Abstract
The invention relates to a stent () for introducing into human body cavities, in particular into blood vessels, comprising a proximal first end to be introduced () and a distal final end to be introduced (), a sleeve-like stent body () made of biocompatible material, and at least one support wire () provided as a support body within the stent body (), the support wire (), when the stent is in the tensioned state, resting against the inside of the stent body () in the shape of a spiral and the stent body (), when the stent is in a compressed state, being collapsed and expandable into a tensioned state. The proximal end of the support wire () in the region of the proximal first end to be introduced () is firmly attached to the stent body () and the distal end of the support wire, when the stent is in the compressed state, extending from the distal final end () of the stent body () to be introduced. The support wire () is a shape-retaining spring wire which in the compressed state is pre-tensioned at least in the region of the stent body () and is drawn into an elongated straight line and contracts in the longitudinal direction into the spiral shape at least in sections upon closing of the spring and expands radially in the form of a spiral in order to effect a radial expansion of the contracted stent body () until it reaches the tensioned state.
