Method and apparatus for ultrasound guided intravenous cannulation
InactiveUS6132379AEasy to operateQuick buildBlood flow measurement devicesOrgan movement/changes detectionVenous accessDual mode
A dual mode handheld ultrasonic device is provided for guiding a venous access catheter into a patient's peripheral vein. It provides B-mode imaging with a predetermined aperture and operating frequency which locates and displays a gray scale cross-sectional image of the target blood vessel. A single doppler beam in a separate mode detects the same blood vessel and creates a single scanline image superimposed to such B-mode cross-sectional image. Simultaneously, the intensity of the positive doppler shift detected by the single doppler beam as it hits the target blood vessel activates a plurality of light emitting diode (LED) indicator lights with varying voltage requirements mounted in the scanhead. Activated LED indicator lights forms an arrow pointing inferiorly perpendicular to the target vessel which guides a physician or a paramedical professional to the precise catheter insertion spot on a patient's extremity while simultaneously viewing the target blood vessel's cross-section on the display screen.

InactiveUS20050222532A1Improve efficiencyEasy to useStentsBalloon catheterExtracorporeal circulationVenous blood
This invention relates to a venous cannula for use in conjunction with cardiovascular examinations, treatments and surgery. The venous cannula is configured for two-stage drainage of oxygen-depleted venous blood from a central venous location via a peripheral venous insertion site, such as a femoral vein. The venous cannula is optimized for use in a cardiopulmonary bypass system that includes a multichannel arterial perfusion catheter. The cardiopulmonary bypass system is advantageous for use in performing standard open chest or least invasive cardiac surgical procedures.

High intensity focused ultrasound for imaging and treatment of arrhythmias
InactiveUS20050267453A1Shorten treatment timeAutomate processingUltrasonic/sonic/infrasonic diagnosticsUltrasound therapySonificationDual mode
A dual-mode, capable of imaging and ablation, ultrasound array integrated in a catheter is provided for minimally invasive treatment of arrhythmias. The catheter array is small enough for insertion through a peripheral vein and is longitudinally integrated with the catheter to have a side-view for tissue imaging and ablation. A high length / width array ratio creates a large aperture necessary for high power ablation densities. A catheter stabilization device maintains a distance between the catheter array and the wall of a heart or vein. Visualization of anatomy and imaging of ablated tissue provides a guide for placing the lesion and assists in achieving a pattern of ablated tissue. The catheter is advanced to another area by catheter rotation and / or array steering or focusing. Gating the imaging and ablation processes to a heart cycle allows for accounting and compensation of heart motion and enables automation of an arrhythmia treatment.

Systems and methods are provided for monitoring changes in blood volume using waveforms in the peripheral vasculature. In particular, the systems and methods relate to detecting ventilation-induced variation (VIV) of waveforms in the peripheral vasculature. Advantageously, the systems and methods may relate to analyzing VIV in peripheral venous pressure (PVP). Thus, the VIV of PVP may be measured, wherein decreased VIV is indicative of decreased blood volume In exemplary embodiments, such as involving spontaneous breathing, it may be necessary to account for changes in respiratory signal strength. Thus systems and methods are also provided for assessing coherence between ventilation and VIV for a flow or pressure waveform. Specifically, coherence is evaluated by comparing the waveform to a detected respiratory signal. Finally, systems and method are provided for distinguishing the impact of respiration on the PG signal during hypervolemia as compared to hypovolemia. Such systems and methods may advantageously be utilized to monitor fluid status during fluid replacement.

Aspects of the invention relates to systems and methods for hypovolemia and / or hypervolemia detection of a living subject using peripheral intravenous waveform analysis. In one embodiment, the method includes: acquiring, from a vein of the living subject, peripheral venous signals; performing a spectral analysis on the acquired peripheral venous signals to obtain a peripheral venous pressure frequency spectrum; and performing a statistical analysis on amplitudes of peaks of the peripheral venous pressure frequency spectrum to determine the blood volume status of the living subject in real time. Specifically, at least two peaks, respectively corresponding to a first frequency and a second frequency, are obtained on the peripheral venous pressure frequency spectrum. Amplitude change of the second peak is used to determine the blood volume status of the living subject. Hemorrhage may be detected when a significant amplitude decrease is detected from the second baseline peak to the second peak.
