A stent retractor/distractor includes a radially flexibly enlargeable, pipe-shaped sheath which is divided up in the circumferential direction in at least two sections, namely one stiffening section and one enlarging section with differing radial flexibilities, which are connected with each other in one piece of material. The stent retractor/distractor defined in that way is made on the whole by a laser or water jet cutting procedure, preferably from a pipe blank.

Stent retractor/distractor

A stent retractor has a radially flexibly expandable tubular sheath divided in the peripheral direction into at least two sections, specifically a reinforcing section and an expanding section, with radial flexibilities that differ from one another, these sections being interconnected integrally. The stent retractor includes axial segments that are connected by a puzzle-type connection allowing simple separation or length adjustment in the axial direction (including when in situ) while also being made integrally, for example by a laser or water jet cutting method, preferably from a tubular blank.
