenishing the latter in the hollow interior of said tubular means.
Claim 14
Dependent Claim
40 words
The combination of claim 10 and wherein said reservoir means forms an extension of the hollow interior of said tubular means and said agent is in the form of a solid body situated in said extension and said tubular means.
Claim 15
Dependent Claim
44 words
The combination of claim 10 and wherein said agent is a liquid, said reservoir means including a container whic contains said liquid and a wick extending from the interior of said container to the interior of said tubular means and extending into the liquid.
Claim 16
Dependent Claim
92 words
The combination of claim 10 and wherein a valve means includes a housing having an inlet and an outlet and also includes a movable valve member situated between said inlet and outlet and formed with a passage which forms said tubular means, said valve member having at least one position where said passage communicates with said inlet and outlet so that in the latter position of said valve member the agent in said reservoir means is effective to influence the component of a body fluid which is received in the valve means.
Claim 17
Dependent Claim
44 words
The combination of claim 13 and wherein said valve member is formed with a second Passage which does not communicate with said reservoir means and which can selectively be placed in communication with the inlet and outlet to eliminate the influence of the agent.
Claim 18
Dependent Claim
74 words
The combination of claim 14 and wherein both of said passages have configurations for mutually exclusive or simultaneous communication with said inlet and outlet, and said valve member being adjustable for providing only communication with one or the other of the passages or for providing a selected extent of communication of the inlet and outlet with both of said passages for controlling the influence of the agent on the component of the body fluid.
Claim 19
Dependent Claim
26 words
The combination of claim 15 and wherein the valve housing is adapted to be received in a vas deferens and the agent is a spermicidal agent.
