Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: A medical packing device for use within a body cavity of a subject is provided. The medical packing device comprises an absorbent member having at least a first major side surface and at least one depression that is formed in the first major side surface and has a predetermined shape and volume. The at least one depression is defined by a continuous perimeter wall that is formed in the first major side surface and forms a reservoir capable of receiving and retaining a volume of a medicament therein.

Abstract: An apparatus (100) for orienting magnetic elements (14) for assembly on a flexible elongated core member (12) includes a plate (104) for supporting the magnetic elements (14). A plurality of magnetic positioning elements (150) are secured to the plate (104) and are configured to position and orient the magnetic elements (14) to facilitate assembly of the elements (14) on the core member (12).

Abstract: A medical device suitable for introducing a medical instrument into a patient includes an outer cannula and at least one arm connected to the cannula toward a proximal portion of the at least one arm. The at least one arm is deployable between a closed position and an open position. An inner member is telescopically received in the outer cannula to hold each arm in the closed position. The inner member is deployable to disengage from the arm after the device is inserted into a patient, thereby freeing the arm to be deployed to the open position where it helps hold the outer cannula in the patient. The inner member includes an inner cannula and/or a trocar.

Abstract: A medical device includes an outer catheter having a longitudinal axis, a movable device that can pass through the catheter and is movable along the longitudinal axis relative to the catheter, and a magnetic drive engine toward a distal end of the catheter. The magnetic drive engine includes at least two components with respective magnetic field-generating coils and magnets, that move relative to one another. One of the two components is coupled to the movable device for driving vibratory motion in the movable device along the longitudinal axis. An exemplary movable device is a guidewire over which the catheter is fed. The device typically includes a second catheter threaded inside the first catheter. The first or outer catheter shields the magnetic engine and its moving components.
