  • Methods and apparatus for localized and semi-localized drug delivery
    Publication number: 20050059931
    Abstract: A catheter system for localized or semi-localized administration of agents through the wall of a blood vessel is provided. Various catheter system constructions which use at least one expandable occluding device to create an isolated region are provided. Constructions using one catheter and one occlusion device are provided, along with constructions using two catheters and multiple occlusion devices. The catheter system may include a catheter with a variable stiffness along its length. The catheter system may also include a guide wire integrated with an inner catheter. The catheter can infuse the agent into the blood vessel in a pressure regulated manner. Methods for delivery and infusion of the agent within a blood vessel are also provided.

  • Non-invasive method and apparatus for diagnosing and monitoring aortic valve abnormalities, such a aortic regurgitation
    Patent number: 5879307
    Abstract: A method and device is provided for determining aortic valve abnormalities. The method first includes the step of providing a sphygmomanometer device for inducing a pressure on a body part of a patient. A data stream receiver is provided for receiving a stream of data relating to the pressure response of the pulsed fluid flowing through the cardiovascular system of the patient. A data processor is provided for processing the data to create a series of time dependant pulse wave forms. The data can be converted by Fast Fourier Transformation (FFT) to obtain Power Spectrum (PS) which comprises a frequency dependant array of pulse signals. Both of the time dependant and frequency dependant (Power Spectrum) data can be displayed and analyzed to help determine the condition of the aortic valve and the percentage of regurgitation of the patient.
