Catheter devices and methods are provided for enhancing fluid flow through a vascular site occupied by a calcified lesion. The catheter devices of the subject invention at least include, at their distal end, a proton generating means, and in many embodiments also include a flushing means. In using the subject devices, the distal end of the catheter is placed proximal to the vascular occlusion and protons are generated, e.g., via proton generation from water, in a manner sufficient to reduce the pH of the vascular site in the region proximal to the occlusion. The subphysiologic pH is maintained for a period of time sufficient for fluid flow through the vascular site to be enhanced. Also provided are kits comprising the subject catheter devices for use in the subject methods.

Methods and compositions are provided for preparing storage stable partially neutralized acid compositions. The partially neutralized acid compositions are amenable to prolonged periods of storage. Following storage, the acids can be neutralized with a calcium neutralizing source and combined with a lubricant to form a rapidly setting calcium phosphate mineral suitable for a variety of purposes, e.g. bone replacement.

The invention involves a novel method of increasing the efficiency of a thermal engine. Heat is generated by a non-linear chemical reaction of reactants, said heat being transferred to a thermal engine such as Rankine cycle power plant. The novel method includes externally perturbing one or more of the thermodynamic variables of said non-linear chemical reaction.
