20090076518 | METHOD AND SYSTEM FOR STABILIZING ADJACENT VERTEBRAE - A method of stabilizing adjacent vertebrae including the steps of forming at least one annulotomy in an annulus. At least a portion of the nucleus material is removed through the annulotomy to form a cavity in an intervertebral disc space between the adjacent vertebrae. A reservoir containing a flowable biomaterial is fluidly coupled to the intervertebral disc space. A flowable biomaterial is delivered to the cavity. The delivery of the flowable biomaterial into the intervertebral disc space is controlled in accordance with at least a first operating parameter. The biomaterial is at least partially cured to stabilize the adjacent vertebrae. | 03-19-2009 |
20090078255 | Methods for pressure regulation in positive pressure respiratory therapy - Methods of positive pressure therapy are described. The methods increase the pressure delivered to a user from a sub-therapeutic pressure to a therapeutic pressure in one or more pressure steps sequenced to the user's breath intervals. | 03-26-2009 |
20090078258 | Pressure regulation methods for positive pressure respiratory therapy - Methods that may provide a positive pressure therapy to a user are described. The methods include detecting the user's breathing parameters and increasing the pressure delivered to the user from a sub-therapeutic pressure to a therapeutic pressure based upon the breathing parameters. | 03-26-2009 |
20100065054 | METHODS FOR BATTERY POWER MANAGEMENT OF POSITIVE AIRWAY PRESSURE APPARATUS - Methods relating to the power management of positive airway pressure apparatus using a battery are disclosed herein. The methods, in various aspects, are adapted to prolong the delivery of a positive airway pressurized therapy when the positive airway pressure apparatus is operated under battery power. | 03-18-2010 |
20120097156 | POSITIVE AIRWAY PRESSURE THERAPY MASK HUMIDIFICATION SYSTEMS AND METHODS - The present inventions provide positive airway pressure therapy apparatus to humidify the pressurized air delivered to a user during various positive airway pressure therapies and corresponding methods. The positive airway pressure therapy apparatus may be configured to administer one or more positive airway pressure therapies, including: continuous positive airway pressure therapy (CPAP), bi-level positive airway pressure therapy (BPAP), auto positive airway pressure therapy (autoPAP), proportional positive airway pressure therapy (PPAP), and/or other positive airway pressure therapies. | 04-26-2012 |
20120167879 | POSITIVE AIRWAY PRESSURE THERAPY APPARATUS AND METHODS - Embodiments of the invention are directed to positive airway pressure therapy apparatus and methods for using same. In some embodiments, the apparatus includes a body- (e.g., head-) mounted housing enclosing a blower, wherein the housing includes air inlets on multiple sides so that the blower may draw adequate air even when inlets on one side are obstructed. In another embodiment, the apparatus includes a mask or mask system securable to an airway of the user. The mask system may include a mask shell and two or more adapters configured to permit the attachment of two or more different mask seals to the same mask shell. Other embodiments of the invention describe strapping systems configured to removably attach the housing and the mask to the body. The apparatus may further include a drying mode that activates upon removal of the apparatus from the user. | 07-05-2012 |
20130098359 | NARES MASK AND SUPPORT APPARATUS - Embodiments of the present invention provide a nares mask and support apparatus (e.g., for use with a positive airway pressure therapy system) that may generate the desired mask retaining force while reducing or even eliminating the need for supplemental facial contact elements such as face-contacting straps or bands. The apparatus may include a first biasing element that biases a nares interface in a direction generally orthogonal to and towards the user's face. A second biasing element may bias the nares interface in a direction generally parallel to the face and towards the user's forehead. The biasing forces applied by the first and second biasing elements may thus produce a resultant force that biases the nares interface in a direction generally aligned with an axis of the nares. | 04-25-2013 |

20140330156 | APPARATUS AND METHOD FOR ADAPTING A PIEZOELECTRIC RESPIRATORY SENSING BELT TO A RESPIRATORY INDUCTANCE PLETHYSMOGRAPHY POLYSOMNOGRAPH - Circuits for rendering piezo-based respiratory belts compatible with polysomnograph (PSG) machines designed for use with respiratory induction belts (RIPs) comprise an instrumentation amplifier adapted to be connected to a piezoelectric transducer and providing an AC output signal to a low-pass filter. In a first embodiment, the low-pass filter output is applied to an input of a microcontroller's A to D converter and the resulting digitized samples are used to vary the resistance of a digital potentiometer whose wiper terminal is coupled in series with an inductor so as to emulate the presence of a RIP belt to the PSG machine. In a second embodiment, the low-pass filter output is used to drive the primary of a transformer so as to vary the permeability of the transformer's ferrite core in a way that emulates the performance of a RIP belt to the PSG. | 11-06-2014 |
