Abstract: 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.

Abstract: 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.

Abstract: An introducer sheath for percutaneous insertion of a heart pump includes a tubular sheath body having a wall, a proximal end portion, a distal end portion, and an inner lumen. The introducer sheath includes a hemostatic valve disposed in the proximal end portion and forming a liquid tight seal across the inner lumen of the tubular sheath body. The hemostatic valve includes a valve cavity having a distal end and a proximal end, a first annular restriction formed within the valve cavity and having a first diameter, and a second annular restriction formed within the valve cavity distal to the first annular restriction and having a second diameter. The distal end of the valve cavity is spaced from the second annular restriction by a gap distance and a third diameter of the valve cavity along the gap distance is about equal to or greater than the first and second diameters.
