Abstract: A system for performing image-guided surgery includes an instrument having a first portion configured to define a trajectory into the body of a patient, a marker device and a user-interface component. A sensing device receives electromagnetic signals that are reflected or emitted from the marker device, and a processing system, coupled to the sensing device, includes at least one processor configured with processor-executable instructions to perform operations that include tracking the position and orientation of the instrument relative to the patient based on the signals received at the sensing device, receiving a signal from the user-interface component of the instrument indicating a user-input event, and saving the trajectory into the body of the patient defined by the first portion of the instrument in response to receiving the signal.

Abstract: The invention provides a multi-compartment container for storing and dispensing separately a plurality of consumable liquids that can be mixed in an accurate and repeatable manner. Each storage compartment within the container encloses a predetermined quantity of a consumable liquid, wherein the first compartment is filled with a first liquid and the other compartments are filled with second and third liquids. The individual storage compartments are structurally merged to form elongated dispensing compartments each with a first end and a second end, wherein a one-way outlet positioned at the first end and a one-way outlet located at the second end permits passage of liquid from the storage compartments into the corresponding dispensing compartments. Upon fully inverting the container, the designated outlet of each dispensing compartment is opened, wherein precise amounts of liquids in the first, second, and third compartments are dispensed at constant volume ratio using gravity.

Abstract: Conically-shaped earpieces with flexible covers for a stethoscope are described, which sit on the outside of the user's ears and are particularly useful for users with hearing aids. A stethoscope structure with conically-shaped earpieces is also disclosed. The stethoscope structure has a branched elongated tube, ear tubes, a connector, a chest piece, at least one conically-shaped earpiece, and flexible cover for each earpiece.

Abstract: A locking device useful for example for bicycles in which a pair of shackles is spaced apart and fittable into cross bars, each cross bar having a locking mechanism so that the locking device can be locked and opened at either end, that is, at either cross bar.

Abstract: A liquid dispenser for medical applications includes a pressurized liquid container, a nozzle, and a conduit or flow guide connected to the container and the nozzle for defining a flow path between the container and the nozzle. A manually actuatable flow rate control mechanism is operatively coupled to the conduit or flow guide and is manipulable by a user to adjust an average rate of flow of liquid from the container to the nozzle. In addition, a manually actuatable pulse rate control mechanism is operatively coupled to the conduit or flow guide and is manipulable by a user to adjust a rate of pulsation in liquid flowing from the container to the nozzle. The invention thus enables a user to set flow rate and pulsation frequency as desired.

Abstract: A liquid dispenser assembly for medical applications includes a container holding a predetermined quantity of a therapeutic liquid in a storage chamber. The container has a wall or panel provided with a port. A dip tube is disposed in the chamber and extends from the port to a lower portion of the storage chamber. The disepnser assembly further includes a hollow compressible dispenser body. An applicator tube is attached at one end to the dispenser body and extends at a free end, i.e., an end opposite the dispenser body, into the dip tube. The applicator tube is removable from the dip tube after an expansion of the dispenser body from a collapsed configuration and a concomitant drawing of an aliquot of the liquid into the dispenser body through the dip tube and the applicator tube.
