Abstract:

A surgical instrument may include a multi-lumen catheter configured to be inserted within the tissue. The multi-lumen catheter may include a first lumen that may enable a flow of a fluid, a second lumen that may receive a navigation probe that may facilitate an ability to locate the region of interest within the tissue, and an expandable membrane that may be situated toward a distal end of the first lumen to form an expandable cavity. The expandable cavity may be configured to expand or contract based on the flow of the fluid through the first lumen. The surgical instrument may include a fluid line, coupled to the first lumen, that may supply the fluid to the first lumen to enable the expandable cavity to expand or withdraw the fluid from the first lumen to enable the expandable cavity to contract.
