International Classification:

A61F 2/06

US Classification:

623001380

Abstract:

Non-fragmenting low friction bioactive absorbable coils are disclosed that improve long-term anatomic results in the endovascular treatment of intracranial aneurysms. The coils are composed of at least one biocompatible and bioabsorbable polymer. The coils are then coated with a polymer to reduce the friction. The coating can contain drugs, such as growth factors, and can be used to accelerate histopathologic transformation in aneurysms. The coil can be a polymer such as polyglycolic acid (PGA), poly-L-lactic acid (PLLA), polycaprolactive, poly-L-lactide, polydioxanone, polycarbonates, polyanhydrides, polyglycolic acid/poly-L-lactic acid copolymers, polyhydroxybutyrate/hydroxyvalerate copolymers, or combinations thereof.

US Classification:

34235724, 34235738, 34235744

Abstract:

A differential global positioning system (DGPS) processor can include an almost fixed integer ambiguity (AFIA) module for generating in real-time a multiple dimensional state vector of integer ambiguities and multiple dimensional corrections. The AFIA module can use double difference (DD) measurements for pseudo-range (PR) and carrier phase (CP) pairs generated from at least three global positioning system (GPS) receivers. A DGPS processor can be included in a high data rate real time attitude determination (RTAD) system to achieve high heading accuracy with high integrity.
