摘要： Hemostasis valves and hemostasis valve assemblies can be coupled to a proximal end of an introducer sheath to prevent blood loss through the proximal end of the introducer sheath. Some hemostasis valve assemblies may include an elastomeric member with a variable-width channel that is designed to form a liquid-tight seal over elongate members of different diameter or a single elongate member of variable diameter.

摘要： A sheath assembly for the insertion of a percutaneous pump includes a tubular sheath body dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall having a proximal end portion, a distal end portion, a longitudinal axis, an outer surface, an inner surface defining a first lumen substantially parallel to the longitudinal axis, and a second lumen disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

摘要： A sheath assembly (100) for the insertion of a percutaneous pump includes a tubular sheath body (102) dimensioned for insertion into a blood vessel through a vessel aperture. The tubular sheath body includes a wall (104) having a proximal end portion (106), a distal end portion (108), a longitudinal axis, an outer surface, an inner surface defining a first lumen (116) substantially parallel to the longitudinal axis, and a second lumen (118) disposed within the wall between the inner surface and the outer surface and extending from the proximal end portion to the distal end portion. The first lumen is dimensioned to allow passage of a portion of the percutaneous pump, and the second lumen is dimensioned for passage of a guidewire. A stylet (120) is removably positioned to substantially occlude the second lumen. The stylet has a proximal end releasably secured to the sheath assembly.

摘要： An introducer assembly includes an elongate sheath sized for insertion into a blood vessel of a patient and a hub. The hub can be coupled to a proximal portion of the sheath and can include a first hub portion and a second hub portion. The hub can include various features to facilitate breaking apart or separating the introducer assembly from a patient. For example, the first hub portion can have a first notch which can facilitate breaking, splitting, or fracturing the hub. The second hub portion can partially surround the first hub portion and can include two wings and an opening disposed above the first notch. The first hub portion can be formed from a first material and second hub portion can be formed from a second material. In some embodiments, the second material can be stiffer than the first material to facilitate fracturing the hub.
