Abstract:
A power amplifier system is presented for use in amplifying an RF input signal comprising N sub-power amplifiers are connected together in parallel with each receiving and amplifying a portion of the RF input signal. A combiner combines the amplified portions of the RF input signal to provide a combined output signal. Each sub-amplifier includes at least one transistor having an input port that receives a DC bias voltage and an output port, such that when the RF input signal is not present a quiescent current flows through the output port. A controller is operative when the RF signal is not present to check and adjust the magnitude of the quiescent current flowing in each of the sub-amplifier output ports in the sequence of 1. . . N.
Frequency Verification Of An Amplitude Modulated Signal
An apparatus and method are disclosed for verifying the frequency of an AM carrier signal having a target frequency. The apparatus includes a high frequency clock that produces a clock signal having a higher frequency than the target frequency. A counter is advanced by the clock signal and reset after each cycle of the carrier signal. A first comparison portion compares the value recorded by the counter to a first reference value, and a second comparison portion compares the value recorded by the counter to a second reference value. An error determination portion attenuates the carrier signal if the comparisons conducted by the first and second comparison portions indicate an error condition.

Abstract:
A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable handpiece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. The reusable handpiece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. The motor also actuates an attached sample revolver drum assembly in coordination with movement of the cutter tube to provide sequentially stored tissue samples in a sample storage bandolier that is rotated about a revolver cylindrical drum.

External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.

US Classification:
600567
Abstract:
A biopsy device comprises a probe body, a cannula extending distally from the probe body, a cutter moveable relative to the cannula to sever tissue, and a tissue sample holder coupled with the probe body. The tissue sample holder comprises a rotatable member and at least one removable member secured about the exterior of the rotatable member. The at least one removable member defines a plurality of tissue sample compartments. Each tissue sample compartment is configured to receive one or more tissue samples captured by the cutter. In some versions, the at least one removable member comprises a belt and a plurality of vials.

Abstract:
A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.

Abstract:
A biopsy system includes a first external device, a second external device and a control module interface. The control module interface is in electrical communication with both the first and second external devices, and the control module interface is in mechanical communication with the second external device. The control module interface is configured to be positioned remotely from at least one of the first and second external devices. The control module interface comprises a motor, operational electronics, a shaft connector assembly, an electrical connector and a cabinet configured to house the motor and operational electronics. The motor is in mechanical communication with the second external device via a mechanical cable. The operational electronics are configured to permit control of the motor and a motorized component of the second external device. In some embodiments, the mechanical cable comprises a flexible shaft cable, such as a speedometer cable.
