The introducer sheath can be loaded onto a vasoocclusive device after removal of the vasoocclusive device from a microcatheter, to permit the vasoocclusive embolic coil assembly to be used again during a clinical procedure. The sheath includes a hollow, elongated tubular member with a longitudinal slot formed in the upper wall of the elongated tubular member and extending along the length of elongated tubular member. The upper wall of the elongated tubular member adjacent to the slot has an angled configuration to accept the vasoocclusive device. The sheath may include wing members extending outwardly from the angled configuration on the outside surface of the hollow, elongated tubular member to facilitate insertion of the vasoocclusive device into the sheath. The elongated tubular member may also consist of a segment with no slot attached to a flexible pusher member to facilitate initiation of loading of the vasoocclusive device into the sheath.

Reloadable sheath for catheter system for deploying vasoocclusive devices

The present invention provides low profile intravascular ultrasound catheters adapted to access sites within the patient's body through narrow blood vessels, e.g., the radial artery. In an embodiment, a low profile catheter comprises an catheter sheath, a short guidewire receiver attached to the distal end of the catheter sheath, and a telescope assembly at the proximal end. The catheter sheath comprises a main portion and a tapered portion for increased flexibility toward the distal end of the catheter. In one embodiment, a rotatable and translatable imaging core is received within the catheter sheath for ultrasound imaging. A short guidewire receiver is used to allow the imaging core to be advanced farther distally with respect to the distal end of the catheter. In an embodiment, the catheter sheath extends through a portion of the telescope assembly to provide enhanced support of the imaging core within the telescope assembly.
