FLEXIBLE CIRCUIT FOR DELIVERY THROUGH A WORKING CHANNEL

摘要

Methods, systems, and devices for providing treatment to a target site are described. The system may include a guide assembly, an expandable support device coupled with the distal end of the guide assembly, and an operative member disposed on the expandable support device. The expandable support device may be configured to transition between a collapsed and expanded configuration. The expandable support device may be supported by one or more flexible supports aligned in parallel with an axis about which the expandable support device collapses and/or multiple splines arranged in a pattern configured to promote transitioning of the expandable support device between an expanded and collapsed configuration. The guide assembly may be configured to provide torque to the expandable support device. The operative member can include multiple electrodes arranged in parallel to the axis about which the expandable support device collapses.
