Claim 1
Independent Claim
209 words
A valved drainage-control device adapted to be implanted in a cavity and passage of a living body for the purpose of shutting off or allowing the flow of liquid from the cavity through said passage, comprising in combination: a. valve means adapted to be disposed in said body cavity for controlling liquid flow therefrom through said passage, said valve means including a valve housing having a valve seat and a movable valve cooperable with said seat, b. actuator means for said valve, including at least one slender, flexible wire adapted to extend through said body passage to the exterior of the body, c. means providing a collapsible enlargement, attached to said valve housing for retaining the housing in said body cavity during normal movements of the body, d. a slim elongate flexible tube at one end connected to said valve housing and collapsible enlargement means and adapted for disposition in said body passage to provide for the flow of liquid therethrough, said flexible wire extending through the flexible tube to the exterior of the body and having a fluidtight seal with said tube to prevent loss of pressure from the tube, e. the other end of said tube being disposed outside of the body and constituting a discharge orifice.

A valved drainage-control device adapted to be implanted in a cavity and passage of a living body for the purpose of shutting off or allowing the flow of liquid from the cavity through said passage, comprising in combination: a. valve means adapted to be disposed in said body cavity for controlling liquid flow therefrom through said passage, said valve means including a valve housing having a valve seat and a movable valve cooperable with said seat, b. actuator means for said valve, including at least one slender, flexible wire adapted to extend through said body passage to the exterior of the body, c. means providing a collapsible enlargement, attached to said valve housing for retaining the housing in said body cavity during normal movements of the body, d. a slim elongate flexible tube at one end connected to said valve housing and collapsible enlargement means and adapted for disposition in said body passage to provide for the flow of liquid therethrough, said flexible wire extending through the flexible tube to the exterior of the body and having a fluidtight seal with said tube to prevent loss of pressure from the tube, e. the other end of said tube being disposed outside of the body and constituting a discharge orifice.
Claim 3
Dependent Claim
39 words
A valved drainage-control device as in claim 1, wherein: a. the flexible tube has multiple perforations in its walls, to permit a flushing of the walls of the body passage when the valve is actuated to the open position.
Claim 4
Dependent Claim
24 words
A valved drainage-control device as in claim 2, wherein: a. the flexible tube comprises an inert plastic, b. said wall perforations having rounded edges.
Claim 5
Dependent Claim
30 words
A valved drainage-control device as in claim 1, wherein: a. the actuator means comprises an electromagnet connected to the valve, and a circuit therefor comprising the said slender, flexible wire.
Claim 6
Dependent Claim
64 words
A valved drainage-control device as in claim 4 and further including: a. means providing a channel extending longitudinally along said flexible tube, b. said tube and channel-providing means being constituted of inert plastic, c. said retainer means comprising an inflatable bulb surrounding said flexible tube and communicating with said channel to receive an inflating fluid therefrom, d. said slender wire extending through said channel.
Claim 7
Dependent Claim
24 words
A valved drainage-control device as in claim 4, wherein: a. the valve comprises a permanent magnet, b. said electromagnet being adapted for battery energization.
Claim 8
Dependent Claim
83 words
A valved drainage-control device as in claim 4, wherein: a. the movable valve comprises a magnetic core, and b. one end of the flexible tube being closed and containing said valve means and electromagnet, c. said movable valve comprising a flexible and resilient deflectable diaphragm spanning the interior of the flexible tube at the location of the valve means, and forming a sealed chamber at the closed end of the tube, d. said magnetic core and electromagnet being disposed in said sealed chamber.
Claim 9
Dependent Claim
32 words
