Abstract:
An enhanced wavelength-converting structure is disclosed. The enhanced wavelength-converting structure includes a substrate, a wavelength-converting layer arranged next to the substrate, and a wavelength-selective reflecting layer arranged next to the wavelength-converting layer. The wavelength-converting layer converts the first light into the second light. A part of the second light radiating backward to the light source is further reflected toward the substrate by the wavelength-selective reflecting layer to form the enhanced second light by combining with another part of the second light radiating toward the substrate.
Abstract:
The white LED module includes a packaging housing having a containing chamber, an LED chipset disposed in the containing chamber, and a shared flat wavelength-converting structure disposed on the packaging housing. The LED chipset could illuminate an original light with at least two wavelengths. The original light may be diffused with the shared flat wavelength-converting structure and may be partially converted into a converted light with the shared flat wavelength-converting structure. The converted light and the original light are mixed to form a white light.
Abstract:
A wavelength converting structure is provided. The wavelength converting structure comprises the following:a substrate, anda wavelength converting coating which is deposited on the substrate and comprises:(a) a phosphor powder which can be excited by UVC; and (b) an anti-UVC adhesive, wherein the thickness of the wavelength converting coating is 2 to 10 times the average particle size of the phosphor powder and the amount of the phosphor powder in the wavelength converting coating conforms to at least one of the following requirements:(i) the phosphor powder should be about 30% to 85% by volume of the wavelength converting coating based on the total volume of the phosphor powder and the adhesive; and(ii) the weight ratio of the phosphor powder to the adhesive should range from 1:1 to 20:1.The wavelength converting coating can effectively convert UVC to visible light to provide a visible light source with a high surface area.
Abstract:
An electrophysiology catheter and method of use for mapping and ablation procedures. The catheter includes a braided conductive member at its distal end that can be radially expanded. The catheter can be used in endocardial and epicardial mapping and ablation procedures.
Abstract:
Method and apparatus for treating conductive irregularities in the heart, particularly atrial fibrillation and accessory path arrythmias. An ablative catheter is positioned relative to an inter-atria electrical pathway, or a vicinity of accessory paths such as the coronary sinus or fossa ovalis, and actuated to form a lesion that partially or completely blocks electrical conduction in at least one direction along the pathway.

Abstract:
A method for determining a change in function of a patient's heart that includes the steps of collecting seismocardiographic (SCG) data corresponding to a heart motion of the patient's heart; determining a hemodynamic parameter based on the SCG data; and comparing the parameter with a predetermined measure of cardiac performance. The system used with the method includes one or more accelerometer sensors, a computer data analysis module, and may also include a 2D and 3D visual graphic display of analytic results, i.e. a Ventricular Contraction Map.
Abstract:
An electrophysiology system for mapping and/or ablating tissue includes a catheter having a plurality of electrically active sites. The system includes a controller providing a user interface through which the plurality of sites may be controlled. The sites may be accessed individually or in groups. In addition, the order and timing of the accessing of specific electrically active sites may be controlled in a manual or automated fashion.
Abstract:
Systems and methods to assist in locating the focus of an atrial fibrillation include the association of atrial fibrillation cycle length values and statistics relating thereto with temporal locations on an electrogram of a given electrode, and/or the coordination of electrode locations with respective the spectral analyses of electrogram signals and further parameters and statistics relating thereto. Ablation therapy can proceed under guidance of such information.
