The invention relates to a medical device, in particular a stent, having a radially self-expandable lattice structure (10) which is tubular at least in some sections and which is made of a single wire (11), which is interwoven with itself and which comprises a core material (11a) which is visible under X-ray and a superelastic jacket material (11b) and forms meshes (12) of the lattice structure (10). The invention is characterised in that a plurality of meshes (12) arranged directly adjacently in the circumferential direction of the lattice structure (10) form a mesh ring (13), and the lattice structure (10), in a fully self-expanded state, has an expansion diameter D.sub.exp, the mesh ring (13) having a mesh number n, and the core material (11a) having a core diameter d.sub.Kern, and the following being true for the core diameter d.sub.Kern: d.sub.Kern=f.Math.(D.sub.exp/n), with the following being true for a visibility factor f: 0.05≤f≤0.08.

A gastric vest system for treating excessive weight or obesity in mammals. The gastric vest system may include a trapezoidal-shaped vest having a left edge, a right edge, an upper indentation, and a lower indentation, and the trapezoidal-shaped vest is configured to be wrapped around a stomach or a modified stomach of a mammal to cover a lesser curvature and a greater curvature of the stomach or the modified stomach.

The invention concerns methods of delivering a hydrogel to the heart, comprising: introducing a hydrogel composition into a subject, said hydrogel comprising components mixed prior to introduction; the introducing being performed such that the hydrogel composition resides between the epicardium and the pericardium of the subject. In some embodiments, the injection is performed using a syringe or catheter.

A stent is formed of at least a cobalt-based alloy. The cobalt-based alloy may include 10-35 weight % metal member selected from the group consisting of platinum (Pt), gold (Au), iridium (Ir), osmium (Os), rhenium (Re), tungsten (W), palladium (Pd), tantalum (Ta), and combinations thereof; 16-21 weight % chromium (Cr); 9-12 weight % molybdenum (Mo); 0-25 weight % nickel (Ni); and balance cobalt (Co). The cobalt-based alloy may be a thin outer shell of a hollow stent. The cobalt-based alloy may be used to form at least one of an inner core and an outer shell of a core-shell structure of a stent. The cobalt-based alloy may be used to form an end of a wire for forming a stent.
