A system for occluding a blood vessel includes an embolization coil having barbed fibers coupled thereto. The coil can be delivered in a straight configuration and then transition into a larger coiled structure. The barbed fibers can overlap within a lumen defined by the larger coiled structure and attached to each other to define a mesh. The barbs of the barbed fiber can limit the fibers from being pulled out of the coil, as well as provide anchoring of the coil to the blood vessel in which the coil is deployed. The barbed fibers can also be used to anchor two coils to each other.

A sheath for deploying a medical device to a target site in the body of a patient. A tubular inner liner has a proximal portion, a distal portion, and an outer surface. An outer jacket has a proximal portion, a distal portion, and an inner surface. A reinforcing member is received within a length of the outer jacket. The outer jacket is positioned longitudinally around the inner liner and bonded to the outer surface of the liner. The reinforcing member, which may be a triaxial braid, or an encapsulated longitudinal reinforcing wire, extends along the outer jacket length and is configured for inhibiting elongation of the sheath upon deployment of the device.
