IPC: A61M29/00
Filed: 2003-10-16
Abstract: An improved embolic filter frame (31) has looped support struts (34). The frame provides enhanced longitudinal compliance, improved sealing against a vessel wall and a short deployed length. The struts (34) have a high degree of radial stiffness with a low degree of longitudinal stiffness. The loop support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter (92), the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced. When the delivery catheter constraint is removed during deployment, the struts "snap open" and assume a looped configuration which exert a high degree of force onto the vessel wall, creating an enhanced filter to vessel wall seal. In addition, the looped struts (34) and the central collar (46) connecting the support struts to the support wire (36) are positioned essentially within the plane of the filter opening. The overall deployed length of the embolic filter (40) is reduced.

Abstract: Disclosed is a method for calibrating smart antenna array systems in real time. Transmitting and receiving compensation coefficients of each antenna element relative to a calibration antenna element are obtained in the pre-calibration of a smart antenna before installation. After the antenna array is installed, in the transmitting calibration, a plurality of transmitting links simultaneously transmit calibration signals, then the base-band signal processor computes the amplitude and phase response of each transmitting link according to the calibration signals received by the calibration link and computes, together with the transmitting compensation coefficient obtained in the pre-calibration, the compensation coefficient of each transmitting link to compensate the downlink data of the base station; in the receiving calibration, the calibration link transmits a calibration sequence of signal, the base-band signal processor computes the amplitude and phase response of each receiving link based on the signals received by the receiving links and computes, together with the receiving compensation coefficient obtained in the pre-calibration, the compensation coefficient of each receiving link to compensate the uplink data of the base station. The calibration signal of each antenna element is generated by a periodic cycling shift of a basic calibration sequence. <IMAGE>
