Patent ID: 8034045

Claim:
A sheath for use with a medical device, comprising: an inner liner defining a lumen extending longitudinally through the sheath; a coil having a series of windings with an outer surface and inner surface, the coil having a predetermined coil spacing between adjacent coil windings to define voids between adjacent windings, the coil fitted around at least a part of the inner liner; an intermediate layer disposed between the inner surface of the coil windings and a portion of the inner liner and adapted to bond to the inner surface of the coil and to the inner liner; and an outer layer positioned over and attached to the outer surface of the coil, the outer layer having a lower melt temperature than the inner liner, wherein the inner liner and the outer layer are adhered to the coil independent from one another so that in response to the bending of said sheath the inner liner and the outer layer are capable of moving coaxially independent relative to one another.
