Abstract
A tissue-removing catheter for removing tissue from a body lumen includes an elongate catheter body configured for insertion into the body lumen and a tissue-removing element. A side opening in the distal portion of the catheter body is defined by opposite first and second side edges, a proximal edge extending between the first and second side edges, and a distal edge opposite the proximal edge and extending between the first and second side edges. The side opening window has a longitudinal axis extending between the distal and proximal edges. The tissue-removing element is configured to move between a tissue-removing position, in which the tissue-removing element is exposed through the side opening window, and a neutral position, in which the tissue-removing element is positioned inside the distal portion of the catheter. The distal edge is asymmetric about the longitudinal axis of the side opening window.
