Reloadable sheath for catheter system for deploying vasoocclusive devices

A sheath for a therapeutic vasoocclusive device, the vasoocclusive device including an assembly of a flexible pusher member and an embolic coil, the sheath comprising:

• a hollow, elongated tubular member having opposing upper and lower walls, opposing side walls, and a longitudinal interior channel;
• a longitudinal slot formed in the upper wall of the elongated tubular member and extending the length of elongated tubular member, the slot having opposing sides with inner side surfaces extending through the upper wall of the elongated tubular member leading to the interior channel permitting introduction of the vasoocclusive device into the interior channel, wherein the upper wall of the elongated tubular member adjacent to the slot has an angled configuration on the outside surface of the hollow, elongated tubular member.

A sheath in combination with a vasoocclusive device, the vasoocclusive device including an assembly of a flexible pusher member and an embolic coil that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, the sheath comprising:

• a hollow, elongated tubular member having opposing upper and lower walls, opposing side walls, and a longitudinal interior channel, and
• a longitudinal slot formed in the upper wall of the elongated tubular member and extending most of the length of elongated tubular member, leaving up to about 10 cm with no slot, the slot having opposing sides with inner side surfaces extending through the upper wall of the elongated tubular member leading to the interior channel permitting introduction of the vasoocclusive device into the interior channel.
