Devices, systems, and methods for removing targeted lesions from vessels

摘要

Devices, systems, and methods for removing targeted lesions from vessels. In at least one embodiment of a device for removing a stenotic lesion from a vessel, the device comprises a sizing portion capable of measuring a luminal size parameter when at least part of the device is positioned within a lumen of a luminal organ, a typing portion, wherein at least part of the at least one typing portion is capable of physically touching a portion of the luminal organ or a structure therein, and a treatment portion capable of removing at least part of a stenotic lesion from the luminal organ.

主权项

1. A device for insertion within a luminal organ, comprising:
an elongated body having a distal body end, a fixed portion, and a rotatable portion at or near the distal body end; at least one directional sensor positioned on the rotatable portion of the elongated body, the at least one directional sensor configured for axial rotation relative to and distinct from the fixed portion of the elongated body and operable to obtain a measurement from the luminal organ or a structure therein, wherein the measurement is indicative of less than an entire circumference of the luminal organ; and at least one treatment portion capable of removing at least part of a stenotic lesion from a luminal organ; and an extension apparatus coupled to the at least one directional sensor, the extension apparatus capable of moving the at least one directional sensor radially relative a longitudinal axis of the elongated body between a first position and an extended second position.
