Abstract: A miniaturized cardiopulmonary bypass circuit for a mouse comprises at least one venous catheter connected to a patient, a dual channel peristaltic pump having one channel to move the blood by tubing from the patient, an oxygenator that removes gases from the blood and mixes the blood with fresh gases to oxygenate the blood, the blood being moved from the oxygenator to the arterial catheter by the dual channel peristaltic pump, and an arterial catheter. The blood is pumped by a two-channel roller pump into an inlet nozzle, where the flow of blood is transformed from tubular flow to planar flow. Gas exchange occurs inside the case while the blood flows down the central component. Blood then flows down the central component into the arterial reservoir. The arterial reservoir is connected to the second channel of the pump, and returned to the patient through a cannula.

Abstract: Wrist, hand, or arm support devices are provided. The support devices include a support member having a top surface and a front surface. The top surface is oriented at either a parallel angle or a non-parallel angle with respect to a work surface. The front surface curves upon itself to form either a symmetric or an asymmetric arc. Preferred versions of the support devices described herein include at least one of a top surface oriented at a non-parallel angle with respect to the work surface or a front surface that curves upon itself to define an asymmetric arc. Mounting members for connecting the support member to an operating surface are also provided. The support devices described herein permit an operator to comfortably rest his or her hand on the support devices while directing procedures toward non-centered portions of work objects.

Abstract: A sandal comprises a sole, a first strap having a first end, a second end and at least one first magnetic member positioned between the first and second ends, each of the first and second ends mounted to the sole at a predetermined position such that the first strap and the sole define an opening for receiving a foot of a user and retaining the foot therein, and a second strap having a first end, a second end and at least second magnetic member positioned between the first and second ends corresponding to the at least one first magnetic member of the first strap such that the second strap is releasably attachable to the first strip by a magnetic attraction force generated between the at least one first magnetic member of the first strap and the corresponding at least one second magnetic member of the second strap.
