Abstract
The present technology is directed generally to devices, systems, and methods for capturing and cutting fibrous and trabeculated structures (such as synechiae) in vessel lumens. In one embodiment, the present technology includes an intraluminal tissue modifying system configured to capture the fibrous structures, put the fibrous structures in tension, and controllably cut through the fibrous structures without applying appreciable additional force to the vessel wall. The system may include an expandable capture device and a cutting device.
Claims16
A device for modifying intraluminal tissue, the device comprising:
- an outer shaft having a proximal portion and a distal portion, the outer shaft defining a lumen extending between the proximal portion and the distal portion, wherein the outer shaft includes a plurality of slots extending along a length of the distal portion, and wherein the portions of the outer shaft between the slots define capture members, each of the capture members including a distal joint at its distal terminus, a proximal joint at its proximal terminus, and an intermediate joint positioned along its length between the distal and proximal joints;
- and
- an inner shaft disposed within the lumen, wherein a distal end region of the inner shaft is fixed to a distal end region of the outer shaft such that proximal movement of the inner shaft with respect to the outer shaft pulls distal portions of the capture members proximally and forces the capture members to bend outwardly away from the longitudinal axis of the outer shaft,
- wherein each of the capture members, when deployed, include a generally curved distal segment extending between its distal joint and its intermediate joint, and a generally curved, concave proximal segment extending between its intermediate joint and its proximal joint.

- wherein
- at least one of the capture members, when deployed, includes a generally curved proximal segment extending between its intermediate joint and its proximal joint,
- at least one of the proximal segments includes an elongated opening extending along at least a portion of its length, and
- when the cutting device is in a deployed state, the cutting element extends outwardly away from the central longitudinal axis of the inner shaft through the opening in the respective proximal segment.
