Deconstructable endoluminal devices and related systems and methods

An introducer sheath, said introducer sheath comprising:

• a tubular member comprising a wall,
• a reinforcement member disposed between a plurality of layers of the wall, and
• a perforation through the wall that is offset from, yet in phase with, a pattern exhibited by the reinforcement member,
• wherein application of an axial force to an end of the reinforcement member causes the wall to be torn along the perforation.

An introducer sheath, said introducer sheath comprising:

• a tubular member comprising a wall, and
• a reinforcement member disposed between a plurality of layers of the wall,
• wherein the reinforcement member comprises a continuous elongate element that provides 360 degree radial support along substantially the entire length of the tubular member, and
• wherein application of an axial force to an end of the reinforcement member causes the reinforcement member to be torn through the wall.

A method of safely removing an endoluminal device from a subject's vasculature comprising the steps of:

• applying axial and rotational forces to an introducer sheath to determine whether it is attached to a vascular wall of the subject's vasculature;
• if the introducer sheath is determined to be attached to the vascular wall, applying an axial force to an end of a reinforcement member of the introducer sheath to separate it from a wall of a tubular member of the introducer sheath;
• intermittently, during said step of applying the axial force to the end of the reinforcement member of the introducer sheath, applying axial and rotational forces to the introducer sheath to determine whether it remains attached to the vascular wall;
• and
• removing the introducer sheath from the subject's vasculature once it is no longer attached to the vascular wall.
