Abstract
A stent, in particular a coronary stent, comprising at least two tubular portions which are arranged adjacently in the longitudinal direction of the stent and which comprise a plurality of interconnected, substantially cell-shaped elements which have an orientation and are connected together in the longitudinal direction of the stent by way of at least one first connecting means, wherein the elements are of such an arrangement and/or configuration that the ends of the elements which are in the longitudinal direction of the stent define an edge contour extending around the stent in a wave-like configuration in the peripheral direction thereof, and wherein the mutually adjoining edge contours of two tubular portions extend around the stent substantially in in-phase relationship.
Claims41
A stent, comprising:
- at least two tubular portions, arranged adjacently in a longitudinal direction of the stent, each said tubular portion comprising a plurality of interconnected, substantially cell-shaped elements, the cell-shaped elements in adjacent tubular portions being aligned such that each cell-shaped element of a first tubular portion has a common central axis with a cell shaped element of a second tubular portion in a longitudinal direction of the stent, the adjacent tubular portions being connected together in the longitudinal direction of the stent by way of at least one first connecting bar that extends substantially parallel to the longitudinal direction, wherein the at least one first connecting bar directly connects cell-shaped elements of adjacent tubular portions,
- wherein the elements are of such a configuration that the ends of the elements which are in the longitudinal direction of the stent define an edge contour extending around the stent in a periodic wave-like configuration in a peripheral direction thereof, and wherein the mutually adjoining edge contours of adjacent tubular portions extend around the stent substantially in an in-phase relationship, and wherein the elements of at least one tubular portion are connected in the peripheral direction of the stent by way of second connected bars.
