    摘要： A method for producing a porous metallic structure comprising a metal element from a metal salt comprising a cation part and an anion part, comprising the steps of: providing a volume of metal salt; exposing the volume of metal salt in an atmosphere comprising a reduction gas at a temperature below a melting temperature of the metal element, leading to converting the volume of metal salt into the porous metallic structure by removing the anion part using the reduction gas; wherein the porous metallic structure has a pore size between 1 nanometer and 50 micrometer, and a ligament size between 1 nanometer and 50 micrometer; wherein the ligament size is controlled by the temperature during the exposing.

    摘要： The invention is directed to a method and a surgical instrument, typically a surgical stapler that is configured for performing anastomosis of a first gastro-intestinal tract section to a second gastro-intestinal tract section, both gastro-intestinal tract sections comprising a superficial layer and an intermediate layer. Said method comprises contacting the superficial layers of said gastro-intestinal tract sections and compressing the contacted sections between a first pressure area and a second pressure area, wherein the sum of the first pressure area and the second pressure increases during the compression such that the superficial layers are pressed aside and the intermediate layers are contacted.

    摘要： A prosthetic heart valve having a pair of cooperating leaflets mounted in a valve body to alternate between an open position where the flow of blood in a downstream direction is permitted and a closed position where the flow of blood in the reverse direction is counteracted. Pivot member sets at diametrically opposite sides of each leaflet guide the leaflets moving between the open and closed positions, each set including an ear or a recess cooperating with an associated cavity or knob of an interior surface of the valve body. Each ear or recess bounds at least one leaflet passageway through that ear or recess and located spaced from upstream and downstream ends of the ear for allowing flow through that ear and the associated cavity, or through that recess, when the leaflets are in the closed positions.
