Abstract: A cover for a urinary catheter may include a cover sheath, the cover sheath including a longitudinal slit extending from a first end of the sheath to a second end of the sheath. The catheter cover may also include and a spring mechanically coupled to the cover sheath and configured to retain the slit in a closed state, where the cover sheath substantially surrounds an outer diameter surface of the urinary catheter when the cover sheath is in the closed state.

Abstract: A stethoscope cleaning device may include one or more of the following features: a first portion configured for supporting a stethoscope, wherein the first portion includes an earpiece chamber for receiving an earpiece of the stethoscope; and a second portion configured for receiving a container. The first portion may be movable (e.g., pivotable) relative to the second portion, and movement of the first portion relative to the second portion may cause a cleaning fluid to flow from the container to the earpiece chamber.

Abstract: A brush for non-invasive biopsy may include a distal tip forming a cavity, where an opening of the cavity faces proximally. A shaft may be included, where the shaft is movable relative to the distal tip, where a distal end of the shaft is located within the cavity when the brush is in a first state, and where at least a portion of the distal end of the shaft is located outside the cavity when the brush is in a second state. A set of bristles may be located at the distal end of the shaft, where the bristles at least partially move from within the cavity of the distal tip to outside the cavity of the distal tip when the brush moves from the first state to the second state.

Abstract: An affixation device for a human skull may include a base plate that has an outer area for securing to the skull and an inner area for securing to a bone flap removed from the skull. The affixation device may also have at least one spacer located between the outer area and the inner area, where the at least one spacer extends from a first surface of the base plate, where the first surface facing the skull when the fixation device is in an installed state, and where the at least one spacer is configured to extend between the bone flap and the skull in the installed state.

A shaft may be included, where the shaft is movable relative to the distal tip, where a distal end of the shaft is located within the cavity when the brush is in a first state, and where at least a portion of the distal end of the shaft is located outside the cavity when the brush is in a second state. A set of bristles may be located at the distal end of the shaft, where the bristles at least partially move from within the cavity of the distal tip to outside the cavity of the distal tip when the brush moves from the first state to the second state.

Abstract: A catheter may include an elongated tube enclosing at least one catheter lumen, and a centering device coupled to a distal end of the elongated tube, wherein the centering device includes a plurality of legs. Each leg of the plurality of legs may include a first end fixed to an outer surface of the elongated tube. Each leg of the plurality of legs may include an outward bias such that a central portion of each leg of the plurality of legs is spaced radially outward from the elongated tube when the centering device is in an expanded state.

Abstract: A vacuum pad may include a top layer forming a top surface of the vacuum pad; a bottom layer forming a bottom surface of the vacuum pad; and a plurality of spacers located between the top layer and the bottom layer such that an interior space is formed between the top layer and the bottom layer. The interior space may have at least one channel extending around at least one spacer of the plurality of spacers. The vacuum pad may also include an outlet tube in fluid communication with the interior space, where the top layer includes a plurality of holes. A vacuum system may include the vacuum pad along with a canister and a vacuum source for moving fluid from the vacuum pad to the canister.

A shaft may be included, where the shaft is movable relative to the distal tip, where a distal end of the shaft is located within the cavity when the brush is in a first state, and where at least a portion of the distal end of the shaft is located outside the cavity when the brush is in a second state. A set of bristles may be located at the distal end of the shaft, where the bristles at least partially move from within the cavity of the distal tip to outside the cavity of the distal tip when the brush moves from the first state to the second state.

Abstract: The present invention relates to methods of diagnosing traumatic brain injury (TBI) in a subject. The present invention also relates to methods of monitoring the progression of the TBI in a subject.

Abstract: A wound irrigation device may include a barrel having a fluid chamber at least partially filled with an irrigation fluid. A piston may be located in the barrel, where the piston is movable between a terminal proximal position and a terminal distal position within the barrel to control a volume of the fluid chamber of the barrel. An actuation spring may be mechanically coupled to the piston, where the actuation spring is configured such that a pressure of the irrigation fluid within the fluid chamber continuously exceeds about 4 psi as the piston moves between the terminal proximal position and the terminal distal position.
