Selective Fluid Barrier Valve Device and Method of Treatment

摘要

Selective fluid barrier valve devices and methods of treatment are described herein. An embodiment of a selective fluid barrier valve device comprises a housing, an actuator, a sleeve, a wire member, and a connector. The sleeve defines a passageway that extends through the sleeve. The actuator is moveable between a first position and a second position. When the actuator is in the first position, the sleeve is in a first configuration such that fluid can pass through the passageway defined by the sleeve. When the actuator is in a second position, the sleeve is in a second configuration such that fluid is prevented from passing through the passageway defined by the sleeve.

1. A selective fluid barrier valve device having a lengthwise axis and comprising:
a housing having a housing proximal end, a housing distal end, and a housing body defining a housing passageway and a first opening, the housing passageway extending through the housing, the first opening extending through the housing body and providing access to the housing passageway; an actuator moveably attached to the housing and moveable between a first position and a second position; a sleeve disposed within the housing passageway and having a sleeve proximal end, a sleeve distal end, and a sleeve body defining a sleeve passageway extending through the sleeve, the sleeve moveable between a first configuration in which the sleeve passageway is open such that fluid can pass through the sleeve passageway and a second configuration in which the sleeve passageway is closed preventing fluid from passing through the sleeve passageway; and a first wire member having a first wire member first end attached to the housing and a first wire member second end attached to the actuator, the first wire member extending between the housing and the sleeve and through the first opening defined by the housing; wherein the sleeve is in the first configuration and the sleeve proximal end is disposed a first distance from the housing proximal end when the actuator is in the first position; wherein the sleeve is in the second configuration and the sleeve proximal end is disposed a second distance from the housing proximal end when the actuator is in the second position; and wherein the second distance is different than the first distance.
