Medical valve implant for implantation in an animal body and/or human body

A medical valve implant comprising:

• an implant structure that is fastened to a base body, the base body comprising cells that extend in a circumferential direction of the valve implant, wherein an end section of the base body bulges in a curved shape outwardly in a radial direction of the base body, wherein the end section has a larger diameter than an axially adjacent collar portion of the base body, wherein the collar includes a first cell structure composed of a plurality of cells, which is provided to form, in an intended end state, an intended inner cross-section of the base body that is matched to an intended outer cross section of the implant structure;
• and
• a holding device extending axially from and beyond the cells, the holding device comprising a leg directly connected to a terminal end of one of the cells and a head at an opposite end of the leg, wherein one or both of the leg and the head is canted radially inward toward a geometric center of the base body.
