Abstract: A system for traversing an arterial occlusion in an artery includes a housing sized to fit in a palm of a user, an elongate drive tube configured to be rotated by the housing, the drive tube including an axially extending passage, a cylindrical member, configured to be rotationally coupled to the drive tube, such that a distal tip of the cylindrical member may be delivered to a location adjacent the arterial occlusion when the cylindrical member is coupled to the drive tube, and wherein grasping and activating the housing such that the drive tube is rotated, thereby causes the distal tip of the cylindrical member to be rotated, the rotation of the distal tip including at least a component of linear oscillation.

Abstract: One preferred embodiment includes a guidewire manipulation device for manipulating a guidewire during a procedure. Preferably, the guidewire manipulation device includes a powered motor that drives a tandem roller assembly. The guidewire is passed through a hole positioned lengthwise through the device where the roller assembly engages the guidewire's outer surface. The interface of the manipulation device includes a power button that directs the internal roller assembly to roll the guidewire in a desired rotational direction. Additional interface controls are also preferable to provide a different roll patterns, depending upon surgeon preference and guidewire placement efficiency.

Abstract: A tool for neurological and diagnostic testing comprises the combination of a stethoscope with a reflex hammer including a light. When mounted on the stethoscope head the reflex hammer extends beyond the head, without interfering with the normal use of the stethoscope. A handle, which may or may not be joined to the reflex hammer, is positioned on the flexible stethoscope tubing and provides a gripping surface for using the tool for neurological testing. One embodiment includes a light within the reflex hammer, so that a light is available for testing responses to light at the same time as checking other responses. The reflex hammer and light combination is adaptable for use with binaural and electronic stethoscopes, thus providing a convenient set of instruments within a single device. A detent on the handle provides an ergonomic grip, or a place for inclusion of indicia.
