Abstract

A valve assembly includes a housing, a collar, a sheath fixedly coupled to the collar, and a stem assembly. The collar and the sheath can be axially moveable relative to the housing between a first position, a second position, and a third position. In the first position, a fluid inside a lumen of the housing can be blocked from flowing into a lumen of the collar. In the second position, the fluid inside the lumen of the housing can flow through the lumen of the collar and into a chamber of the sheath. The fluid can be retained therein or flow out of the sheath through an aperture when the sheath is selectively deformed. In the third position, the fluid inside the lumen of the housing can flow through the lumen of the collar and the chamber, and then flow out of the sheath unobstructed through the aperture.

Claims20

Dependent claims

A valve assembly, comprising:

a housing;
a collar movably coupled to the housing;
a sheath coupled to the collar;
and
a stem assembly positioned inside the housing, the collar, and the sheath;
wherein the collar is axially moveable relative to the housing between a first position, a second position, and a third position;
wherein when the collar is in the first position, the stem assembly is configured to block a fluid inside a lumen of the housing from flowing into a lumen of the collar;
wherein when the collar is in the second position, the stem assembly is configured to allow the fluid to flow from the lumen of the housing through the lumen of the collar and into a chamber of the sheath, and when the collar is in the second position the stem assembly is further configured to:
(i) retain the fluid inside the chamber of the sheath when an aperture of the sheath is blocked by the stem assembly, or
(ii) allow the fluid to flow out of the sheath through the aperture when the sheath is selectively deformed around the stem assembly;
and
wherein when the collar is in the third position, the stem assembly is configured to allow the fluid to flow from the lumen of the housing through the lumen of the collar, into the chamber of the sheath, and then out of the sheath unobstructed through the aperture.

9 more elements

A valve assembly, comprising:

a housing;
a collar movably coupled to the housing;
a sheath fixedly coupled to the collar;
and
a stem assembly fixedly coupled to the housing;
wherein the stem assembly comprises a bias member which can be compressed to a biased position by moving the collar toward the housing or return to an unbiased position by pushing the collar away from the housing;
wherein when the bias member is in the biased position, the stem assembly is configured to block a fluid inside a lumen of the housing from flowing into a lumen of the collar;
wherein when the bias member is in the unbiased position, the stem assembly is configured to allow the fluid to flow from the lumen of the housing through the lumen of the collar and into a chamber of the sheath;
wherein the collar is configured to be moveable between a first position and a second position;
wherein when the collar is in the first position, the stem assembly is configured to:
(i) retain the fluid inside the chamber of the sheath when an aperture of the sheath is blocked by the stem assembly, or
(ii) allow the fluid to flow out of the sheath through the aperture when the sheath is selectively deformed around the stem assembly;
and
wherein when the collar is in the second position, the stem assembly is configured to allow the fluid to flow out of the sheath unobstructed through the aperture.

11 more elements

A valve assembly, comprising:

a housing comprising a lumen having an orifice;
a collar movably coupled to the housing;
a sheath fixedly coupled to the collar;
and
a stem assembly fixedly coupled to the housing, a distal end portion of the stem assembly comprising a plug and a proximal end portion of the stem assembly comprising a disk;
wherein the collar is configured to be axially moveable relative to the housing between a first position, a second position, and a third position;
wherein when the collar is in the first position, the plug of the stem assembly is configured to seal the orifice of the lumen of the housing;
wherein when the collar is in the second position, the plug of the stem assembly is in an unseated position relative to the orifice of the lumen of the housing and the disk of the stem assembly is configured to seal an aperture of the sheath;
and
wherein when the collar is in the third position, the plug of the stem assembly is in the unseated position relative to the orifice of the lumen of the housing and the disk of the stem assembly is in an unsealed position relative to the aperture of the sheath.
