Abstract: A manually operable pointing device for use with a computer, adapted for use with a prosthetic hook, includes a shell, a bearing surface, a receptacle, and first and second actuating levers. The shell has a first end and a second end positioned distal thereto. The bearing surface is positioned at the first end of the shell for supporting a portion of the hook. The receptacle is positioned proximate to the second end of the shell and is adapted to receive a tip of the hook. The first actuating lever extends from the first end to the second end and is movable relative to the shell. The second actuating lever extends from the first end to the second end, is movable relative to the shell, and positioned adjacent to the first actuating lever.

Abstract: A catheter assembly uses articulating wires which extend from a traction mechanism mounted on a control handle to a distal end of the catheter to steer the catheter as it traverses internal cavities of a patient. A camera and a light may be mounted on the catheter for use with an imaging monitor for visual guidance of the catheter. A luer fitting and a valve mounted on the control handle are used to control the flow of fluid into and out of the catheter lumen.

Abstract: The invention includes methods and apparatuses for patient transfer from a rollable chair to a bed and back. A rollable chair includes a first frame having a seat; a second frame coupled to the first frame, the second frame having a backrest configured to move relative to the first frame; and a third frame coupled to the first frame, the third frame having a track having a curvilinear length configured to allow the first frame to rotate and to translate relative to the third frame. A bed includes a chair-receiving frame configured to couple to the first frame of the rollable chair. The rollable chair and the bed work in tandem to transfer a patient, for example using coordinated, automated motions.
