Longitudinally reinforced sheath
First Claim
1. A sheath for deploying a medical device to a target site in the body of a patient, comprising:
- a tubular liner having a proximal portion, a distal portion, and an outer surface;
an outer jacket having a proximal portion, a distal portion, and an inner surface, said outer jacket positioned longitudinally around the liner such that the outer jacket inner surface is bonded to the outer surface of the liner; and
a reinforcing member received within a length of the outer jacket, said reinforcing member extending along said outer jacket length and configured for inhibiting elongation of the sheath upon deployment of said device therefrom,wherein said reinforcing member comprises a triaxial braid encapsulated along said length of the outer jacket, andfurther wherein the triaxial braid comprises strands woven in two directions in a generally biaxial pattern, and one or more strands running in a longitudinal direction relative to the strands woven in the generally biaxial pattern and interwoven between the strands woven in the generally biaxial pattern,wherein the one or more strands running in the longitudinal direction are fixed to the outer jacket and/or the tubular liner and extend proximally from the proximal portion of the outer jacket, andwherein the sheath has an outwardly flared proximal end and the one or more strands running in the longitudinal direction extend proximally beyond the outwardly flared proximal end.

Abstract
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.

8. A longitudinally reinforced sheath comprising:
-
a tubular inner liner having a proximal portion, a distal portion, and an outer surface; a reinforcing element disposed along said outer surface of said inner liner, said reinforcing element comprising a triaxial braid, said triaxial braid disposed at said proximal portion of said inner liner and extending distally therefrom, wherein the triaxial braid comprises strands woven in two directions in a generally biaxial pattern, and one or more longitudinal strands interwoven with the strands woven in the generally biaxial pattern wherein the reinforcing element extends proximally from the proximal portion of the tubular inner liner; and an outer jacket positioned longitudinally around said reinforcing element, and connected to said inner liner, wherein the one or more longitudinal strands are fixed to the outer jacket and/or the tubular inner liner, and wherein the sheath has an outwardly flared proximal end and the one or more longitudinal strands extend proximally beyond the outwardly flared proximal end. - View Dependent Claims (9, 10, 11, 12)
