Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal member having a proximal end, a distal end, and a proximal diameter. The guide extension catheter may additionally include a collar member attached to the distal end of the proximal member, the collar member comprising a base portion and one or more ribs connected to the base portion and extending distally away from the base portion. In still some additional embodiments, the guide extension catheter may further include a distal sheath member attached to the collar member, the distal sheath member having a distal diameter larger than the proximal diameter.

A method of molding a metalized composite part. The method comprises: introducing particles comprising at least one metal into a gas stream; directing the gas stream toward a surface of a thermoplastic composite part, thereby depositing a metal layer on the composite part to form a metallized composite part; and molding the metallized composite part to introduce a bend without delamination of the metal layer from the metallized composite part.

A method for producing a component includes incorporating a molding compound into a tool for producing the component, where the molding compound includes an artificial resin as a matrix and a filler material embedded in the matrix. The method includes compressing the molding compound by the tool and by the compressing forming the molding compound to a green product. The method further includes providing the green product while disposed in the tool with a layer in a sub-region by incorporating a liquid material for producing the layer into the tool and applying the liquid material to the sub-region. The liquid material is a metallic material and the layer is an electromagnetic shielding on the green product.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

A method for manufacturing optical and microwave reflectors includes: placing an assembly comprising a resin-infiltrated tendrillar mat structure on a mandrel; placing a pre-impregnated carbon fiber (CF) lamina on top of the tendrillar mat structure; placing the assembly in a vacuum device so as to squeeze out excess resin; and placing the assembly in a heating device so as to cure the tendrillar mat structure together with the CF lamina, forming the CF laminae into a laminate that combines with the tendrillar mat structure to create a cured assembly. A reflector suitable for one or more of optical and microwave applications includes: a mandrel; a resin-infiltrated tendrillar mat structure placed on the mandrel; and a pre-impregnated carbon fiber (CF) lamina placed on top of the tendrillar mat structure.

A one-surface groove for wiring is formed in a front surface 2a, opposite-surface grooves for wiring are formed in a back surface 2b by protruding core members, and communication parts for allowing the one-surface groove and the opposite-surface grooves to communicate with each other are formed to shape a board section 2 made of a non-conductive resin. After the core members are retracted, a conduction-side resin, which will become conductive, is shaped in the one-surface groove, the opposite-surface grooves, and the communication parts to form front-side wiring 3, communication wirings 4, and back-side wirings 5, whereby a wiring circuit component is provided.
