Abstract: The present disclosure is directed to a system for treating a blood vessel including a blood vessel lumen defined by a blood vessel wall, the blood vessel lumen being at least partially obstructed. The system may include a shaft assembly including an orienting element. The system may also include a re-entry device extending into the central lumen. The re-entry device may comprise a core wire configured such that bending stresses created in the core wire during bending about a design bend radius are less than the elastic limit of the core wire so that the core wire will elastically recover from the bending upon release.

Abstract: A force sensor, for use in combination with an automated electronic defibrillator (AED), includes a first conductive layer. A second conductive layer is spaced apart from the first conductive layer such that no electrical communication occurs between the first and second conductive layers. An electrical communication device is provided for establishing electrical communication between the first and second conductive layers responsive to the application of a force to said electrical communication means.

Abstract: An electrode system includes a release liner separating a pair of electrodes. The release liner includes a first portion having electrically conductive and non-stick characteristics and a second portion having electrically non-conductive and non-stick characteristics. An electrically conductive portion of the electrode is disposed over the first portion while an adhesive only, electrically non-conductive portion of the electrode is disposed over the second portion. The release liner includes a pair of electrically non-conductive sheets and an electrically conductive sheet interposed between the non-conductive sheets. The non-conductive sheets include an aperture to expose a portion of the conductive sheet for providing electrical conductivity between the pair of electrodes.

Abstract: A facial mask for use in medical respiratory treatments such as sleep apnea CPAP therapy. The mask includes a preferably transparent front plate to which is attached a skirt of flexible material adapted to sealingly impinge on the face of a patient. The mask is of sufficient size so that as it seals the nose from all but the desired therapeutic airflow, the sealing pressures will be felt on the forehead, the upper lip, and the malar region of the face spaced from the nose. Thus pressure on the bridge of the nose and in the maxillary region adjacent to the nose are avoided, resulting in a significant decrease in the possibility of intense pain.

Abstract: A heat exchanger bed including a plurality of elastomeric sheets. The sheets have a peripheral edge and a center. The sheets also have an opening therethrough proximate the center. The sheets are stacked one next to another in a stack. At least one sheet spacer is disposed between adjacent sheets of the stack. The center openings of adjacent sheets are aligned to define a passage through the stack.

Abstract: A heat exchanger medium which can be incorporated into a heat and moisture exchanger. The heat exchanger medium includes an elongate sheet of spunbonded olefin. The sheet has a longitudinal axis, a front and back surface and first and second edges generally parallel to the longitudinal axis of the sheet. The sheet may be covered with a hydrophilic coating and a desiccant.

Abstract: An apparatus and method for electrically stable electrodes and sensors having a flexible base or substrate. One or more flexible and pressure sensitive resistors having a high resistance and a high temperature coefficient of resistivity are printed on a first surface of the flexible base, and a second set of one or more substantially identical resistors are printed on a second surface such that each resistor on the second surface is directly opposite a resistor on the first surface. The opposing resistors are then electrically interconnected in mating pairs, so that when the substrate is flexed, one resistor of each pair is compressed and the other is tensed with the result that the changes in resistance cancel one another.
