Patent number: 8956379Abstract: The present invention relates to devices and systems that alter intracranial compliance, cerebral blood flow and/or intracranial pressure pulsatility/waveform by oscillating the contraction and expansion of a compressible composition within the cranial or spinal cavities such that they increase intracranial capacity. The contraction and expansion of the compressible composition in the oscillating compliance devices can be due to an individual's intracranial pressure, the result of the expansion and compression of a reservoir which is mediated by the contractility of the heart or driven by a pump gaited to a biorhythm. The invention also relates to methods for protecting an individual's brain from abnormal arterial pulsations and for altering an individual's cerebral blood flow using the devices and systems of the invention.Type: GrantFiled: January 18, 2008Date of Patent: February 17, 2015Assignee: The Cleveland Clinic FoundationInventors: Mark G. Luciano, Stephen M. Dombrowski

Patent number: 8939928Abstract: Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.Type: GrantFiled: July 23, 2009Date of Patent: January 27, 2015Assignee: Becton, Dickinson and CompanyInventors: Richard Savoie, Gary Searle

Patent number: 8936720Abstract: The present system and method in one embodiment limit a maximum instantaneous peritoneal volume to a comfortable level, while allowing the dialysis machine to advance to fill a prescribed volume whenever the drain ends after a minimum drain percentage has been attained. If a low drain condition occurs, the nominal fill volume is lowered and a therapy cycle is added, so that a prescribed total amount of fresh therapy fluid is used during therapy, maximizing therapeutic benefit. An allowable residual volume at the end of an incomplete drain is increased, thereby lowering the probability of a subsequent low drain condition.Type: GrantFiled: August 1, 2011Date of Patent: January 20, 2015Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Robert W. Childers, Ying-Cheng Lo, Peter Hopping

Publication number: 20150018632Abstract: A system for measuring of cardiac blood flow balance parameter between the right chamber of the heart and the left chamber of the heart includes a sensor device for measuring one of blood pressure and blood flow rate and blood constituent concentration of a patient so as to generate an arterial pulse signal. A processing unit is responsive to the arterial pulse signal for generating a full arterial pulse signal, an arterio-venous pulse signal, and a balance parameter. A computational device is responsive to the balance parameter for further generating a set of physiological parameters. A display station device is responsive to the set of physiological parameters from the computational device for displaying meaningful information.Type: ApplicationFiled: July 15, 2013Publication date: January 15, 2015Inventor: Mohammad Khair

Publication number: 20150011976Abstract: An active agent or drug injecting device (10) includes a main housing (16) containing a trigger mechanism (24) which can be manually activated via release bar (32) or remotely triggered via wireless receiver (70) activating motor (74), and a second housing (80) containing an injection- and needle-assembly (22). The needle (30) encloses a dry carrier (26) having an active agent (12) disposed thereon. The trigger mechanism triggers the injection assembly to propel the needle into the skin (via spring (54)), to inject the active agent into a living organism (either by letting the active agent diffuse out of the needle or by actively flushing it out), and to subsequently retract the needle back into the housing (80) (via spring (64)).Type: ApplicationFiled: January 30, 2013Publication date: January 8, 2015Inventors: Lucien Vouillamoz, Melissa Rosen, Judy L. Walish, Daniel Yasevac, Michel Bruehwiler
