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.

An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.

Aspects herein relate to a low-friction septum for providing a leak-resistant seal for use in a vascular access device. In an embodiment, a device for vascular access hemostasis is included having an enclosure defining a cavity and configured to at least partially receive a medical device. The device can include a first seal portion and a second seal portion, the cavity disposed between the first seal portion and the second seal portion. The device can include a barrel in structural communication with the second seal portion, the second seal portion including a septum seal. The second seal portion can define two or more discrete portions, each separated by one or more split lines. The discrete portions can include a mating surface to interface with mating surfaces of other discrete portions. The mating surface can include a surface topology including raised portions and depressions. Other embodiments are also included herein.

A subcutaneous drain includes cap portion and a base with a central opening including a valve element that opens and closes to allow for withdrawal and addition of fluid into the patient's body. In embodiments, the drain may include a seal assembly to prevent leakage around a drain catheter that passes through the drain.

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 system for facilitating instrument delivery through a peripheral intravenous catheter (“PIVC”) may include a catheter assembly having a catheter adapter, an extension tube extending from a side port of the catheter adapter, a septum disposed in a lumen of the catheter adapter, and a PIVC extending distally from the catheter adapter. The septum may include a first piece and a second piece and may be least partially disposed within a canister. The system may include an extension set, which may include a distal end and a proximal end. The distal end may include a distal connector and a rigid tube. The proximal end may include a proximal connector. The distal connector may be coupled to the proximal end of the catheter adapter. The rigid tube may penetrate the septum in response to the distal connector being coupled to the proximal end of the catheter adapter.

A valved trocar cannula for insertion into an eye includes a trocar cannula having a distal end configured to be positioned within the eye and a proximal end configured to be positioned outside the eye. An elastomeric membrane or seal is attached to the trocar cannula at the proximal end thereof and restricts a free flow of fluid from within the trocar cannula to outside the proximal end of the trocar cannula. The elastomeric membrane includes at least one slit extending therethrough and is arranged to permit the passage of a surgical instrument through the membrane and into the trocar cannula. The slit may through the elastomeric membrane at an oblique angle along a least a portion of the slit. Pressure applied across a first surface or a second surface of the elastomeric membrane in a vicinity of the slit tends to keep the slit in a closed position.

A medical device includes: a first member including: a body portion, and an anchor, wherein a resin material of the anchor is different from a resin material of the body portion, and wherein the anchor is interlinked to the body portion; and a second member including a connecting portion that is connected to the anchor, wherein a resin material of the second member is the same as the resin material of the anchor.
