The invention relates to an apparatus (1) for producing a peripheral groove (101) in an end portion (103) of a metal tube (100), in particular a metal tube (100) which is to be coated on the inside, the groove (101) being set up for receiving tube connectors, having a first, rotationally driven roller (3), a second, freely rotating roller (5), the first roller (3) having a roughened or structured surface (6) relative to the second roller (5), a pressing device (15) for producing a relative movement between the first and second roller (3, 5), between a first and a second position, the rollers (3, 5) assuming a first spacing from one another in the first position, which first spacing permits an introduction of a wall of the tube between the rollers (3, 5), and assuming a smaller, second spacing from one another in the second position, which second spacing is smaller than a material thickness (M) of the wall of the tube. It is proposed according to the invention that the first, driven roller (3) is set up to grip the tube from the outside in the second position and to rotate it, with the result that a peripheral groove (101) is pressed into the tube in the second position when the first roller (3) is driven.

An inner roller used for roll forming pipe elements has a flange extending radially from a body. The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming.

A cable assembly includes an elongate conductor surrounded by an outer insulator and an outer ferrule surrounding a portion of the conductor. An outer surface of the outer ferrule is deformed to produce an indentation having an indentation surface that is angled relative to the outer surface. The indentation forms a barb that at least partially penetrates the outer insulator. A method of manufacturing the cable assembly and a tool for forming the outer ferrule is also presented and described.

An assembly includes an elongate conductor, such as a coaxial electrical cable, having a generally circular cross section and a generally cylindrical seamless outer ferrule having a ferrule radius surrounding a portion of the conductor. The outer ferrule is deformed to define four indentations and four projections that are evenly spaced about a circumference of the outer ferrule. The four indentations have a consistent indentation radius that is less than the ferrule radius.

A multi-section quick assembly handle includes a multiple tubular members made of a permanently formable material having a threaded and friction fit connection.

A device for crimping a radially expandable and collapsible prosthetic valve comprises a coiled wire frame having a longitudinal opening extending from a proximal end to a distal end thereof. The opening has a first state and a second state, the opening in the first state having a first diameter dimensioned to receive the prosthetic valve in an expanded or partially crimped configuration therein, and the opening in the second state having a second diameter dimensioned to receive the prosthetic valve in a crimped configuration. The coiled wire frame has a first end coupled to a first member and a second end coupled to a second member. The first member is movable relative to the second member to convert the coiled wire frame from the first state to the second state.

A multi-component quick assembly handle includes a first tubular member made of a permanently deformable material and having a first end permanently formed with a predetermined diameter (x) and connecting to a second end forming a remaining portion of said first tubular member of a smaller diameter (xa), a second tubular member made of a permanently deformable material having a first end with a predetermined diameter (x) and connecting a second end having a larger diameter (x+b) and an inner diameter (y) to complementary receive by way of a friction fit said second end of said first tubular member. A method of forming multi-component quick assembly handle employs male and female tools to accomplish this.
