Abstract:

A method for electrospinning nanofibers having a core-sheath, tubular, or composite structure is disclosed. The process uses a spinneret having first and second capillaries that channel first and second fluids in the spinneret, the second capillary surrounding the first. A high voltage is applied between the spinneret and a spaced conductive collector. In one embodiment, the first fluid is a mineral oil and the second fluid is a polymeric solution that may include a polymer, a catalyst, a solvent, and a sol-gel precursor. The as-spun nanofiber includes an oil core and a composite sheath. The oil may be removed to produce a composite tubular fiber or the polymer and oil may be removed by calcination to produce a ceramic tubular fiber. In other embodiments, miscible fluids are used to produce porous nanofibers, selected additives functionalize the surfaces of the nanofibers and/or conjugated polymers are used.

C08G 73/00
B05D 5/12

US Classification:

252500, 528422, 427 58

Abstract:

A new method for forming stable polyaniline nanofiber colloids uses electrostatic repulsion to maintain dispersion of the nanofibers and prevent aggregation during synthesis of the nanofibers. The colloidal suspensions are formed directly from the reactants in solution maintained at a pH of about 1. 0 to about 4. 0 and a temperature of about 10 C. to about 100 C. with minimal or no stirring. Also set forth are new methods for forming ultrathin films of polyaniline nanofibers via self-assembly.

Assignee:

Cardiac Pacemakers, Inc. - St. Paul MN

International Classification:

A61N 1/05

US Classification:

607119

Abstract:

Various implantable medical device embodiments stimulate an autonomic neural target from within a pulmonary artery, and comprise at least one electrode, a power supply, a neural stimulator connected to the power supply, and an anchor structure. The neural stimulator is configured to generate a neural stimulation signal for delivery to the neural stimulation target through the at least one electrode. The anchor structure is configured to chronically and securely implant the neural stimulator, the power supply and the at least one electrode within the pulmonary artery. The anchor structure, the neural stimulator, the power supply and the at least one electrode are configured to be implanted through a pulmonary valve into the pulmonary artery. In various embodiments, the neural stimulator is configured to be operational to implement a neural stimulation protocol when chronically implanted within the pulmonary artery without a wired connection through the pulmonary valve.

Abstract:

This invention provides a class of dual mode imaging tracer capable of acting both as a fluorescent imaging tracer and a positron emission tomography imaging tracer. Tracers in accordance with this invention generally have a fluorescent core with a boron-fluoride element embedded therein. Exemplary embodiments of the tracer include F-labeled BODIPY compounds and derivative thereof. Also provided are tracer kits containing a sterile formulation of a BODIPY dye either in a radio-labeled or pre-labeled state, and methods for imaging heart perfusion using the F-labeled dual mode tracers.
