Abstract
A valve for blocking the flow of gas or fluid with or without an instrument in place within the gas/fluid path. The valve includes a seal module having a proximal end and a distal end with a lumen sized to allow the passage of fluids or gases.
Claims31
A valve comprising:
- a seal module having a lumen sized to allow the passage of fluids or gases, the seal module having a proximal end and a distal end;
- a resilient member disposed against an actuator;
- and
- the actuator disposed against a portion of the seal module, the actuator movable from a first position to a second position, in the first position the actuator is disposed against the portion of the seal module collapsing the lumen between the proximal end and the distal end of the seal module creating a seal, in the second position the actuator is disposed away from the portion of the seal module by a force allowing the lumen to return to an unsealed configuration.
1 more element
A valve comprising:
- a seal module having a plurality of seal members including a first seal member, a second seal member, and a third seal member extending between the first and the second seal members, the plurality of seal members each having a lumen sized to allow the passage of fluids or gases;
- and
- the first seal member having a first material, the second seal member having a second material, and the third seal member having a third material, wherein at least one of the first material of the first seal member and the second material of the second seal member is different than the third material of the third seal member.
A valve comprising:
- a seal module having a lumen sized to allow the passage of fluids or gases, the seal module having a proximal end and a distal end;
- one or more resilient members disposed against one or more actuators;
- and
- the one or more actuators disposed against a portion of the seal module, the one or more actuators movable from a first position to a second position, in the first position the one or more actuators are at least partially circumferencially disposed about the portion of the seal module collapsing the lumen between the proximal end and the distal end of the seal module creating a seal, in the second position the one or more actuators are circumferencially disposed away from the portion of the seal module allowing the lumen to return to an unsealed configuration.
1 more element
A method comprising:
- providing a seal module having a plurality of seal members including a first seal member with a first lumen in a sliding relationship with a proximal end of the seal module;
- disposing a second seal member with a second lumen against a distal end of the seal module;
- disposing a third deformable seal member with a third lumen between the first and the second seal members, the plurality of seal members sized to allow the passage of fluids or gases;
- urging the first seal member toward the second seal member where the deformable third seal member is compressed;
- and
- collapsing the third seal member creating a seal of at least a portion of the third lumen of the third seal member.
3 more elements
A method comprising:
- forming a seal module having a lumen sized to allow the passage of fluids or gases;
- disposing an actuator against a portion of the seal module with a resilient material, the actuator movable from a first position to a second position;
- collapsing the lumen between a proximal end and a distal end of the seal module creating a seal;
- and
- moving the actuator away from the portion of the seal module in the second position allowing the lumen to return to an unsealed configuration.
