摘要： 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.

摘要： 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.

摘要： An electrical device for treating problem skin areas, including warts, has an electrode and a power source coupled to the electrode for generating an arc over a gap between a distal end of the electrode and a patient's skin when the electrode is placed in spaced proximity to the patient's skin. The power source provides electricity to the electrode with a frequency of at least 100 kHz, an open-circuit voltage of less than 2 kVRMS, and a total power of less than 2 W.
