A medical implant (), in particular a stent (), for implantation in an animal body and/or human body (), comprising a base body () which includes at least two segments (') having at least two deflection points () that are diametrically opposed in the axial direction (), and at least one adjusting means () that acts on the deflection points () to adjust an extension () of the base body () in the circumferential direction ().

Medical implant, in particular a stent, for implantation in an animal body and/or human body

A stent is provided having a base body circumscribing a cylindrical shape and radially expandable from a contracted starting position into a dilated support position, including a plurality of meander-shaped struts disposed in the circumferential direction and arrayed on one another in the axial direction, each strut being meander-shaped in its coarse structure and made of a flexible material, and at least one axial connector in the axial direction, connecting the meander-shaped struts of two axially adjacent meandering curves, wherein the at least one axial connector connects the inside radius of a zenith point of a first meandering curve with a second meandering curve, characterized in that the at least one axial connector at the inside radius of the zenith point of the first meandering curve has an at least double-arm structure.

Stent having improved stent design

A medical supporting implant, in particular a stent, comprises a tubular base body which is made up of bendable struts (), such that at node points () of at least two struts (), the bendable struts () form an acute angle (W) to one another which angle becomes larger on dilatation of the implant with plastic deformation of the struts () at the node point (). At least a portion of the struts () between the plastic deformation areas () is provided with a telescoping ratchet mechanism (R) for irreversible lengthening of the respective struts () on dilatation.
