What changed
Medtronic Vascular, Inc. received US Patent 12605184B2 from the USPTO for a tissue-removing catheter system. The invention includes an elongate drive member, a tissue-removing element at the distal end, an inner liner with a guidewire passage, and a distal tip extending beyond the tissue-removing element without direct connection to the liner.
For competitors in the vascular device space, this patent establishes IP protection around Medtronic's catheter design with a non-connected distal tip configuration. Companies developing similar tissue-removal catheters should review this patent landscape to assess design freedom and potential licensing considerations.

Abstract
A tissue-removing catheter for removing tissue in a body lumen includes an elongate drive member and a tissue-removing element operatively coupled to the distal end portion of the elongate drive member. An inner liner received within the drive coil defines a liner passage sized and shaped to receive a guidewire therein. A distal tip extends distally outward from the tissue-removing element. The distal tip has a proximal end portion disposed within the tissue-removing element and a distal end portion spaced distally from the tissue-removing element. A distal end portion of the inner liner is axially spaced apart from the proximal end portion of the distal tip such that the distal tip is free from direct connection to the inner liner.
