A guide wire control device and methods of use are described herein. A novel method for optimizing a guide wire for a patient is described. The method includes steps of scanning a patient's anatomy and then fabricating, or selecting, a guide wire with optimal geometry for a particular patient and/or procedure. The guide wire may optionally be secured to a guide wire control device for improved control during transcatheter surgical procedures.

Patient specific guide wire method

A hatch cover lock comprises a front member including a pair of flanges, a rear member positioned between the pair of flanges; a gap defined between front member and the rear member; a clamp defining a J-shaped cross-section in a plane normal to a length thereof, the clamp having one leg thereof disposed in the gap and having another leg thereof disposed parallel to an outer surface of the rear member and at a distance therefrom, a handle, a first pivotal connection between the handle and the front member, a gravity lock, a second pivotal connection between the gravity lock and the handle, and a weld-free connection between the main portion of the rear member and the main portion of the front member.

Hatch cover lock

A guide wire control device and methods of use are described herein. A guide wire is retained by a lock mechanism to a sliding assembly. The sliding assembly controllably moves within a stationary assembly. The guide wire control device provides improved control of guide wires during transcatheter surgical procedures.

Catheter guide wire control device

A guide wire control device and methods of use are described herein. A guide wire is retained by a lock mechanism to a translating assembly within a stationary tubular structure. A rotating actuator controls the translation of the translating assembly and resulting guide wire. The guide wire control device provides improved control of guide wires and angles of a deployment capsule during transcatheter surgical procedures.

Integrated catheter guide wire control device

A brake actuator assembly for a railway vehicle braking system includes a pair of end members spaced apart from each other along a longitudinal axis of the brake actuator assembly, a hollow flexible elastomeric member, two peripheral flanges extending outwardly from ends of the hollow flexible elastomeric member. Two retaining members, apertures and fasteners are employed for attaching each peripheral flange directly to a respectively positioned end member. The brake actuator assembly is connected to a source of fluid under pressure enabling inflation of the flexible elastomeric member and initiation of a braking sequence of the railway vehicle braking system. The brake actuator assembly of the instant invention allows for improved control of the brake shoe forces including visual travel measurement indication which is especially desirable during light load conditions. Currently used brake assemblies employing cylinder type actuators may be retrofitted with the brake actuator assembly of the instant invention.

Universal brake assembly

A compressible spring for at least absorbing and dissipating energy includes a plurality of elastomeric pads disposed coaxially and in series with each other and a plurality of separator plates, with each plate being disposed between a pair of the adjacent pads. A plurality of first prongs are formed integrally with or secured to a first surface of each separator plate for attaching the plate to one pad and a plurality of second prongs are formed integrally with or secured to a second surface for attaching the plate to an opposed pad. An axial aperture is also formed through each plate with prongs positioned in an alternating manner on a peripheral edge of the axial aperture. Projections may be also provided on each surface of the plate and adapted with an axial aperture that continues through the plate for additional attachment of the plate to the pair of pads.

Compressible elastomeric spring

A method of making a compressible elastomeric spring including at least one compressible elastomeric pad enclosed by a pair of metal plates includes the steps of forming plates with a center aperture and a plurality of prongs positioned about a peripheral edge thereof, forming each end of the pad with an axial projection and abutting groove, aligning the plurality of prongs with each respective projection and respective groove and applying axial force to one end of the spring to frictionally interlock the plurality of prongs with such projection and groove. The method also provides for making a multi-tiered stack of pads separated by plates in the above described manner and pre-shortening the spring prior to installation into the conventional yoke. The above described method additionally improves axial straightness and lateral stability of the multi-tiered spring assembly.

A parking brake assembly for a railway car includes a ratchet mounted for rotation on a threaded piston rod of a brake actuator and a holding pawl engageable with the ratchet for maintaining a push rod of the parking brake assembly to apply braking force when the air pressure is lost in the brake pipe and releasing the push rod to accordingly release the braking force when the supply of air pressure in the brake pipe is restored. An operating lever and a cylinder connected thereto are provided for selectively rotating the holding pawl. Valve is provided for supplying air pressure to and evacuating it from the cylinder. Release mechanism is provided for manually releasing the braking force. The parking brake assembly is employed with either truck-mounted or carbody-mounted braking system.

A compressible resilient elastomeric pad includes a body defining a central axis, the body formed from a predetermined material and having each of a peripheral side surface, a first axial end and a second axial end, each of the first and second axial ends having a flat surface thereof disposed normal to such central axis. A first raised projection is centrally formed on the flat surface of the first axial end and a second raised projection is centrally formed on the flat surface of the second axial end. A first groove is formed in the flat surface of the first axial end in abutting relationship with a peripheral side surface of the first projection and a second groove is formed in the flat surface of the second axial end in abutting relationship with a peripheral side surface of the second projection.

A draft gear assembly which is mountable within a yoke of the railway vehicle for cushioning buff and draft dynamic impact forces encountered during make-up and operation of a railway vehicle includes a compressible spring positioned intermediate the front coupler follower and the rear follower in alignment with the longitudinal axis of the yoke. A pair of axially aligned compressible springs may be also provided being either separated by a center plate or by a wall of the yoke.

Combination yoke and elastomeric draft gear

A draft gear assembly for cushioning buff and draft dynamic impact forces being applied to a center sill member of the railway vehicle during make-up of a train consist and in-track operation of such train consist includes a resilient cushioning member and a friction mechanism both axially mounted within the yoke with the friction mechanism positioned between the front end of the resilient cushioning member and the front coupler follower. A pair of the resilient cushioning members with the friction mechanism mounted therebetween may also be provided.

Combination yoke and elastomeric draft gear having a friction mechanism

A draft gear assembly for cushioning both buff and draft dynamic impact forces being applied to a center sill member of a railway vehicle includes a housing member closed at one end and open at an opposed end, the housing member having a rear portion adjacent the closed end and a front portion adjacent the open end. At least one compressible elastomeric spring is positioned within the rear portion and has a rear end thereof abutting at least a portion of an inner surface of the closed end. A friction clutch mechanism is also provided in abutting engagement with each of the front end of the compressible elastomeric spring and the coupler shank. The housing member may be provided with a pair of ledge portions disposed intermediate its ends and attachment members disposed on the open end for attaching the housing member directly to the coupler shank.
