A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

An access sheath and method of assembling the access sheath. The access sheath includes a hub, a cartridge carried by the hub, the cartridge having a first valve, a second valve spaced from the first valve along a central axis, and a spacer disposed between the first valve and the second valve, wherein the first valve and the second valve each have at least two slits that extend along, and twist about, the central axis, and a shaft assembly having a shaft hub and a shaft that extends from the shaft hub in the distal direction. The access sheath provides a liquid-tight seal when receiving the introducer and other devices to prevent leakage and blood loss and to decrease device insertion forces.

Valve systems and steering systems for catheters and methods of using the same.

A medical connector for use in a fluid pathway includes a substantially transparent housing having a proximal end with a proximal opening and a distal end with a distal opening, and a cavity extending therebetween. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.

A seal for a hemostasis valve is provided as well as a novel seal stack for use in hemostasis valves. The seal stack includes a plurality of conical or frustoconical members including an anti-prolapse member, and a sealing member. The seal stack may optionally include a diaphragm and/or a second sealing member. The valve body may include a pressure sensing member which may be located in a sidearm.

A hemostasis valve hub for a sheath, such as an introducer sheath, includes a hub base including a first arm defining a first lumen and having a distal end and a proximal end and a second arm extending from the first arm and defining a second lumen and having a distal end and a proximal end, a seal positioned within the first lumen and adjacent a lock nut, the lock nut engaged with the proximal end of the first arm and positioned at least partially within the first lumen, a primary seal positioned adjacent the proximal end of the first arm, and a secondary seal positioned adjacent the proximal end of the second arm.

A hemostasis valve hub for use with an introducer sheath includes a base having a securing mechanism for securing the hemostasis valve hub to the introducer sheath, an outer shell securable to the base and defining an interior volume, a shutter helix section disposed within the interior volume and including a plurality of fins arranged in a helical fashion, a brush section disposed within the interior volume adjacent the disk shutter section, the brush section including a plurality of brushes arranged in a helical fashion, and a seal positioned within the base and adjacent the brush section, the seal having a partial cross slit arrangement.

This patent document discloses devices and associated methods for catheter and guidewire management in a surgical setting. Implementations can include a hemostasis valve configured to prevent the backflow of blood during a medical procedure. The hemostasis valve can have a valve body defining an inner lumen extending from a proximal end of the body to a distal end of the body. The inner lumen can be configured to accommodate passage of one or more elongate interventional devices therethrough. An interventional device management component can be positioned at the proximal end of the valve body. The interventional device management component can comprise a body defining a first seal member lumen configured to receive a first elongate interventional device and a second seal member lumen configured to receive a second elongate interventional device. A narrow slit configured to receive a guidewire can connect the seal member lumens.

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending therethrough. The catheter assembly may also include a septum slidably disposed within the lumen. The septum may include a distal end, a proximal end, and a barrier disposed between the distal end of the septum and the proximal end of the septum. The barrier may divide an interior of the septum into a distal cavity and a proximal cavity. A distal face of the barrier may include a protrusion. The barrier may include a slit extending through the protrusion for selectively opening fluid communication between the distal cavity and the proximal cavity.

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.
