Abstract:

A backup computer storage system that protects and/or recovers data on a primary computer storage system is disclosed. The backup computer system may be used to backup databases, files, and/or applications. In some embodiments, the backup system may be used to backup an image of the primary computer system. In other embodiments, the backup system may be used to backup one or more databases. In some embodiments of the present invention, the backup system replicates an image of data that is on a primary computer system. The backup system may also be used to restore data from the backup system to the primary computer system. In some embodiments, the backup system may restore data to a database while non-affected portions of the database are available and can be used. In some embodiments, the backup system records all transactions in real time without overwriting any previously stored backup data. In some embodiments of the present invention, the backup system maintains historical and/or chronological information related to the backed up data.

International Classification:

A61B017/08

US Classification:

606/153000

Abstract:

Angled anastomosis devices and associated methodology are described herein. Connector and connector components as well as tools associated therewith are disclosed. The connectors are adapted to produce an angled end-to-side anastomosis at a graft/host vessel junction. A fitting alone, or a fitting in combination with a collar may be used as a connector. Each fitting may be deployed by deflecting its shape to provide clearance for a rear segment that rotates about adjoining hinge section(s) so to fit the connector within an aperture formed in a host vessel. Upon return to a substantially relaxed position, a trailing or heel segment anchors the fitting in place. The angled fitting may include additional side features for interfacing with the host vessel. The collar may include features complimentary to those of a fitting and provisions for securing the graft to the host vessel.

International Classification:

A61B 1710

US Classification:

606205

Abstract:

The present invention is a lightweight endoscopic instrument which has a flushing port with a check valve assembly therein. The check valve retains carbon dioxide which is used during endoscopic procedures. Upon removal of the instrument, a pressurized fluid can be connected to the flush port, with internal seals directing the pressurized fluid through an annular space between the stem of the instrument and a central actuating rod or element so that any tissue or blood which may have entered into such annular space is flushed out the distal end of the instrument. The instrument features a knob allowing it to rotate on its longitudinal axis while having a handle that can be held in a fixed position by the surgeon. An index mechanism is provided to audibly and/or visually give an indication at preset increments of rotation. The instrument is lightweight to decrease fatigue and is simply and economically constructed.
