A novel prosthetic valve is described herein, as well as methods of making such novel prosthetic valves.

Method and apparatus are disclosed for mechanically opening a heat-bonded connection site between two hollow, flexible, thermoplastic segments of a medical fluid flow path, the heat-bonded connection site having an axis. The connection site is compressed between two facing surfaces, and the facing surfaces are relatively moved to rotate the connection site about the connection site axis and to apply force to the connection site substantially perpendicular to the connection site axis.

A profile includes: a sidewall, a lumen for a fluid path, and an end, the profile including a thermoset material, wherein the profile includes a sealed end without an external bonding material, wherein the sealed end withstands a seal integrity pressure test of at least 1 psi, such as at least 5 psi, such as at least 10 psi, such as at least 15 psi, or even at least 20 psi air pressure for about 30 minutes under dry and wet conditions.

A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

A padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), has a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The padding device is formed by injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system and a respirator with the carrying belt system are provided with the belt system having the padding device.
