A stent, in particular a coronary stent, for implantation in the region of vessel branchings, comprising a tubular casing with a proximal and a distal end, wherein in the implanted condition the proximal end is arranged in proximal relationship with the vessel branching and the distal end is arranged in distal relationship with the vessel branching, and at least one branching portion, which is arranged at the periphery of the casing and which is provided to open a passage into the branching-off branch of the vessel and which in the implanted condition is arranged in the region of the vessel branching, wherein the branching portion includes at least one first support element, which is provided for supporting the vessel transition and which can be pivoted substantially radially out of the peripheral surface and which extends from a first direction into the branching portion, and wherein the branching portion includes at least one second support element, which is provided for supporting the vessel transition and which can be pivoted substantially radially out of the peripheral surface and which extends into the branching portion from a second direction which is substantially opposite to the first direction.

Stent for vessel branchings

A balloon catheter for use in the region of a vessel branching and, in particular, in coronary vessels is provided. The catheter comprising a catheter stem disposed at the distal end of which are provided at least one balloon and at least one first guide means arranged in the region thereof for positioning the balloon in the region of a vessel branching. The first guide means is adapted to be introduced into the lateral branch of the vessel transversely with respect to the longitudinal direction of the balloon catheter. The balloon comprises at least two chambers which are spaced from each other in the longitudinal direction of the balloon catheter and between which the first guide means is arranged.
