Abstract

Apparatus is provided for insertion into a lumen of a body of a subject. The apparatus includes a sheath, the sheath including at least one section which is reinforced by braiding. The section extends longitudinally along at least a portion of the sheath. The sheath also includes at least one section which is substantially not reinforced, which extends longitudinally along at least the portion.

Claims

1. Apparatus for insertion into a lumen of a body of a subject, comprising a sheath, the sheath comprising:

at least one section which is reinforced by braiding, the section extending longitudinally along at least a portion of the sheath; and

at least one section which does not comprise any reinforcing elements, extending longitudinally along at least the portion,

wherein the at least one section which is substantially not reinforced comprises a splittable seam.

2. Apparatus according to claim 1, wherein the seam is adapted to open responsive to application of lateral tension thereto.

3. Apparatus according to claim 1, wherein the sheath is adapted to be inserted into a blood vessel.

4. A method for removing a sheath from a lumen of a body of a subject, comprising:

withdrawing the sheath from the lumen so that a segment of the sheath is outside the body, the sheath having at least one longitudinal section thereof which is reinforced by braiding, and at least one longitudinal section thereof which does not comprise any reinforcing elements; and

applying tension to the non-reinforced section, so as to split the sheath longitudinally at the non-reinforced section.

5. A method according to claim 4, wherein applying the tension so as to split the sheath comprises splitting the sheath along a seam of the at least one longitudinal section which is substantially not reinforced.
