Abstract: The invention relates to a delivery system for delivering a stent (S) into a body vessel of a patient, comprising a flexible catheter tube (3) having a proximal and a distal end for delivering the stent (S) to a predetermined location in the body vessel and a catheter tip (1) having a longitudinal direction, which is disposed at the distal end of the catheter tube (3). The catheter tip (1) has a stent chamber (150) to receive the stent (1). The catheter tip has a first pressure chamber (20, 22). In the catheter tube (3) a first fluid channel (31) extends from the proximal end to the first pressure chamber (20, 22) of the catheter tip (1). The volume of the first pressure chamber (20, 22) can be enlarged by delivering a first fluid from the first fluid channel (31) to the first pressure chamber (20, 22), such that the stent (S) is released from the stent chamber (150) at the predetermined location in the body vessel.

Abstract: A catheter for measuring a flow of blood through a body tissue comprises a light emitter for emitting light into the body tissue and at least one light receiver for receiving light reflected in the body tissue and back to the catheter. The light emitter and the at least one light receiver are arranged in the catheter, wherein the catheter comprises a middle piece and a first and a second connection tube. The middle piece has a distal fastening piece for fastening to the first connection tube and a proximal fastening piece for fastening to the second connection tube, wherein the light emitter and the at least one light receiver are arranged in the middle piece.

Abstract: A device for measuring the blood flow of a body tissue comprises a catheter having a catheter head for the insertion into the inside of a body tissue and a center piece having a light emission surface, out of which an optical conductor leads, and having a reflection surface, which is disposed opposite of the light emission surface and oriented obliquely to the longitudinal axis of the optical conductor. The optical conductor is disposed such that an emitted light beam is directed at the reflection surface, the emitted light beam can be deflected at the reflection surface and reflected into the body tissue, and a reflected light beam can be reflected out of the body tissue at the reflection surface and fed into the optical conductor. The catheter head is divided into an insertion region and a connecting region, wherein the insertion region comprises a plurality of recesses on the surface thereof. In the direction of the connecting region, the insertion region has an increasing diameter.

Abstract: The invention relates to an occluder for closing a passage in a circulatory system comprising an expandable fixation unit for fixing the occluder on the passage, wherein the occluder can be transferred in the passage from a compact appearance into an expanded appearance. The occluder has a distal and a proximal axial part, in which the fixation unit is pivotally held. According to the invention, the fixation unit comprises distal fixation arms and proximal fixation arms, wherein the distal fixation arms are pivotally held in the distal axial part and the proximal fixation arms are pivotally held in the proximal axial part. The distal and the proximal fixation arms have free ends, which are interconnected by means of connecting members that can be moved relative to the fixation arms, wherein in each case a distal fixation arm is connected to a proximal fixation arm located diagonally opposed thereto. Said occluder is suited in particular for closing a ventricular septal defect (VSD).

Abstract: An anchoring device for anchoring a line in a skull bore hole comprises a base part and a cover that tightly closes the base part. The base part has a fastening element for fastening the base part in the bore hole and a passage opening for feeding the line from the bore hole to an outside of the anchoring device. A contact surface extending between the bore hole and the outside for laying the line is present in the base part. The contact surface is curved in a constant direction so that the line is guided from the skull interior to the outside in a constant direction and at a radius of curvature that is greater than or equal to a predefined minimum radius of curvature. Said anchoring device allows a line to be lead out of a bore hole of a skull at a flat angle without the line being bent too greatly or even kinked.
