Suture collar with a flexible constraining means

摘要

A device for fastening an electrode in the pacemaker bed before the entry of the electrode into a vein is provided, and includes a sheath having two parts and, with a hose extending through their interior. The two parts and of the sheath are profiled at the contacting edges of a common separating point so that they are fixed in reference to one another in the rotational direction until a user pulls them apart beyond the axial extension of the profiling. In this pulled-apart position the parts of the sheath can be rotated in reference to one another under torsion of the hose and subsequently, due to the restoring force of the hose, will be again guided together axially, which reduces the interior cross-section of the hose and allows a form-fitting grasping the electrode extending therethrough.
