Abstract:
The present invention provides a nonvolatile flash memory comprising a data storage space having a first erase block and an active partition, wherein the first erase block comprises an MBR. The active partition comprises a boot sector followed by a master FAT, a backup FAT and a root directory. The first erase block is disposed outside of the active partition such that the flash memory remains operable even if the boot sector and FAT become corrupted.

Abstract:
A catheter and catheter system may be used to treat disease tissue by gentle heating in combination with gentle or standard dilation. An elongate flexible catheter body with a radially expandable balloon having a plurality of electrodes engages tissue including diseased tissue when the structure expands.

Abstract:
A catheter and catheter system can use energy tailored for remodeling and/or removal of target material along a body lumen, often of atherosclerotic material of a blood vessel of a patient. An elongate flexible catheter body with a radially expandable structure may have a plurality of electrodes or other electrosurgical energy delivery surfaces to radially engage atherosclerotic material when the structure expands. An atherosclerotic material detector system may measure and/or characterize the atherosclerotic material and its location, optionally using impedance monitoring.

Abstract:
Methods and systems are disclosed for treating diseased tissue by gentle heating. The method induces vasodilation on tissue disposed about an lumen having both healthy tissue and diseased tissue. The method includes coupling a probe surface to the luminal tissue at a target location and transmitting desired quantities of tissue remodeling energy from the coupled probe into each of a plurality of discrete remodeling zones in the luminal tissue so that the tissue remodeling energy heats the plurality of remodeling zones, the remodeling energy being configured to avoid muscular contraction and inhibit both acute and long-term occlusion of the lumen.

Abstract:
Methods and systems for heating a body tissue region adjacent a body lumen with diseased and healthy portions using selective accumulation of energy in the artery tissue with or without knowledge of tissue topography. The method Includes positioning an energy delivery portion of a catheter body within the lumen adjacent the body tissue region to be heated, determining a pulse characteristic in response to a thermal property of a first tissue type and applying pulsed energy with the pulse characteristic from the energy delivery portion so as to therapeutically treat the second tissue type within the body tissue region by drawing heat from the first tissue type at a rate that avoids significant thermal damage to the first tissue type while building-up heat in the second tissue type.
