A method and apparatus are provided for protecting cardiac tissue from insult. The method comprises identifying the occurrence of an insult, such as a heart attack, and delivering electrical stimulation to one or more predetermined nerves in a patient's body in response to identifying the occurrence of the insult. The stimulation may be provided at the spinal canal or on the chest wall of the patient through cutaneous electrodes.

A method and apparatus to provide therapy to a patient for protecting cardiac tissue from insult is disclosed. The method comprises delivering closed loop electrical stimulation to one or more predetermined portions of a portion of excitable tissue of the spinal cord of a patient; and monitoring one or more physiologic indices of the body. That is, a closed-loop feedback controller is used to apply electrical stimulation to preselected regions of the spinal cord of a patient's body based upon one or more aspects of the physiologic indices.

In general, the invention features methods by which more than one client program connected to a network stores the same data item on a storage device of a data repository connected to the network. In one aspect, the method comprises encrypting the data item using a key derived from the content of the data item, determining a digital fingerprint of the data item, and storing the data item on the storage device at a location or locations associated with the digital fingerprint. In a second aspect, the method comprises determining a digital fingerprint of the data item, testing for whether the data item is already stored in the repository by comparing the digital fingerprint of the data item to the digital fingerprints of data items already in storage in the repository, and challenging a client that is attempting to deposit a data item already stored in the repository, to ascertain that the client has the full data item.

Described herein are devices, methods and kits for assessing and / or enhancing the accessibility of a subvalvular space of a heart, accessing the subvalvular space of the heart (e.g., to provide access for one or more other devices), and / or positioning one or more devices in the subvalvular space of the heart. The devices described herein may, for example, comprise catheters that may be used to manipulate one or more chordae tendineae, diagnostic catheters having different sizes and / or shapes (e.g., different curvatures), guide catheters having different sizes and / or shapes (e.g., different curvatures), and visualization catheters. In some variations, the devices, methods, and / or kits may be used to visualize a target site, such as a subannular groove of a heart valve. In certain variations, the devices, methods, and / or kits may be used to manipulate chordae tendineae to provide additional space in a ventricle of a heart (e.g., enhancing the accessibility of the ventricle).

Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a collapsible seat disposed within the bore. The seat has a first position defining a first seat inner diameter when the apparatus is in the run-in position and a second position defining a second seat inner diameter when the apparatus is in the set position. The first seat inner diameter is greater than the second seat inner diameter. A plug element is adapted to be disposed into the bore and landed on the seat to move the seat from the first position to the second position. While in the second position, the seat restricts fluid flow through the bore and provides additional support to the plug member landed on the seat.

A process for designing and manufacturing precision-folded, high strength, fatigue-resistant structures and a sheet therefore. The techniques include methods for precision bending of a sheet of material (41, 241, 341, 441, 541) along a bend line (45, 245, 345, 445,543) and a sheet of material formed with bending strap-defining structures, such as slits or grooves (43, 243, 343, 443, 542), are disclosed. Methods include steps of designing and then separately forming longitudinally extending slits or grooves (43, 243, 343, 443, 542) through the sheet of material in axially spaced relation to produce precise bending of the sheet (41, 241, 341, 441,541) when bent along the bend line (45, 245, 345, 445, 543). The bending straps have a configuration and orientation which increases their strength and fatigue resistance, and most preferably slits or arcs are used which causes edges (257, 457) to be engaged and supported on faces (255, 455) of the sheet material on opposite sides of the slits or arcs. The edge-to-face contact produces bending along a virtual fulcrum position in superimposed relation to the bend line (45, 245, 345, 445, 543). Several slit embodiments (43, 243, 343, 443, 542) suitable for producing edge-to-face engagement support and precise bending are disclosed, as is the use of the slit sheets to produce various three-dimensional structures and to enhance various design and fabrication techniques.

A powered driver and methods are disclosed, the driver including a head having a gapped jaw and housing a motor driven drive transfer assembly for operating a rotatable split socket engageable at a threaded connector. A reaction unit is movably maintained through the head, and a probe is associated with the reaction unit. The methods of this invention include setting a selected rotational limitation at the driver relating to fitting characteristics, operating the driver to cause relative rotation of a connector nut located in the socket and connector body engaged by the reaction unit. One of a plurality of operational modes for driver operations is selected and relative movement of the head and reaction unit are monitored during driver operation. The driver is controlled so that driver operation ceases when a selected combination of events related to operational mode selected and at least one of rotational limitation setting, monitored relative movement or driver operation occurs.

The present invention relates to methods and devices that help to curb appetite and / or reduce food intake. In one embodiment, the methods and devices of the present invention include a small intestinal / duodenal insert comprising an elongated member with at least one flow reduction element that can cause the stimulation of one or more biological signals of satiety.
