The dash board also can be used to assess the risk of the patient and safety assessment prior to the procedure.
2012-136 – A patient’s heart rate, systolic blood pressure, Braden Skin Scale (a nursing assessment), arterial oxygen saturation, and respiratory rate are entered into a simple mathematical equation that calculates the patient’s risk of having cardiac arrest, emergency transfer to the ICU, or Rapid Response Team activation in the next 2-12 hours. The calculation is made every time any one of those... Read More
2012-129 – A method to quantify tissue viscoelastic properties in a model-independent way by estimating the complex shear modulus from creep-recovery response and shear wave propagation speed by ultrasound acoustic radiation force.

2012-073 – Erectile dysfunction (ED) is estimated to affect 20-30% of men between the ages of 40-80 years. In cases of medication-resistant ED, surgical treatment, and especially penile prosthesis implantation is the standard of care. Complications of surgery can include neurovascular and urethral injury, and other tissue damage that can contribute to sub-optimal outcomes. A Mayo Clinic investigator... Read More
2012-004 – What is envisioned is a system of electrochemical and electrical monitoring coupled with directed stimulation to bypass damaged nerve tissue.

Further it is envisioned that a pump can be added to provide neural modular/growth factors to maintain the nerve... Read More
2011-274 – The invention uses ultrasound to measure the nonlinear mechanical properties of an object including those of biological tissues. This information can be used to detect abnormalities in tissues.
2010-296 – Communications between electronic components employ one of a number of signaling schemes. Generally, digital communications use one of two classes of signaling schemes: single-ended or differential signaling. A single-ended signaling channel employs transmission of n-level (typically 2-level) signals through a single signal conductor, using a ground or power conductor as the reference for... Read More
2009-314 – This disclosure is for a continuation-in-part to US Patent Application No: US 2006/0056310 A1. The original patent application uses only a symmetrical THRU structure for de-embedding. In this disclosure both OPEN and SHORT structures are presented as additional structures that, once measured with a VNA, can yield additional equations.
2009-281 – An ultrasound imaging system transmits a train of pulses along each scan line. The pulses are reflected at various depths and interfaces (objects). In color Doppler mode, the reflected signals from the corresponding scan line and depth correlated frame by frame. A loss of correlation is interpreted as object displacement and indicated by a color overlay. Even if an object does not move... Read More
2009-246 – In a communication system consisting of multiple nodes, optical interconnects and wave-division multiplexing (WDM), this can be used to broadcast the data stream from any one node-receivers using a broadcast element such as a star coupler. “All-in-all” or “many-to-all” nodes can thus be connected for high speed data transfer. At any receiver node, the optical signal contains all of the... Read More
Peritrode Minimally Invasive Cirmcumferential Peripheral Nerve Stimulation Electrode, Anchoring System and Placement Assist Device
2009-175 – An eight contact electrode placed “through the needle"via ultrasound visual guidance. The electrode is able to pass under a target nerve and curve over and reside circumferentially around the nerve in a "cuff” configuration thus facilitating efficient pain management.
2008-214 – The present invention is a circuit block used to condition and sample a variety of electrical signals in characterization and system applications. The internal passive circuitry eases characterization of high-speed differential and single-ended applications by providing impedance-matched environment and integrating unique capabilities such as true differential termination, pass-through...
