Apparatuses, systems, and methods for conveying implements through a narrow passage in a body

A system comprising:

• an electrical power source having poles across which an electrical current is selectively applied;
• an imaging device configured to receive an output of an imaging sensor and display imaging data collected by the imaging sensor;
• an insertion tube defining therein a pair of lumens, the insertion tube being configured to slide through a bodily orifice and into a bodily passageway to a target tissue;
• a first probe electrically connectable to a first pole of an electrical power source, the first probe being slidably receivable through a first lumen of the pair of lumens and having a distal end insertable into the target tissue, wherein the first probe and the first lumen are configured to enable extension of the first probe into the target tissue and anchoring of a distal end of the insertion tube adjacent the target tissue upon deployment of the first probe;
• an imaging probe electrically connectable to the imaging device configured to collect imaging data at a distal end, the imaging probe being further configured to be slidable through a second lumen of the pair of lumens and positionable to collect imaging data at a distal end of the insertion tube to guide insertion of the first probe into the target tissue;
• a second probe electrically connectable to a second pole of the electrical power source, the second probe being slidably receivable through the second lumen in exchange for the elongated imaging probe subsequent to removal of the imaging probe from the second lumen, the second probe having a distal end insertable into tissue adjacent the first probe anchored in the target tissue to apply a treatment in conjunction with the first probe;
• wherein the first and second probes are configured to perform ablation.

A method comprising:

• inserting an insertion tube into a bodily orifice and through a bodily passageway to a target tissue, the insertion tube defining therein a pair of lumens configured to simultaneously receive at least two of a first electrically-conductive elongated probe (first probe),
• a second electrically-conductive elongated probe (second probe), and an elongated imaging probe (imaging probe);
• positioning a distal end of the insertion tube proximate a target tissue;
• sliding the imaging probe through one of the pair of lumens;
• collecting imaging data with the imaging probe to verify a position of a distal end of the insertion tube proximate the target tissue;
• sliding the first probe through one of the pair of lumens not receiving the imaging probe to insert a distal end of the first probe into the target tissue;
• anchoring the first probe in the target tissue to secure a position of the distal end of the insertion tube adjacent the target tissue;
• collecting imaging data with the imaging probe to verify insertion of the first probe into the target tissue;
• after collecting the imaging data to verify the insertion of the distal end of the first probe into the target tissue, replacing the imaging probe in the one of the pair of lumens with the second probe by sliding the second probe into the one of the pair of lumens not receiving the first probe to insert a distal end of the second probe into tissue adjacent the first probe anchored in the target tissue;
• and
• electrically connecting proximal ends of the first and second probes to an electrical power source so that an electrical current is applied to the target tissue between the distal ends of the first probe and the second probe;
• wherein the first and second probes are configured to perform ablation.
