An aspect of various embodiments of the present invention system and method provide, but not limited thereto, a novel means for epicardial ablation using a double-curve steerable sheath and a double-curve deflectable open irrigated-tip/suction catheter that can be guided around the apex of the heart and adjusted so as to position the distal tip optimally. The catheter can also both deliver fluid to and withdraw fluid from the pericardial space. Access to the epicardial surface of the heart is via a subxiphoid entry. The method and means presented include, but are not limited to, steering, energy delivery, bipolar mapping, placement and use of electrodes, irrigation, suction of irrigation fluid, and other details of the subject invention.

Fluid cooled optical fibers are disclosed. An exemplary fiber comprises a fiber body including a distal end, an inner cap surrounding said distal end, an outer cap surrounding said inner cap, and a tube attached to said outer cap. The tube and outer cap may define a first flow channel, the outer and inner caps may define a second flow channel, and the outer cap may including one or openings for placing the first flow channel in communication with the second flow channel. Associated systems also are disclosed.

A surgical device is disclosed that comprises a shaft member and a pair of electrodes. The shaft member has a pair of electrode channels that open at the distal end of the shaft member, wherein the electrode channels are positioned adjacent to one another. The pair of electrodes are configured to deliver energy, and one of the pair of electrodes are configured to be disposed in each electrode channel such that distal ends of each of the electrodes are arranged to protrude from the distal end of the shaft member. The shaft member further includes at least one lumen opening at the distal end of the shaft member.

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.

A non-puncturing microwave ablation antenna, including an irradiator located at a front end of the antenna and an irradiator cover sleeved on the irradiator, where a front end of the irradiator cover is blunt. Because the front end of the irradiator cover is designed to be blunt, the special non-puncturing appearance of the irradiator cover enables the antenna to freely penetrate inside the lung tissue without puncturing blood vessels and bronchi in the lungs. In addition, blood vessels of tumor existing in the Ground-Glass Opacity (GGO) would not be damaged by the blunt head and bleed, thereby reducing a rate of surgery failure caused by that a lesion cannot be identified because of bleeding inside the lung, and in addition, avoiding a possibility that tumor cells spread through a puncturing passage or bleeding blood vessels.

Devices for therapeutic nasal neuromodulation and associated systems and methods are disclosed herein. A system for therapeutic neuromodulation in a nasal region configured in accordance with embodiments of the present technology can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.
