Publication number: 20080289389Abstract: A forming device includes an input including wire in an unformed state. The forming device has a forming station configured to receive the wire, the forming station comprising a plurality of forms, each independently movable toward and away from the wire such that the forms collectively bend the wire into a formed state that is periodic and defines a wavelength.Type: ApplicationFiled: May 27, 2008Publication date: November 27, 2008Inventors: Bradley A. Fitch, Mark A. Kempf, Anthony M. Harrison

Publication number: 20030093060Abstract: A catheter assembly defines a lumen. The catheter assembly includes a tight wound spring coil comprised of a lubricious coil material wherein the spring coil defines the lumen and has an outer surface. A wrap is wound about the outer surface of the spring coil. An exterior coating covers the spring coil and the wrap.Type: ApplicationFiled: November 9, 2001Publication date: May 15, 2003Applicant: Vadnais Technologies CorporationInventor: Mark A. Kempf

Patent number: 5542505Abstract: A torque limiting device that includes a shaft and a wrap extending around the shaft. The wrap is frictionally engaged with the shaft, and the wrap has an inner and an outer surface. The device further includes a restraining mechanism enclosing the wrap such that there is contact between the restraining mechanism and the outer surface of the wrap, and such that the restraining mechanism prevents the wrap from rotating relative to the retraining mechanism as the shaft is rotated in either one of two opposing rotational directions.Type: GrantFiled: May 26, 1995Date of Patent: August 6, 1996Assignee: Vadnais Technologies CorporationInventor: Mark Kempf

Patent number: 5477715Abstract: An apparatus includes means for feeding a wire from a fixed outlet against a coiling surface having a variable location in relation to the fixed outlet. The fixed outlet directs the wire in a path and the wire is deflected from the path by the coiling surface to bend the wire. The wire is monitored and output signals indicative of a physical characteristic of the deflected wire are generated. A controller receives the signals and generates control signals as a function thereof. An actuator, responsive to the control signals, adjusts the location of the coiling surface such that the physical characteristics are substantially uniformly maintained during the forming of the spring.Type: GrantFiled: November 16, 1994Date of Patent: December 26, 1995Assignee: Reell Precision Manufacturing CorporationInventor: Mark A. Kempf

Patent number: 5454249Abstract: Apparatus for forming a spring having a spring body and first and second generally axial toes from a wire is disclosed. The apparatus includes mechanisms for feeding the wire from a fixed outlet, wherein the fixed outlet directs the wire in a path; bending a first length of wire fed from the fixed outlet to form a first generally axial toe; bending a second length of wire fed from said fixed outlet to form a spring body; and bending a third length of the wire fed from the fixed outlet to form a second generally axial toe. The wire is then clipped after the formation of the second generally axial toe to separate the spring from a remaining portion of the wire. A method of forming such a spring is also disclosed.Type: GrantFiled: November 21, 1994Date of Patent: October 3, 1995Assignee: Reell Precision Manufacturing CorporationInventors: Mark A. Kempf, Sean M. Frost
