  • Patent number: 8167933
    Abstract: An annuloplasty system for repairing a valve in a patient's heart comprises a surgical implant including a member having first and second end portions. The implant member further is configured and/or adapted to form a partial ring along a portion of one of the valve annulae of a patient's heart such as the mitral or tricuspid valve annulus. The implant member is axially elastic such that it can axially expand and contract and includes first and second anchors extending from the end portions of the implant member. The anchors are adapted to anchor the implant in tissue such as the mitral or tricuspid valve annulus. The system can facilitate tissue plication (e.g., of the posterior annulus of the mitral valve or the annulus of the tricuspid valve) and reinforcement of a valve annulus.

  • Patent number: 8170987
    Abstract: Methods, systems and computer program products facilitate intelligent, automatic selection of content on consumer electronic devices to be backed up. User-defined rules selectively and automatically back up content and/or metadata about the content to a network, to another external device, or to an internal chip or memory. Via a user-friendly interface, users can initially set up rules for content backup, and thereafter, content backup can occur automatically. Stored back up content can be replicated on a device, for example, when the content has become corrupted on the device, when the content is lost, and/or when the CPE device crashes.

  • Patent number: 8168199
    Abstract: A method for therapeutically treating an animal, including a human, for psychosomatic, depressive and neuropsychiatric diseases, such as anxiety, depression, insomnia, schizophrenia, epilepsy, spasm and chronic pain. Administration of a suitable DP IV inhibitor causes the reduction of activity in the enzyme dipeptidyl peptidase (DP IV or CD 26) or of DP IV-like enzyme activity in the brain of mammals and leads as a causal consequence to a reduced degradation of the neuropeptide Y (NPY) and similar substrates by DP IV and DP IV-like enzymes. Such treatment will result in a reduction or delay in the decrease of the concentration of functionally active neuronal NPY (1-36). As a consequence of the resulting enhanced stability of the endogenous NPY (1-36) caused by the inhibition of DP IV activity, NPY activity is prolonged thereby resulting among other things in functionally active NPY Y1 receptor activity thereby facilitating antidepressive, anxiolytic, analgesic, antihypertension and other neurological effects.

  • Publication number: 20120101442
    Abstract: Described herein are devices and methods for guide catheters having one or more regions of increased flexibility. A flexibility region comprises one tubular segment of the guide catheter with a non-linear longitudinal seam between two non-concentric layers of material having different durometers. A non-linear seam, such as a zig-zag or sinusoidal configuration, permits controlled compression of lower durometer material between portions of higher durometer material.

  • Publication number: 20120100364
    Abstract: Provided is a method of arranging particles on a substrate, the method including: (a) preparing a substrate, a surface of which has depressions or projections capable of fixing the positions and/or orientations of one or more particles; and (b) placing the particles on the substrate and applying a physical pressure to the particles so that a portion or the whole of each particle is inserted in each of pores defined by the depressions or the projections. Provided is also a method of arranging particles on a substrate, the method including: (a) preparing a substrate, at least a surface portion of which has adhesive property; and (b) placing particles, which do not have flat facets but curved surfaces, on the substrate and applying a physical pressure to the particles so that the particles are immobilized on adhesive surface portions of the substrate.

  • Publication number: 20120101334
    Abstract: An endoscopic imaging system for examining a patient's body cavity includes an endoscope having a distal end, a proximal end and a number of lumens therein. One or more distal gas ports are disposed at or adjacent the distal end of the endoscope and one or more proximal gas ports are disposed proximal to the distal gas ports. Insufflation gas is delivered to the distal gas ports and withdrawn from the proximal gas ports or vice versa such that a gas bubble is formed in the body cavity and travels with the distal tip of the endoscope.
