A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component may be the expiratory limb of a breathing circuit.

An endoscope includes a handle connected to a flexible, steerable, kink-resistant insertion tube. An endoscope insertion tube may include a shaft, a lower durometer section proximate to a distal end of the shaft, and a higher durometer section positioned between the lower durometer section and a medium durometer section. The endoscope insertion tube may further include a fourth thermoplastic laminate section proximate to a proximal end of the shaft and having a higher durometer. A method of making an endoscope insertion tube may include inserting a mandrel with one, two, or more lateral slots and a liner into a shaft, wherein the liner is positioned between the mandrel and the shaft, bonding a bonded portion of the liner to an inner surface of the shaft, separating other portion(s) of the liner from the shaft, and inserting a first deflection wire in a gap between the shaft and the unbonded portion(s) of the liner.

Disclosed is an injection molding method for a degradable intravascular stent with a flexible mold core structure. The injection molding method includes the following steps: Step 1, winding a metal rod with a flexible metal film, and applying an inward bending stress to the flexible metal film; Step 2, fixing the flexible metal film to the metal rod, and processing a complementary structure of the degradable intravascular stent on the surface of the flexible metal film; Step 3, performing injection molding processing: Step 4, ending the injection molding, removing the mating body of the flexible metal film and the metal rod and the degradable intravascular stent formed on the surface of the flexible metal film by injection molding, performing cooling, separating the metal rod from the flexible metal film, withdrawing the metal rod, and then removing the flexible metal film to obtain a formed degradable intravascular stent.

Disclosed herein are three-dimensional porous tubular scaffolds for cardiovascular, periphery vascular, nerve conduit, intestines, bile conduct, urinary tract, and bone repair/reconstruction applications, and methods and apparatus for making the same.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

The inventive method for making a medical device includes providing a micro plastic tube; molding a hub onto the tube; trimming the tube to a predetermined length; molding a tip onto the tube, and creating a tip that contains a micro orifice at a predetermined angle.

This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.

A control circuitry (11) comprises an adjustable capacitor (C1), and a bias source (111) configured to apply a bias voltage (V2) to said adjustable capacitor (C1) to adjust a capacitance value of the adjustable capacitor (C1). Such a control circuitry may for example be part of a sealing device (1) to seal a medical tubing (2), the sealing device (1) comprising a receptacle (100) to receive said medical tubing (2), the receptacle (100) comprising an electrode arrangement for causing a heat action on the tubing (2).
