A hemostasis valve for use with catheters in intravascular procedures. The hemostasis valve comprising a sealable fluid channel that bifurcates from a single distal lumen to two proximal lumens. An upper proximal lumen may include a funnel shaped opening to improve aspiration potential. Rotating locking mechanisms are attachable at the ends of the hemostasis valve to interlock coaxial devices or to form seals around coaxial devices. Injection molding may be used to manufacture a hemostasis valve and its components. A mold and core pins may impart external and internal shapes to a molten polymer. Once the polymer has cooled, the molded component is separated from any pins or molds and attached to other molded components to form an assembled hemostasis valve.

A bleed-back control valve is provided having a sidearm and an integrated three-way stopcock switching between two alternative fluid paths. One of the alternative fluid paths communicates with an inline pressure transducer embedded in the wall of the sidearm. The bleed-back control valve also includes a purge valve located near the blunted apex of a conical seal located in the main valve body. The purge may be opened to expel air from the space around the blunted apex.

A system for providing vascular access in a patient's body may comprise at least one hemostatic valve and at least one clamp to be used with a vascular graft. The vascular graft comprises a tubular body having a proximal end and a distal end, the proximal end being configured to be attached to a vessel in a patient's body. The at least one valve is configured to be attached to the distal end of the graft's tubular body and comprises a housing including a flexible membrane that allows a medical device to be inserted through the membrane into said vascular graft. The valve further comprises an introducer sheath configured to be inserted into the distal end of the graft's tubular body. The at least one clamp is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath into the distal end of the graft's tubular body and a second configuration that allows clamping of the graft against the valve's introducer sheath, when inserted in the graft's tubular body.

A method for replacing a stenotic native aortic valve of a patient can include inserting a delivery apparatus into a femoral artery of the patient, the delivery apparatus having a first shaft extending from the handle, a second shaft disposed around the first shaft, a third shaft extending through the second shaft, and a valve cover coupled to the first shaft. The valve cover can be in a first state housing an entirety of a prosthetic heart valve and retaining the prosthetic heart valve in a radially compressed state during the act of inserting. The method can further include advancing the delivery apparatus through the aorta of the patient to position the valve cover and the prosthetic heart valve within the native aortic valve, and moving the valve cover longitudinally from the first state to a second state in which the entirety of the prosthetic heart valve is uncovered.

Hemostasis valves and hemostasis valve systems are provided. A hemostasis valve can include a valve member, wherein the valve member includes a first sealable opening disposed through a first portion of the valve member and a second sealable opening disposed through a second portion of the valve member. The valve member may also include three or more sealable openings. A hemostasis valve system may include a hemostasis valve and another medical device. The hemostasis valve may be releasably coupleable to the other medical device.

A cannula for use in an access assembly includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.

A signal measured by a sensor connected to a needleless connector including a fluid flow path may be obtained to determine, based on the signal, an event associated with the needleless connector, such as at least one of: a scrubbing event in which the needleless connector is scrubbed with a disinfectant, a flushing event in which the needleless connector is flushed with a solution, a connection event in which the needleless connector is connected to a medical device, a disconnection event in which the needleless connector is disconnected from the medical device, or any combination thereof. An indication of the determined event may be provided.

A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body. The at least one clamp (210) is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath (615) into the distal end (110B) of the graft's tubular body and a second configuration that allows clamping of the graft (110) against the valve's introducer sheath (615), when inserted in the graft's tubular body.

Collapsible tube embodiments may be used to promote hemostasis at surgical sites or any other suitable location. In some cases, vascular closure device embodiments may include collapsible tube embodiments in order to promote hemostasis at a surgical site during a vascular closure procedure.

A hemostasis valve device includes a valve body having an open first end and an open second end with a main lumen extending from the open first end to the open second end. The valve includes a valve member disposed within the main lumen of the valve body at or proximate to the open first end, the valve member having an open position and a closed position. An actuator is disposed between the valve member and the open second end. The actuator is configured to move the valve member between the open position and the closed position.
