Problems solved by technology

The prior art also suffers from a lack of long-term stability, i.e. fatigue of the occluder assembly due to cardiac activity, and a short-term stability problem during implantation, which is limited by an implant that remains flexible during implantation. object challenge
Furthermore, previous methods of providing flow restriction devices external to the occluder were complex and time consuming

Abstract

The disclosure relates to a medical implant for occluding an opening in a body and a method of producing such a medical implant. Disclosed is an improved occluder, which provides improved occlusion, improved sealing and improved endothelialization. A method is disclosed comprising braiding, knitting or weaving together strands to form a body mesh of strands forming a plurality of adjacent cells delimited by the strands. The method further comprises applying a first coating to said strands, and applying a second coating to at least part of an external surface of said medical implant, wherein said first coating provides a binding force to said second coating such that said second coating adheres to said strands.

Description

technical field [0001] The present disclosure relates to the field of medical implants in general. More specifically, the present disclosure relates to occlusion devices or occluders. In particular, the disclosure relates to applying a coating to the surface of a medical implant to cover the outside of the medical implant with a coating or covering for improved sealing of defects, such as defects in the heart. Background technique [0002] An occluder is a medical product or implant that is used to occlude (ie close) a defect, such as a defect in the human heart. Defects can occur in different areas in the heart and take many forms. Common is a septal defect in the atrium. The occluder can be inserted using minimally invasive cardiac catheterization techniques, more specifically catheterized access through a vein. One type of occluder is manufactured from Nitinol wire, for example in the shape of a double disc with a central tubular portion having a smaller diameter betw...
