Assignee:

Micro Therapeutics, Inc. - Irvine CA

International Classification:

A61F 200

US Classification:

604 28, 604 9601, 523113, 424423

Abstract:

Disclosed are novel methods for embolizing blood vessels comprising delivering, via a catheter, an embolic composition comprising a biocompatible polymer, a biocompatible water insoluble contrast agent, and a biocompatible solvent. In one embodiment, the method is conducted during a single surgical procedure whereby a flow-arresting device is positioned and activated at the vascular site to be embolized, the embolic composition is injected, and the flow-arresting device is deactivated. In another embodiment, the method is conducted during a single surgical procedure whereby two embolic compositions, situated adjacent to one another, are injected at the vascular site to be embolized.

Appl. No.:

10/236414

Inventors:

Assignee:

The DIRECTV Group, Inc. - El Segundo CA

International Classification:

H03D 1/04

US Classification:

375346, 375227, 375 E103, 398 26, 455 6713, 455135, 4552263, 4552772, 702 69

Abstract:

Systems and methods are presented for measuring power levels of primary and interfering signals as well as noise, particularly for satellite transmitted signals. A typical method comprises the steps of receiving a signal comprising a primary signal, an interference signal and noise, demodulating the primary signal to remove a carrier frequency, decoding the primary signal to obtain symbols, estimating a power level of the primary signal based upon the demodulated and decoded primary signal. Additionally, an ideal primary signal can be generated from the carrier power and frequency and the symbols and subtracted from the received signal to produce the noise and interference signal. The noise and interference power is then estimated from the noise and interference signal.
