Abstract: A catheter includes a catheter body defining first and second lumens, and a wire having first and second segments each with a greater stiffness, and a middle segment with a lesser stiffness. The wire is in an elastically deformed access state where the middle segment extends from an opening to the first lumen to an opening to the second lumen and forms a smaller loop. The wire is adjustable via sliding the first and second segments in opposed directions to an elastically deformed treatment state where the first segment extends from the opening to the first lumen to the opening to the second lumen and forms a larger loop.

Abstract: A hybrid wire guide is comprised of a distal segment of nitinol wire welded to a proximal segment of stainless steel wire. The stainless steel wire includes a flex transition segment that terminates at the weld, and defines a plurality of flexibility enhancing voids distributed in a pattern along a centerline so that a flexibility of the flex transition segment changes toward a match of a flexibility of the nitinol wire over a tracking segment that extends distally from the weld. The respective shapes of the flexibility enhancing voids change responsive to the flexure of the flex transition segment away from a straight configuration.

Abstract: A wire guide which may be used to cross a lesion through the subintimal layer of an intraluminal passage. The wire guide comprises an inner elongated member with a larger diameter proximal portion, a smaller diameter distal portion, and a tapered portion transitioning between the larger and smaller diameters. An outer shell surrounds the inner elongated member. The wire guide may be used to cross a lesion in an intraluminal passage through the subintimal layer while minimizing the portion of the wire guide which deflects against the proximal end of the lesion. Once the wire guide has crossed the intraluminal passage, it may be straightened so devices may be advanced to the lesion over the wire guide and used to clear the intraluminal passage.

Abstract: A spring action medical device includes a spring that may propel a hammer component in a distal direction when the spring is released from a loaded state. When propelled forward by the spring, the hammer component makes contact with a distal tip of the medical device. The distal tip may then transfer a force to an external object, such as an occlusion in a body lumen.

Abstract: A wire guide grabbing mechanism includes an elongate mandrel having a proximal and distal mandrel end, and a grabber irreversibly attached to the mandrel. The grabber includes a plurality of struts arranged in a reticulated pattern and a plurality of openings defined by the plurality of struts. The grabber is adjustable between an expanded configuration at which the plurality of struts are spread out relative to one another and a contracted configuration at which the plurality of struts are condensed, such that a wire guide may be enmeshed by the grabber in the contracted configuration. Related methodology is also disclosed.

Abstract: The present invention generally relates to a medical surgical device and specifically a wire guide for percutaneous placement within a body lumen. The wire guide includes an elongated mandrel having sufficient flexibility and kink resistance and a cannula having a stiffness greater than the mandrel stiffness for sufficient pushability. The mandrel extends through the cannula and has a portion extending distal thereto to form a distal tip of the wire guide. The wire guide can further include a slotted cannula to improve the flexibility of the wire guide at the proximal portion of the wire guide. The slots can be arranged in various patterns for increased flexibility along the longitudinal length of the cannula, as well as increased circumferential flexibility along the wire guide. The mandrel may also have a proximally tapered portion to improve the flexibility of the wire guide at the proximal portion of the wire guide.

Abstract: A torque-limiting clutch brake is provided that has an inner collar which splines to a transmission gearbox input shaft. An intermediate coupling member fits around and engages the inner collar. A friction generating resilient wave washer is disposed between the intermediate coupling member and an outer housing. The outer housing includes two covers, within which the components are contained and the resilient wave washer is partially compressed. Friction generated by the resilient wave washer conditionally couples the outer housing to the intermediate coupling member and inner collar until torque on the device exceeds a certain threshold, at which point the clutch brake slips to prevent damage. The components are made up of separable semicircular sections which can be split apart to facilitate removal and installation of the clutch brake without lowering and disassembling the vehicle transmission.

Abstract: A sheet separating machine automatically separates and removes a sheet of a dry nonextendable film from a printed circuit panel. The machine comprises a plurality of feeding rollers carrying the panel with the films attached to either or both sides thereof through the machine. The stop lever interrupts a movement of the panel at a predetermined location for a selected time interval. An edge separator for loosening a film edge during the interval rides along the film edge and separates the film edge from the panel by utilizing pressure wheels and turbulent air flow. Knife means breaking a bondage between the panel and the film force the film to completely separate from the underlying panel. The separated film is conveyed by the guide means toward a film accumulator.

Abstract: A stacker-loader is positioned at the end of a conveyor line for receiving printed circuit boards as they follow each other in series or sequence along the conveyor. The stacker-loader converts the series of boards into a stack of boards, one aligned over the other on a cart which may be removed. The boards are so stacked without any one sliding over another, since the conductive strip lines on confronting boards might catch on each other. The stacker-loader comprises a field of driven rollers for the enabling of the boards to sequentially travel in series one after another when they leave the conveyor. A pair of spaced parallel cantilever arms are positioned to receive, between themselves, each of the printed circuit boards as it is delivered from the field of driven rollers. An aligned plurality of wheels are mounted on and extended from confronting surfaces of the cantilever arms for supporting the boards as they move along the arms.
