Aspiration systems and methods for controlling blood loss during thrombus removal are disclosed herein. The systems include an aspiration catheter, an aspiration tubing, a receptacle for collecting aspirated blood, a vacuum line coupled to the receptacle, and a sensor configured to measure a flow parameter associated with a liquid within an aspiration lumen. The systems further include a regulator configured to adjust a vacuum pressure within the vacuum line, and a vacuum controller operably coupled to the sensor and the regulator. The vacuum controller is configured to receive the flow parameter from the sensor, compare the flow parameter to a target range for the flow parameter, and send an automatic control signal to the regulator based on a comparison of the flow parameter to the target range. The automatic control signal causes the regulator to adjust the vacuum pressure within the vacuum line.

Thrombus aspiration system and methods for controlling blood loss

A method of controlling a power supply using software comprises setting a nominal output level through a waveform controlled by a micro-controller. The method identifies when a device is fully charged, and moves to a keep-alive mode, in which the output level is decreased below the nominal output level when the device is fully charged. The method further provides a failsafe to move the system to the keep-alive mode when the micro-controller is halted, crashed, in an error state.

Charger

The present invention provides an Electro Surgical Generator (ESG) optimized for lung biopsy. The ESG is exclusively battery operated and fits within the handpiece of modern endoscopic electrosurgical/electrocautery instruments, thereby avoiding wires, adapters, and coupling mechanisms. The ESG is adaptable to generate different waveforms that vary with respect to frequency, pulse width, amplitude, etc. through the use of timing circuits and voltage control (i.e. transformers). The ESG is both energy-efficient and safe. A closed loop feedback system featuring a monitor and controller ensure no more power than necessary is provided to achieve a goal current level. Dynamic Power Control (DPC) and Dynamic Temperature Control (DTC) systems vary power to maintain temperature with the lowest possible power. These features prolong battery life and guard against tissue damage. The generator includes other safety features such as resiliency against and the ability to overcome single fault events such as short circuits.

Minigenerator

A pointing device adapted to allow a user to set a pointing arrow to point towards another location, such as a city in another country. The pointing arrow is adapted to not point in a direction along the surface of the earth but to point accurately through the Earth. An apparatus including a pointing device and a calculation portion adapted to allow the user to determine how to point the pointing arrow towards the desired location. The calculation portion may include an electronic device and may include the use of a global computer network.

Apparatus and method for indicating direction

A multi-directional RFID read/write antenna unit is described which provides multi-directional RF communication to a source, such as a RF tag. The antenna comprises a plurality of coils adapted to transmit multi-directional RF signals to a RF tag and receive RF response signals from the RF tag. The RF antenna includes a switch for selecting at least one of the RF antenna coils for transmission of the RF signals and receipt of the RF response signals whereby the RF signals can be directed toward and received from a plurality of different directions from a fixed position.
