STABILIZER FOR OPERATIONS ON THE BEATING HEART

摘要

The present application discloses a stabilizer for operations on a heart, preferably on a beating heart, with a fastening shaft and a tissue contact component with two substantially parallel, elongated bearing elements which are provided on a base section and are adapted to be arranged on two opposing sides of a blood vessel (B) such that at least one section of the blood vessel (B) runs between the two bearing elements, wherein the base section of the tissue contact component is affixed to one end of the fastening shaft. At least one bearing element has a slit which extends in the longitudinal direction of the bearing element at least over a section thereof, and the fastening shaft has an axially proceeding channel which extends at least over a section of the fastening shaft and is connected to at least one connecting channel in the region of the end of the fastening shaft on which the base section is mounted, the connection channel connecting the axially proceeding channel to the surroundings, wherein the axial end of the fastening shaft is preferably closed. Preferably, an aspiration device is provided on the stabilizer and is releasably attachable to the fastening shaft, in particular by being pushed onto the fastening shaft from its free end. The aspiration device has a connection component, with which the aspiration device can be fastened releasably on the stabilizer and which has a least one connection cavity, and at least one aspiration component which has an axially extending channel that is connected to the at least one connection cavity and which is adapted to be arranged at least partially in a slit of a bearing element when the aspiration device is mounted on the stabilizer.
