Abstract: A method comprises advancing a medical instrument toward a target within a patient anatomy, and the medical instrument includes a marker. The method further comprises depositing the marker at a location at or near the target along a trajectory of the medical instrument. The method further comprises sensing the marker to indicate a location of the target. The method further comprises, based on the marker, determining a second trajectory along which a treatment instrument may be advanced toward the target to treat the target. The second trajectory is different than the trajectory.

Abstract: A method comprises advancing a medical instrument and a catheter toward a target tissue within a patient anatomy. The instrument includes a distal sheath marker and is slidably received within the catheter. The distal sheath marker includes a channel and an identification feature. A portion of the instrument is slidably received within the channel. The method further comprises depositing the distal sheath marker at a location at or near the target. The distal sheath marker indicates a farthest advancement point of the instrument within the patient anatomy. The method further comprises: after depositing the distal sheath marker, withdrawing the instrument away from the target; determining an orientation of the distal sheath marker based on the identification feature; and, after withdrawing the instrument, using the location and orientation of the deposited distal sheath marker to determine a trajectory of a distal end of the instrument at or near the target.

Abstract: An illuminated display mirror includes a frame having panel receiving area defined by a front retaining portion and a side retaining portion extending rearwardly from the front retaining portion, a transparent panel to be held within said panel receiving area and having a highly reflective coating at least partially on a surface thereof and at least part of the surface free of any reflective coating and defining an image receiving area, and having a registration indicia, a light transmissive substrate having a printed image thereon and having a corresponding registration indicia formed thereon for registering the printed image in the image receiving area and a light emitting member.

Abstract: A medical tracking system comprises a fiducial apparatus that includes a sensor docking feature configured to mate with a mating portion of a sensor device. The sensor docking feature retains the mating portion in a known configuration. The fiducial apparatus also includes at least one imageable fiducial marker and a surface configured for attachment to an anatomy of a patient.

Abstract: A vinyl graphic decal includes a vinyl member having a first side with an adhesive material applied thereto and a second side including an image printed thereon which imparts a theme having an aesthetically oriented sweet spot and a peripheral portion having an inner portion and an outer portion which lends itself to removal of the other portion without deleteriously affecting the theme of the image. The peripheral portion includes predefined lines of demarcation which provide a guide for removal of one of the portions of the peripheral portion in a manner to maintain the aesthetically orientation of the sweet spot relative to a remaining portion of the peripheral portions.

Abstract: A system and method are disclosed after chemical processing involving agitation and/or mixing of components. In one embodiment, the chemical processing involves pressure oxidation and in another embodiment involves pressure leaching. Agitation during chemical processing is aided by an agitator pump disposed in each compartment or stage of a reactor to draw components into a cavity of the agitator pump. In another embodiment, feed to a multi-stage reactor is split between different compartments of reactor.

Abstract: A system and method for recovering gold using pressure oxidation is disclosed. In one embodiment, a feed slurry is introduced into multiple compartments or stages of a multi-stage autoclave. In another embodiment, an agitator pump is disposed in each compartment or stage of an autoclave to draw the feed slurry and oxygen into a pump cavity for intimate mixing. Preferably these embodiments are used in combination, and each is believed to contribute to enhanced utilization of the oxygen within the autoclave.

Abstract: Apparatus for releasably locking a tilt steering wheel assembly in adjusted position comprises a bracket having a pair of spaced-apart plates affixed to the jacket of the steering shaft, and a pawl between the plates pivoted to the steering wheel assembly. Each plate has a hole and the holes are aligned. The pawl has a series of spaced holes. The pawl has a cam track. A cam on the bracket is engageable with the cam track to cause the pawl holes to align successively with the bracket holes when the steering wheel assembly is pivoted to various different positions. A lock pin is engageable in the aligned bracket and pawl holes to lock the steering wheel assembly in a desired position of adjustment.
