A hemostasis valve for use in a medical device. The hemostasis valve may include a generally cylindrical body having a proximal side, a distal side, and a thickness extending therebetween. The proximal side may include a tapered central region having a surface sloped towards a center of the body and the distal side may include a distally extending curved central region.

An introducer sheath includes an elongate shaft having a proximal end, a distal end and a lumen extending therebetween. An actuatable hemostasis valve in a hub is adjacent the proximal end of the elongate shaft and may be used to prevent blood from escaping from the elongate shaft. The introducer sheath may also have a a self-expanding funnel adjacent the distal end of the elongate shaft.

A system for insertion into a vasculature of a patient is disclosed. The system utilizes a primary tubular sheath body coupled to a distal portion of an intermediate tubular sheath body, and a hub coupled to a proximal portion of the intermediate tubular sheath. The hub may be couplable to a dilator via an interaction between a dilator cap and the hub, and the hub may contain a hemostatic valve with a foam member having one or more visibly identifiably regions.

An antimicrobial catheter includes an elongated body adapted to be inserted into a body cavity of a patient that is not vascular or the urethra. An antimicrobial surface is positioned along an exterior circumferential surface of the elongated body, wherein the antimicrobial surface is configured to inhibit pathogens. The elongated body has at least one interior lumen defined by a sidewall forming the elongated body. The exterior circumferential surface extends between a first end of the elongated body and a second end of the elongated body.

A valve body and a medical instrument provided with the valve body can stably maintain sealing performance for preventing air/blood leakage while maintaining a smooth insertion feeling even when various types of medical devices are repeatedly inserted and removed. The valve body includes a main body portion having oppositely facing first and second surfaces, an outer peripheral surface extending between the first and second surfaces, and an insertion portion having an inner surface defining a gap that allows insertion of a medical device and formed at least on the first surface. The main body portion contains a self-repairing material that allows self-repairing damage resulting from contact with the medical device. At least part of the inner surface of the insertion portion is provided with a coating layer that prevents the gap from being closed by self-repair when portions of the inner surface of the insertion portion contact each other.

A vacuum aspiration system may be used to treat thromboembolic disease, such as deep vein thrombosis or pulmonary embolism. The system includes a housing, and a fluid flow path extending through the housing. A first catheter is in fluid communication with the flow path, and a connector is configured to place a source of aspiration in communication with the flow path. A clot container is carried by the housing. A hemostasis valve is provided in the housing, and configured to receive a second catheter and direct the second catheter through the first catheter.

A split dilator aspiration system is disclosed. The system includes a catheter, having an elongate, flexible tubular body with a proximal end, a distal end, a side wall defining a central lumen, and a handle on the proximal end. A dilator is advanceable through the central lumen, the dilator having an elongate body, cannulated to receive a guidewire, and an axially extending split along at least a portion of the elongate body, configured to allow removal of a portion of the dilator laterally from the guidewire.

Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.
