Abstract: A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically pauses thermal treatment of the patient prior the patient reaching a target temperature. During the pause, the controller assesses a reaction of the patient and changes a temperature of the fluid only inside the thermal control unit if the patient is likely to reach the target temperature without further thermal treatment. However, if the patient is unlikely to reach the target temperature without further thermal treatment, the controller restarts the thermal treatment. The controller may pause thermal treatment again prior to reaching the target temperature and assess the patient's reaction. In some embodiments, the controller may selectively include and exclude a fluid reservoir in a circulation channel within the thermal control unit.

A balloon member is secured to an outer surface of a distal portion of the catheter such that an inner surface of the balloon member and an outer surface of the catheter define an inflatable balloon interior. The catheter has an inflation lumen connected to an inflation port and extending distally to a distal end in fluid communication with the inflatable balloon interior. One or more purge apertures are provided in a wall of the catheter, each forming a fluid path between the inflatable balloon interior and the inner lumen of the catheter to allow for purging air from the catheter prior to use in a medical procedure.

The transducer assembly includes a gear coupled to the probe and at least two rotational sensor devices coupled to the gear to determine an amount of movement of a probe relative to a housing to determine a bore depth of the hole. The gear has a reference point having an angular path of rotation about a gear axis subdivided into separate first and second arcuate regions. A first sensor device is configured to detect a rotational position of the reference point in the first arcuate region, and a second sensor device is configured to detect a rotational position of the reference point in at least the second arcuate region, with the first sensor device incapable of detecting the reference point in the second arcuate region.

Abstract: A patient handling apparatus includes a patient support surface, a base, and a hydraulic circuit. The hydraulic circuit includes a pump, a fluid reservoir, and a hydraulic cylinder operable to selectively raise or lower the patient support surface or the base. The hydraulic circuit controls flow of fluid between the cylinder and the fluid reservoir to thereby control the movement of the base or patient support surface. In addition, the hydraulic circuit may include a manual bypass circuit configured to bypass the pump in response to a manual input, which allows manual extension or retraction of the cylinder, for example, when the pump is not operational. The hydraulic circuit may also include a pump bypass circuit configured to bypass the pump to allow fluid to discharge from the cap end to the fluid reservoir for faster evacuation of fluid from the cylinder, thereby increasing retraction speed of the rod.

Abstract: A first light source with a first etendue generates a first light beam to travel along a first optical path having an expanded portion formed by a collector optical system. A second light source having a second etendue less than one tenth of the first etendue forms second light, which is conducted by a light guide having a distal section with an end face. The second light is emitted from the end face as a second light beam that travels over a second optical path that resides within the expanded portion of the first optical path due to the light guide being disposed relative to the first optical path from an off-axis direction. An optical condenser receives and directs the first and second light beams to a common exit plane to form the combined light beam.
