Benefits of technology
The patent text talks about using a coating on medical implants to reduce friction when they are inserted into catheters. The coating can make the implant easier to move and can be applied quickly, accurately, and easily.
Problems solved by technology
However, an occluder having an internal fabric or a membrane attached outside may be difficult and time-consuming to produce.
Moreover, the use of artificial fibrous material in an occluder may lead to blood clotting or thrombosis.
If the clotting is too severe and the clot breaks free, the clot may travel to other parts of the body.
The most serious complication of a deep vein thrombosis is that the clot could dislodge and travel to the lungs, which is called a pulmonary embolism.
The consequences of such a blockage may be severe.

The disclosure relates to a medical implant (1) for occluding an opening in a body and a method of producing such a medical implant. Disclosed is an improved occluder (1), which provides improved occlusion, improved sealing and improved endothelialization. The occluder slows down the blood flow through the defect. In one embodiment, a medical implant (1) for occluding an opening in a body is provided, wherein the medical implant (1) comprises a body mesh of strands forming a plurality of adjacent cells delimited by the strands, the body mesh having an external surface, and a coating (22) or a non-fibrous film membrane (17) covering the external surface for at least partly restricting a fluid flow through a structural tissue defect, such as a defect in the heart.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Disclosure[0002]This disclosure pertains in general to the field of medical implants. More particularly, the disclosure relates to occluding devices or occluders. In particular the disclosure relates to applying of a coating to an external surface of a medical implant or to coverage of an outside of a medical implant with a coating or a non-fibrous film membrane for improving the sealing of a defect, such as a defect in the heart.[0003]2. Description of the Prior Art[0004]An occluder is a medical product or implant used for occluding, i.e. closing, defects e.g. in the human heart. Defects may occur in various regions of the heart and have different forms. Defects in the septum of the atrium are common. The occluders can be inserted using minimally invasive cardiac catheter techniques, more precisely by means of a transvenous, catheter-interventional access. One type of occluders is made of Nitinol threads, e.g. having a double disc sh...
