A medical device including a sheath (20) having an inner liner (50) and an outer layer (40) attachable to a coil (34) independent from each other to allow the inner liner and the outer layer the freedom to move coaxially independent from each other. The coil can be closely wound at a predetermined coil spacing sufficient to inhibit portions of the outer layer from entering into voids between the adjacent coil windings. Intermediate layers (52) for bonding between the coil and the inner liner and/or the outer layer may also be provided. A filler material (60) can be disposed within the voids between the adjacent windings of the coil. The filler material has a dimension sized to bridge the void between adjacent coil windings in order to inhibit portions of the outer layer from bonding to the inner liner. The filler material can be in the form of a ribbon (62). |
