US Classification:

600490, 600494, 600495, 600493

Abstract:

An oscillometric, noninvasive blood pressure monitor comprising an inflatable cuff adapted for placement around a body member, a pump for cuff inflation, a pressure transducer connected to the cuff, means for detecting oscillations in arterial pressure occurring during a transition in cuff pressure between a pressure greater than normal systolic pressure and a pressure less than normal diastolic pressure, and a blood pressure measurement circuit which is capable of determining the maximum amplitude (A) of the oscillations, identifying mean cuff pressure (P) as the coincident value of the cuff-pressure signal from the pressure transducer, and determining systolic pressure as a function of both Aand P. In accordance with one aspect of the invention, the blood pressure monitor has an optical sensor including a light source and photodetector optically coupled to the body member proximate to the cuff. Oscillations in the output signal of the photodetector are detected, and the blood pressure measurement circuit determines the oscillation amplitude corresponding to systolic pressure (A) as a function of both Aand P.

US Classification:

600324, 600344, 600499

Abstract:

An optical noninvasive vital sign monitor comprising a reflectance-type optical sensor within a pressurizable capsule retained by a headband, the capsule having an optically transparent or translucent inner wall adapted for placement against a subject's forehead. The optical sensor is mounted on the inside surface of the pressurizable capsule's inner wall, which contacts the subject's forehead during use, and includes a light source and a photodetector aimed toward the inside surface of the inner capsule wall. One embodiment of the vital sign monitor includes optical oscillometric circuit means responsive to an output signal from the optical sensor for determining systolic pressure, mean pressure and diastolic pressure during a transition in capsule pressure between a pressure greater than normal systolic pressure and a pressure less than normal diastolic pressure.

International Classification:

A61B 5/00

US Classification:

600485, 600500

Abstract:

An auditory pulse monitor for noninvasively detecting the amplitude of arterial pulses on a beat-by-beat basis. A light-weight optical sensor including a light source and photodetector is adapted for application to the skin surface of a subject over a tissue bed containing an arterial supply. The photodetector generates an output signal proportional to the amplitude of an arterial pulse, and an electronic circuit connected to the photodetector generates a signal having a frequency proportional to the photodetector output signal level. A speaker or other audio indicator connected to the electronic circuit generates an audible tone indicating the amplitude of the arterial pulse. Another aspect of the invention is an improvement in automated or automatic external defibrillators (AEDs). An AED is disclosed which optically detects arterial pulses after delivering a defibrillation shock and signals the need for CPR if it detects inadequate cardiac pumping following successful defibrillation.

International Classification:

US Classification:

623 124

Abstract:

A method for preparing vascular valves from submucosal tissue is described. Both bicuspid and tricuspid valve constructs are described. The bicuspid constructs can be formed with or without a supporting stent. The tricuspid constructs are formed by fixing submucosal tissue to a supporting stent, folding the submucosal tissue, and forming the valve commissures from the folded submucosal tissue by cutting along the folds. The artificial vascular valves are useful for replacing damaged or diseased valves of a warm-blooded vertebrate.

International Classification:

A61B 18/14

Abstract:

Tissue cutting systems and methods of tissue cutting are provided. In one example, the tissue cutting system includes a first device and a second device adapted for coupling to a power supply. The first device includes a conductive probe. The second device includes a conductive material, for example, as part of an expandable structure, having an outer surface area of conductive material that may be larger than a surface area of the conductive probe. The conductive probe and the conductive material are deployed along opposite sides of a body tissue, such as an aortic dissection flap. Selective electrical power is applied to the conductive probe and the conductive material to cut the body tissue.

Abstract:

A method of treating a vessel, such as sclerotherapy, includes moving a short balloon catheter to a position at which a compliant extra-luminal balloon is outside of the vessel at an occlusion site, and between the vessel and a non-compliant bearing surface. The vessel is occluded at the occlusion site by inflating the compliant extra-luminal balloon of the balloon catheter, and bearing an outer surface of the balloon against the vessel and the non-compliant bearing surface. The vessel is medically treated upstream from the occlusion site. The short balloon catheter includes a wire guide lumen
