Circulatory assistance is provided in a non-invasive procedure safely and effectively using a microprocessor of an external counter pulsation device programmed to control the actuation of any or all of a plurality of valves, each of which is mounted on and in fluid communication with one of a plurality of individual inflatable bladders disposed in pockets within cuffs encasing the calves, thighs, buttocks, abdomen and/or chest of a person and an optional valve in fluid communication with the person's airway, in any desired sequence or order, toward the heart or toward the feet, either during diastole or systole, at desired inception times during the cardiac cycle, for selected durations and at chosen pressures, for treating a variety of cardiac, non-cardiac and circulatory conditions.

A method for treating patients suffering from left ventricular dysfunction, exhibited by a left ventricular ejection fraction (LVEF) less than normal, is disclosed. The method involves applying, during diastole, for a time period of about one hour, about five days each week for at least about seven weeks, an incrementally increasing therapeutic pressure to the patients' lower extremities, from the calves through the thighs and the buttocks. The hourly treatments are carried out at incrementally increasing peak diastolic/systolic pressure ratios (D/S Ratios) in the range of about 0.4:1 up to about 0.6:1 and thereafter at a D/S Ratio in the range of 0.5:1 to 1:1 for each consecutive hourly treatment, with the proviso that the average D/S Ratio over the entire treatment regimen does not exceed about 0.9:1.

摘要:
Process for producing circuitized greensheets including multi-layer ceramic sub-laminates and composites comprising thin ceramic greensheets carrying and thin, fine line patterned conductive metal layers. The invention comprises releasably-supporting the thin greensheets on a temporary carrier support having an ablatable release layer, preferably over a patterned conductive layer, and filling the vias with conductive metal paste, whereby the thin greensheets are supported against warpage and distortion. The supported greensheets are formed as single layers, pairs and stacks thereof, as desired, and thereafter separated from the temporary support for use.

An Internet-based system and method facilitates interactive placing and acceptance of patient referrals within a health care community. A referring health care provider accesses the proposed specialty clinic or other provider through the system, identifies the patient and pertinent medical conditions, and responds to interactive queries put by the system to qualify the patient and his or her medical condition for the referral. The system automatically accepts or rejects the referral, proposes prior tests or treatments for the patient before another referral attempt is made, or accepts the referral subject to tests being completed. Accepted referrals are then scheduled by staff depending on their urgency as indicated in the interactive querying system. Rules governing the interactive querying are set by physicians and managers of the community and can be changed as conditions warrant. Security of patient information in the system in accordance with federal HIPPA requirements is readily provided via passwords and user log-ins.
摘要:
An interface layer for separating first and second microelectronic ceramic substrates during firing includes a thermally degradable binder, preferably a polymer, that degrades at temperatures above room temperature and below a firing temperature for the microelectronic ceramic substrates, and a separating material, such as boron nitride or graphite. The method of making the interface layer includes mixing the binder, one or more solvents for the binder, a plasticizer and the separating material for a sufficient period of time to form a homogeneous mass, then casting the material in a thin sheet to form the interface layer.

A surgical sleeve which includes an array of spaced apart protuberances on an interior wall surface. The spaced protuberance reduce the surface contact between the sleeve and the tip and define a network of generally uniform channels through which fluid may flow, irrespective of pressure applied to the sleeve. As a result, the sleeve is able to provide fluid flow which is better able to remove heat from the tip and provide a more uniform irrigation of the eye.

Camber of ceramic substrates is prevented by placing a conformable load tile over substrates during sintering. The conformable load tile has an initial curvature that facilitates escape of substrate binder gases during a burn out cycle. Subsequently, the conformable load tile conforms to the substrates under the higher heat of sintering temperature to maintain flatness of the substrates. To prevent sticking of the conformable load tile to the substrates, the conformable load tile is provided with a nonstick surface.
摘要:
Process for producing multilayer ceramic substrates using greensheet technology and thin dielectric ceramic greensheets for miniaturization purposes. The process avoids the screening of the thin greensheets by forming self-supporting fusible particulate metal electrode layers, interposing them with the thin greensheets and sintering the assembly to form the multilayer substrates such as integrated capacitors.
摘要:
An apparatus in which a deformable or compressible intraocular lens can be received and staged for insertion into a patient's eye. The apparatus has an elongated compression chamber with proximal and distal ends and a longitudinal passageway, having an inner surface, extending between the ends. The portion of the passageway adjacent to the proximal end forms a loading area in which the passageway gradually decreases in size for causing an intraocular lens to be deformed or compressed as the lens is moved along the passageway. A staging area having a top and bottom passageway wall, communicates with the loading area with the passageway wall including alignment means for retaining the intraocular lens in a deformed or compressed condition. A portion of the passageway is sized to retain the intraocular lens in the deformed or compressed condition. A portion of the passageway defining the loading area comprises a surface which includes an opening and a slot or groove for permitting withdrawal of forceps used for pushing the intraocular lens through the loading area and into the staging area for deforming or compressing the lens.
