Definitions
- the present invention relates to a connector for connecting cardiac support systems to the left and right atria as well as the ascending aorta and the pulmonary artery.
- a device for connecting probes and cannulas to blood vessels in which the cannula is attached to one another by means of two rings which are screwed together, one of which is inserted into the vessel.
- CA 2425915 AI a medical drainage device is known which has a tube which is guided through the wall of a vessel and into which a further tube is screwed.
- the invention is therefore based on the object of developing a connector which enables seamless connection of cardiac support systems, the flow conditions in the lumen of the blood vessels not being changed.
- This object is achieved according to the invention in that a tubular support changes into a trumpet-shaped enlargement adapted to the curvature of the inner wall of the blood vessel, the connection is provided with an external thread in its area adjacent to the enlargement, and a perforated disk is provided which is connected to the external thread of the connection screwing internal thread is provided.
- the device according to the invention Due to the trumpet-shaped opening of the connector socket and the fact that significantly less foreign material is introduced into the blood vessels than with conventional cannulas, the device according to the invention has a negligible thrombogenicity and thus a risk reduction of embolisms in the organism with corresponding failures, e.g. neurological type (hemiplegia, blindness, speech loss, etc.).
- the fixation of the connector in the tissue leads to absolute blood-tightness and, due to the spike-like anchoring, is much more gentle on the tissue than a large-area tissue contact with increased contact pressure. This avoids tissue necrosis with subsequent leakage and bleeding.
- a special stylet can be inserted into the body by the connector, which ensures a secure closure in the area of the connector, so that blood clots are no longer deposited here either and explantation of the connector is no longer necessary.
- Fig. 1 the connector connected to a blood vessel
- Fig. 2 the connected to a blood vessel and closed with a stylet
- the tubular connector (10) is connected to the lumen of a blood vessel, for example the auricle, and with the axially parallel spines (20), which are located on the outside of the trumpet-shaped extension (12), in the vessel wall (30) anchored.
- the outside of the trumpet-shaped extension (12) is on the curvature of the inner wall of the blood vessel be (16) a peripheral depression facing the vessel wall, which is located at a position corresponding to the spikes (20) on the outside of the trumpet-shaped extension (12) of the connector (10).
- the connector is connected to cardiac support systems via a supply line (28), the supply line also being able to represent another blood vessel.
- Fig. 2 shows the connector closed by a stylet (26).
