摘要:
A mitral heart valve annuloplasty ring having a posterior bow that conforms to an abnormal posterior aspect of the mitral annulus. The ring may be generally oval having a major axis and a minor axis, wherein the posterior bow may be centered along the minor axis or offset in a posterior section. The ring may be substantially planar, or may include upward bows on either side of the posterior bow. The ring may include a ring body surrounded by a suture-permeable fabric sheath formed of a plurality of concentric ring elements or bands. The posterior bow is stiff enough to withstand deformation once implanted and subjected to normal physiologic stresses. A method of repairing an abnormal mitral heart valve annulus having a depressed posterior aspect includes providing a ring with a posterior bow and implanting the ring to support the annulus without unduly stressing the attachment sutures.

A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest.

An apparatus for implantation in the annulus of a tricuspid valve has an anterior annulus aspect, a posterior annulus aspect, and an atrioventricular (AV) node located adjacent the anterior annulus aspect. The apparatus includes an ovoid main body portion. The main body portion has an anterior body segment adapted for placement adjacent the anterior annulus aspect, a posterior body segment located opposite the anterior body portion and adapted for placement adjacent the posterior annulus aspect, and oppositely disposed left and right side body segments extending between the anterior and posterior body segments. At least two valve leaflets are secured within the main body portion and are coaptable to permit unidirectional flow of blood. A cushioned section is attached to the main body portion, coextends at with at least a portion of the main body portion, and is adapted for placement adjacent the AV node. A method for implanting the apparatus in the annulus of a tricuspid valve is also described.

System, method and program product for monitoring a computer program or database maintained by a service provider for a customer. A multiplicity of failures of the computer program or data base during a reporting interval are identified. The times of the multiplicity of failures are compared to one or more scheduled maintenance windows. A determination is made that at least one of the multiplicity of failures occurred during the one or more scheduled maintenance windows. A determination is also made that the customer was responsible for at least another one of the multiplicity of failures. A determination is made that the service provider was responsible for a plurality of the failures not including the at least one failure occurring during the one or more scheduled maintenance windows and the at least another one failure for which the customer was responsible. A determination is made whether the service provider complied with a service level agreement based on the plurality of the outages. This may be based on a percent time each reporting interval that the computer program had failed based on durations of the plurality of failures. The computer program may need information from another computer program or other database to function normally. If this other computer program or other database failed during the reporting interval, and the customer was responsible for the failure of the other computer program or other database, the service provider is not charged for the failure of the first said computer program. A determination is made as to a monetary cost to a business of the customer for the plurality of said failures.

Various methods and devices are disclosed for improving cardiac function in hearts having zones of infarcted (akinetic) and aneurysmal (dyskinetic) tissue regions. The methods and devices reduce the radius of curvature in walls of the heart proximal infarcted and aneurysmal regions to reduce wall stress and improve pumping efficiency. The inventive methods and related devices include splinting of the chamber wall proximal the infarcted region and various other devices and methods including suture and patch techniques.
摘要:
A molecular complex which comprises a biopolymer having a plurality of ionic functional groups and a conductive polymer having charges therein. The charges bind to the ionic functional groups to form the complex. The conductive polymer is selected from the group consisting essentially of polyaniline, polypyrrole, polythiophene, poly(phenylenevinylene) or poly(phenylene sulfide) and substituted versions thereof.
摘要:
A method and apparatus for updating firmware using a firmware-over-the-air update. The apparatus comprises a plurality of repository files each comprising one or more settings. The apparatus is configured to store a specified value corresponding to at least one of the settings. The apparatus is capable of receiving a firmware over-the-air update which overwrites at least one repository file with an updated version. The apparatus is capable of identifying repository files which have been changed by the update and for which at least one corresponding specified value exists. Identification is achieved by comparing representations of repository files. Further, the apparatus is capable of merging updated repository files to retain specified values.
