Publication number: 20130233160Abstract: A tubular braid and mechanisms for forming the braid are described. The mechanism for braiding includes a disc, a mandrel, a plurality of catch mechanisms, and a plurality of actuators. The disc defines a plane and a circumferential edge. The mandrel extends from a center of the disc and is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc. The plurality of catch mechanisms are positioned circumferentially around the edge of the disc and are adapted to engage a filament. The plurality of actuators are configured to move relative to one another and are adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc.Type: ApplicationFiled: April 26, 2013Publication date: September 12, 2013Applicant: SEQUENT MEDICAL INC.Inventors: PHILIPPE MARCHAND, JOHN NOLTING, DARRIN J. KENT, TAN Q. DINH, HUNG P. TRAN, JAMES A. MILBURN, JAMES M. THOMPSON

Patent number: 8430012Abstract: A device and method for forming a tubular braid comprising a plurality of filaments. The braiding machine comprises a disc with a mandrel extending from the center in a perpendicular direction and a plurality of catch mechanisms arranged circumferentially around the edge of the disc. A plurality of filaments are temporarily affixed to the mandrel, each filament extending from the mandrel toward the edge of the disc and engaging the edge of the disc at a discrete point of engagement. The plurality of catch mechanisms are attached to actuators adapted to move the catch mechanisms in a generally radial direction relative to the edge of the disc to allow the catch mechanism to engage a subset of the filaments and move the engaged filaments beyond the circumferential edge of the disc.Type: GrantFiled: August 9, 2012Date of Patent: April 30, 2013Assignee: Sequent Medical Inc.Inventors: Philippe Marchand, John Nolting, Darrin J Kent, Tan Q Dinh, Hung P Tran, James A Milburn, James M Thompson

Publication number: 20130092013Abstract: Devices and methods for forming a tubular braid comprising a plurality of filaments. The braiding machine includes a circular array of filament guiding members defining a plane; a mandrel defining an axis and adapted to carry one or more filaments extending from the mandrel to the circular array; a plurality of filaments extending from the mandrel in a radial array; a plurality of actuator mechanisms disposed operably about the disc; and a rotating mechanism adapted to rotate one or more filaments. The actuator mechanisms and rotating mechanism are configured to move each of the one or more filaments about the mandrel axis in a path comprising a series of arcs and radial movements. The braiding machine may alternately first and second annular members, a mandrel, first and second plurality of tubular wire guides, and a plurality of wires extending from the mandrel.Type: ApplicationFiled: September 10, 2012Publication date: April 18, 2013Inventors: JAMES M.

Patent number: 5242438Abstract: A method and device are provided for directing laser radiation to a body cavity site. A hollow, elongate, optical fiber is advanced, usually in a containing device, to the vicinity of the site and coupled to a laser source with a distal end region of the fiber extending along a longitudinal axis. The fiber terminates in an energy delivery surface for emitting laser radiation transmitted by the fiber. The radiation is intercepted at a location axially aligned with the energy delivery surface and is reflected in a beam radiating substantially transversely of, and substantially circumferentially around, the axis. A reflector member or block is provided for reflecting the radiation and is mounted in an open end of the catheter at a selected axial position along the axis. A fluid, such as a flushing fluid, can be directed between the end of the fiber, against the reflector member, and to the body site.Type: GrantFiled: April 22, 1991Date of Patent: September 7, 1993Assignee: Trimedyne, Inc.Inventors: Vahid Saadatmanesh, Hany M. G. Hussein, Marvin P. Loeb, Stanislaw Sulek, James A. Milburn

Patent number: 5179610Abstract: A coupling system for coupling a beam of radiant energy from a laser to a fiber optic cable includes a secondary transmission path which surrounds the input end of the fiber optic cable and provides an optical path for energy which is not transmitted by the fiber optic core but is lost. Displaced from an output end of the secondary transmission path is a multi-faceted reflector. The reflector is displaced sufficiently from the output end of the secondary transmission path so that the power density of the radiation incident thereon is reduced sufficiently so as to not damage the facets thereof. The coupling system is contained within a heat sink which receives the reflected and lost radiant energy harmlessly converting same to heat.Type: GrantFiled: April 19, 1991Date of Patent: January 12, 1993Assignee: Trimedyne, Inc.Inventors: James A. Milburn, Vahid Saadatmanesh, Raymond Dessoffy, L. Dean Crawford, Hany M. G. Hussein

Patent number: 4974789Abstract: A dispensing package for a fiber-optic cable comprised of two mating members and a separator disposed therebetween. The two mating members have centrally located openings and are joined at their mating edges and define a cavity therebetween. The separator is secured between the mating members to divide the cavity into first and second cable receiving chamber. Each cable receiving chamber accommodates a circularly coiled cable portion. A fiber-optic cable passes through the separator and opposite cable ends exit respectively from the central apertures of each mating member to allow cable to be payed out from opposite sides of the package. A series of apertures in the mating members and separator define a plurality of flow passages through the package for sterilization purposes.Type: GrantFiled: June 29, 1989Date of Patent: December 4, 1990Assignee: Trimedyne Laser Systems, Inc.Inventor: James A.
