Filed:

Jan 30, 2001

Appl. No.:

09/774469

Inventors:

Peter Johansson - Campbell CA
David Delaney - Los Gatos CA
Brent Constantz - Menlo Park CA

Assignee:

Corazon Technologies, Inc. - Menlo Park CA

International Classification:

A61M 3100

US Classification:

604507, 604508, 604509, 604264, 604 9601, 604912

Abstract:

Methods of enhancing fluid flow through a vascular site occupied by a vascular occlusion, as well as systems and kits for use in practicing the same, are provided. In practicing the subject methods, the vascular site is flushed simultaneously with a first dissolution fluid (e. g. , an organic matter dissolution fluid and/or an inorganic matter dissolution fluid), and a second dissolution fluid attenuating fluid, where flushing is carried out in a manner such that only a surface of the vascular occlusion is contacted with the non-attenuated dissolution fluid. Examples of dissolution fluid/dissolution fluid attenuating fluid pairs include: (1) oxidizing agent fluid and fluid comprising oxidizable neutralizing agent; (2) surfactant fluid and phosphate buffered saline; (3) acidic solution and phosphate buffered saline; etc. Flushing is carried out in this manner for a period of time sufficient for fluid flow through the vascular site to be enhanced, e. g. increased or established.

Abstract:

Methods and compositions for producing flowable compositions, e. g. pastes, that set into calcium phosphate products are provided. In the subject methods, dry reactants that include a calcium source and a phosphate source are combined with setting fluid to produce the flowable composition. A feature of the subject methods is that the dry reactants include a particulate calcium and/or phosphate reactant having a mean particle size of less than about 8 μm and narrow size distribution. Also provided are the compositions themselves as well as kits for use in practicing the subject methods. The subject methods and compositions produced thereby find use in a variety of applications, including the repair of hard tissue defects, e. g. , bone defects.
