A tissue-removing catheter for removing tissue in a body lumen includes an elongate body. A tissue-removing element mounted on a distal end portion of the elongate body. The tissue-removing element includes a body including an exterior surface having a first segment extending from a proximal end...
A tissue-removing catheter for removing tissue in a body lumen includes a tube extending axially along the catheter. A junction box housing is located at a distal end of the tube. An elongate body extends distally from the junction box housing. The elongate body is sized and shaped to be ...
The electrode apparatus includes a catheter electrode intravenously positioned within the heart of a patient wherein one electrode, defined by the catheter, is within the right ventricle and a second electrode, defined by the catheter, spaced from the first electrode, is within the superior vena ...
A catheter is used to controllably apply radiant energy in a patient's body, such as in a blood vessel to drill through vascular obstructions. The catheter emits the radiant energy from its distal end in a pattern which defines a relatively small working region in which the energy density ...
发明人: M Maschke 国省代号: DE 摘要: Device for removing a complete vascular occlusion using a CTO catheter, at the distal end of which are disposed stretching tongs and IVUS monitoring, whereby the CTO catheter is combined with an IVUS catheter to form an integrated unit.收藏...
A tissue-removing catheter (10) for removing tissue in a body lumen includes an elongate body (12) sized and shaped to be received in the body lumen. A handle (40) is mounted at a proximal end portion of the catheter (10) and is operable to cause rotation of the elongate body (12)...
A tissue-removing catheter includes an elongate body having proximal and distal end portions and a motor fixed to the distal end portion of the elongate body. A tissue-removing element is mounted on the motor to be driven in rotation by the motor about a drive axis. In some embodiments, th...
