Abstract: Apparatus and method are for extraction of follicular units. A dermal biopsy punch is utilized in combination with a suction device for extraction purposes. The use of suction to extract the follicular unit allows for distribution of the forces over a large area of the unit, helping to keep the unit intact. A perforating device, affixed to the punch, is utilized to weaken the structural integrity of the extraction area. The perforating device, having a single spike member which is inserted into the skin at a small, previously determined depth, in several locations, surrounding the follicular unit and reducing the holding tissue around the unit. The spike member of the perforating device is relatively thin and unlikely to damage the follicular unit. Because suction is utilized to extract the follicular unit, the distal end of the apparatus may have a guard which functions to prevent the extracted follicular units from being vacuumed further therein.

Abstract: Disclosed is an apparatus and method for uniform selective cerebral hypothermia. The apparatus includes a brain-cooling probe, a head-cooling cap, a body-heating device and a control console. The brain-cooling probe cools the cerebrospinal fluid within one or more brain ventricles.

Abstract: Adapting crosslinking with triglycidyl amine (TGA) to incorporate the use of a particular type of anti-calcification agent provides a broad-reaching solution to the problem in vivo bioprosthesis calcification. The anti-calcification agent in question includes a polyphosphonate compound that contains a functional group, which serves as a reaction site between the polyphosphonate and a polyepoxide. The functional group is reactive enough to dominate the reaction between the polyphosphonate and the polyepoxide, thereby excluding the chelating oxygen atoms of polyphosphonate from the reaction, protecting their anti-calcification ability. Furthermore, the high reactivity of the functional group allows the polyphosphonate to attach to the polyepoxide more completely, which improves the calcification resistance of bioprosthetic material with which the polyepoxide is crosslinked.

At an inlet into the gas separation apparatus, a water spray is introduced into the gas stream. The water spray may include various chemical additives, typically selected to react with or neutralize the particulates as they are mixed with the water or for other benefit.

The electric field is generated between the cylinder wall and the central electrode, to assist the centrifugal forces and thereby remove additional particulate beyond that ordinarily removed by a standard centrifugal separator.
