摘要:
Embodiments of the invention provide methods of obtaining continuous cardiac information from a mammal. First, attach a self-contained, wearable, portable continuous cardiac monitor to the mammal to create a chamber containing electrodes used to detect cardiac signals from the mammal. Next, continuously detect without analyzing the cardiac signals from the mammal for at least 24 hours. Next, store information related to substantially all detected cardiac signals in the cardiac monitor.

One embodiment of the invention is a cardiac monitor having a housing; a plurality of electrodes within and extending from the housing; a state machine within the housing configured to digitialize and store in memory signals from the plurality of electrodes; a sealing surface and an adhesive on the sealing surface configured to form a watertight perimeter around the plurality of electrodes when the housing is affixed to a mammal. Another embodiment of the invention provides a continuous cardiac monitor having a housing; a surface on the housing adapted to be sealably engaged to a mammal; an adhesive on the surface that is adapted to remain affixed to the mammal for at least 7 days; at least two electrodes within the housing positioned to detect a cardiac information of the mammal while the surface is sealably engaged to the mammal; an electronic memory within the housing wherein, the electronic memory is sized to store at least 24 hours of continuous cardiac information; and wiring within the housing connecting the electronic memory to the electrodes.
摘要:
Continuous single-step processes for producing higher molecular weight ketones are disclosed that involve a liquid-phase crossed condensation of an aldehyde with a ketone in the presence of a hydrogenation catalyst and a small amount of a catalyst comprising a concentrated hydroxide or alkoxide of an alkali-metal (from Group 1 or Group IA of the Periodic Table of the Elements) or alkali-earth metal (from Group 2, or Group IIA of the Periodic Table of the Elements), wherein the amount of water provided to the reaction mixture, or reaction zone, is relatively low, with respect to the total initial weight of the reaction mixture. The reaction may be carried out in the absence of solubilizing agents or phase transfer agents. The product mixture is largely free of by-products resulting from further condensation reactions of the desired ketone product or intermediates, and free of the self-condensation products of the reactant aldehyde, that are afterward difficult to remove from the reaction mixture.

The subject invention concerns vascular prosthetic devices and methods for ascending aorta and/or valve replacement in humans and animals. In one embodiment, a device of the invention includes a vessel-like structure having a first end adapted for surgical attachment to a left ventricle, a second end adapted for surgical attachment to an aorta, and, interposed between the first and second ends, a sinus portion configured in the shape of the sinuses of Valsalva in a human aortic valve.
摘要:
A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen having a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end and a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen. The device body is adapted and configured to move from a position where the device lumen blocks flow through the bodily lumen to a position where the device lumen allows flow through the bodily lumen. In other configurations, there are one or more valves within the device lumen adapted and configured to move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen. There is also a method for implanting a device within a body lumen by placing a device having a device body and fixation elements extending from the device body on a catheter and then dilating the body lumen such that the device body and the fixation elements may advance through the dilated body lumen without the fixation elements engaging the wall of the body lumen. Next, advancing the device to an implant site within the body lumen and then engaging the walls of the body lumen with the fixation elements.

Embodiments of the present invention provide a method of analyzing cardiac information by collecting a plurality of self-contained, wearable, portable cardiac monitors each of the cardiac monitors electronically storing at least 24 hours of continuously detected and unanalyzed cardiac signals from a mammal. Next, retrieving cardiac information stored in each of the plurality of self-contained portable cardiac monitors. Next, forwarding retrieved cardiac information.
