| 20080221635 | IMPLANTABLE CARDIAC RHYTHM MANAGEMENT SYSTEM HAVING MULTIPLE THERAPY MODALITIES - A cardiac rhythm management system for providing a plurality of therapy modalities. For example, the system may include a cardiac resynchronization therapy module for providing cardiac resynchronization therapy and a pacemaker module for providing bradycardia therapy, as well as a selector module coupled to the cardiac resynchronization therapy module and the bradycardia module. The selector module may select an operating mode from among a plurality of operating modes including the cardiac resynchronization therapy module and the pacemaker module. Various manual and automatic methods may be used to select the operating mode. In addition, a reversion management system may be included to assist the cardiac rhythm management system to recover in case of a disruption to the system. | 09-11-2008 |
| 20100023078 | Cardiac resynchronization therapy parameter optimization - Systems and methods involve determination of CRT parameters using a number of CRT optimization processes. Each CRT optimization process attempts to return recommended parameters. The CRT parameters are determined based on the recommended parameters returned by one or more of the CRT optimization processes. The CRT optimization processes may be sequentially implemented and the CRT parameters may be determined based on the recommended parameters returned by a first CRT optimization process to return recommended parameters. The CRT parameters may be determined based on a combination of the recommended parameters returned. The CRT optimization processes implemented may be selected from available CRT optimization processes based on patient conditions. | 01-28-2010 |

| 20080306568 | Identifying heart failure patients suitable for resynchronization therapy using QRS complex width from an intracardiac electrogram - Methods and systems are disclosed for determining whether a patient is a responder to cardiac resynchronization therapy. The beginning and ending of the intrinsic ventricular depolarization are determined through signals measured from one or more electrodes implanted in the patient's heart. An interval between the beginning and ending of the intrinsic ventricular depolarization is computed and is compared to a threshold. The threshold may be determined empirically. The pacing parameters of a heart stimulation device, such as a pacemaker, may then be configured, for example, by setting the paced atrio-ventricular delay based on whether the patient responds positively to cardiac resynchronization therapy. | 12-11-2008 |

| 20100330394 | CCP-CPP MAGNETORESISTIVE READER WITH HIGH GMR VALUE - A magnetoresistive device having a high giant magnetoresistance (GMR) value and a moderate low resistance area product (RA) includes a first magnetic layer, a second magnetic layer, and a current confined path (CCP) spacer layer positioned between the first magnetic layer and the second magnetic layer. The spacer layer includes copper current confined paths extending between the first magnetic layer and the second magnetic layer in a matrix of magnesium oxide. The spacer layer is formed by a mixture copper and magnesium oxide, which is heattreated to form the copper current confined paths within the magnesium oxide matrix. | 12-30-2010 |
| 20110006033 | Magnetic Device Definition with Uniform Biasing Control - A method of fabricating a magnetic device is described. A mask removing layer is formed on a layered sensing stack and a hard mask layer is formed on the mask removing layer. A first reactive ion etch is performed with a non-oxygen-based chemistry to define the hard mask layer using an imaged layer formed on the hard mask layer as a mask. A second reactive ion etch is performed with an oxygen-based chemistry to define the mask removing stop layer using the defined hard mask layer as a mask. A third reactive ion etch is performed to define the layered sensing stack using the hard mask layer as a mask. The third reactive ion etch includes an etching chemistry that performs at a lower etching rate on the hard mask layer than on the layered sensing stack. | 01-13-2011 |

| 20100018396 | Method of Using Adsorptive Filter Element - An adsorbent article having a base body or matrix onto which is applied an adsorptive coating. The body or matrix can be a honeycomb matrix or structure having a plurality of cells defining a plurality of passages extending through the body. The adsorptive coating comprises an adsorptive media, such as activated carbon or ion exchange resin, that is bound by a polymeric adhesive or resin. A reactant material is preferably included in the adsorptive coating. The adsorbent article has a minimal pressure loss therethrough. | 01-28-2010 |
| 20100176068 | Web Comprising Fine Fiber and Reactive, Adsorptive or Absorptive Particulate - The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid. | 07-15-2010 |

| 20090069883 | MEDICAL DEVICE WITH SPONGE COATING FOR CONTROLLED DRUG RELEASE - The medical devices of the invention comprise an expandable portion which is covered with a sponge coating for release of at least one biologically active material. The sponge coating is made of a non-hydrogel polymer having a plurality of voids. The device can further include means for infusing or expelling the biologically active material or drug into the voids. The drug is delivered to the body lumen of a patient by expelling the drug and inflating or expanding the expandable portion of the catheter or device. | 03-12-2009 |

| 20100123784 | Catadioptric Projectors - Herein is presented a catadioptric projector by combining a commodity digital projector with additional optical units. By using specially shaped reflectors and/or refractors, a catadioptric projector can offer an unprecedented level of flexibility in aspect ratio, size, and field of view. Also presented, are methods to reduce projection artifacts in catadioptric projectors, such as distortions, scattering, and defocusing. By analysis of projection defocus of reflector and thin refractor based catadioptric projectors, it is shown that defocus blur can be interpreted as spatially-varying Gaussian blurs on an input image. Kernels are measured directly from a light transport matrix, T, and de-convolution is applied to optimize an input image. Practical uses of catadioptric projectors in panoramic and omni-directional projections are also demonstrated. | 05-20-2010 |
