Abstract: Systems and methods can involve wedge dissectors attached to strips in turn attached to medical balloons, for forming serrations within vascular wall tissue for angioplasty as well as drug delivery.

Abstract: There is disclosed a porous emboli deflector for preventing cerebral emboli while maintaining cerebral blood flow during an endovascular or open surgical procedure. The device prevents the entrance of emboli of a size able to cause stroke (such as greater than 100 microns) from entering either the right or left common carotid arteries, and/or the right or left vertebral arteries by deflecting emboli downstream of these vessels. The device can be placed prior to any manipulation of the heart or aorta allowing maximal protection of the brain during the index procedure. The deflector has a low profile within the aorta which allows sheaths, catheters, or wires used in the index procedure to pass. The deflector shaft could have a first portion and a second portion, the second portion being more flexible than the first portion. The deflector frame can include one, two, or more movable structures, such as hinges. Also disclosed are methods for insertion and removal of the deflector.

Abstract: A bite-block for protecting the mouth of a patient receiving electroconvulsive therapy includes a U-shaped frame made from a unitary piece of a flexible material, such as expanded polyethylene foam, having a first side and an opposite second side. The U-shaped frame includes a body portion and two spaced-apart lobes extending therefrom. The two lobes define a gap therebetween. A force absorbing pad extends upwardly from the first side along at least a portion of each of the two lobes. A handle portion may be added so that the frame is Y-shaped.
