Abstract: Devices and methods for nebulizing a fluid are described. A replaceable fluid assembly may include a reservoir and a fluid cartridge. The reservoir may be detachable from the fluid cartridge and may be assembled by the prior prior to loading into the nebulizing device.

Abstract: Described are devices and methods for treating degenerative, congestive heart disease and related valvular dysfunction. Percutaneous and minimally invasive surgical tensioning structures offer devices that mitigate changes in the ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities. These tensioning structures can be implanted within various major coronary blood-carrying conduit structures (arteries, veins and branching vessels), into or through myocardium, or into engagement with other anatomic structures that impact cardiac output to provide tensile support to the heart muscle wall which resists diastolic filling pressure while simultaneously providing a compressive force to the muscle wall to limit, compensate or provide therapeutic treatment for congestive heart failure and/or to reverse the remodeling that produces an enlarged heart.

Abstract: A method and apparatus for micro-dissection of vascular occlusions are provided wherein two or more tissue expansion members are coupled with a base section and an actuation assembly so that they rotate radially outward from the central axis of the base. The actuating assembly occupies a channel within the base such that it is free to move in a longitudinal direction. As an external force is applied to the actuation assembly, the actuation assembly engages the tissue expansion members causing them to move in a radial outward direction with respect to the base section. The resulting motion causes the tissue expansion members to contact the tissue walls and/or the occlusion. The tissue expansion members can stretch the tissue walls causing the occlusion to tear, fracture or be disrupted or displaced.
