    摘要： A medical device for treating a defective heart valve. The medical device comprises a distal anchoring member for disposing in a blood vessel. A proximal anchoring member for disposing in or at an entrance of the blood vessel. A telescoping assembly coupling at a first end to the distal anchoring member and at a second end to the proximal anchoring member. The telescoping assembly is deployable into the blood vessel. The telescoping assembly reduces a distance between the distal anchoring member and the proximal anchoring member, wherein the telescoping assembly comprises of at least two members capable of sliding into each other giving the telescoping assembly adjustable lengths.

    摘要： Methods and apparatus for localization, diagnosis, contact or activity detection of bio-electric tissue providing improved sensitivity to the distance between a sensing electrode and bio-electric tissue and providing the means to measure the impedance of the tissue between a sensing electrode and bio-electric tissue. In accordance with the method, a controlled effective input impedance is provided to the monitor, which input impedance can be set to cause a significant portion of the bio-electric tissue signal to be dropped across the tissue between a sensing electrode and the bio-electric tissue when the two are separated by a predetermined or arbitrary distance. Various illustrative embodiments and forms of construction are disclosed.

    摘要： An echogenic medical device, such as a needle catheter, which produces an improved ultrasonic image of the device, and a method of performing a medical procedure using a device of the invention. One aspect is directed to a catheter which reduces artifacts in the ultrasound image of the catheter. In one embodiment, the catheter has a spherical distal tip. Another aspect of the invention is directed to an echogenic catheter with echogenic portions arranged in an array to facilitate determination by ultrasonic imaging of the rotational orientation of the catheter relative to a desired location within the patient.
