Abstract

The invention disclosed here generally relates to devices that can modify a property of a nerve. Specifically, the subject invention is contemplated to modify the posterior nasal nerve signal conduction in such a way so as to reduce the signals transmitted to the nasal cavity. Reduction or interruption of the nerve signals results in the reduction of the distal organ activity. In particular, embodiments of the present invention allow for increased lateral contact or apposition of the target tissue region having at least one posterior nasal nerve with the end effector surface by lateral and/or longitudinal translation of the end effector relative to the surgical probe shaft. This improved lateral surface contact has several benefits, including improved patient outcomes and patient safety as the end effector is adequately in contact with target tissue for subsequent ablation therapy.

Dependent claims

A method for treating a tissue region within a nasal cavity of a patient, the method comprising:

inserting a distal end of a surgical probe into the nasal cavity of the patient through a nostril of the patient in a first configuration, wherein the surgical probe comprises an outer shaft, an inner shaft positioned within a lumen of the outer shaft and translatable relative to the outer shaft, and an end effector coupled to a distal end of the inner shaft, wherein, in the first configuration, the inner shaft is in a proximal-most position relative to the outer shaft, wherein the end effector is coupled to the distal end of the inner shaft at a non-zero angle relative to a longitudinal axis of the distal end of the inner shaft in the first configuration, and wherein a distal portion of the inner shaft in the first configuration is substantially aligned with a longitudinal axis of the outer shaft and the end effector is positioned a first distance from a distal end of the outer shaft such that an entirety of the end effector is positioned distal to the lumen of the outer shaft in the first configuration;
advancing the distal end of the surgical probe into the nasal cavity with the surgical probe in the first configuration;
translating the inner shaft relative to the outer shaft so that the surgical probe is deployed to a second configuration, wherein the end effector is translated longitudinally to a second distance greater than the first distance away from the distal end of the outer shaft and laterally away from the longitudinal axis of the outer shaft, wherein the end effector in the second configuration is positioned within proximity of the tissue region having at least one posterior nasal nerve;
and
ablating the at least one posterior nasal nerve of the tissue region with the end effector.

A surgical probe for treating a tissue region within a nasal cavity of a patient, the surgical probe comprising:

an outer shaft having a distal end configured for insertion into a nostril of the nasal cavity of the patient, the outer shaft having a longitudinal axis and a lumen therethrough;
an inner shaft positioned within the lumen of the outer shaft and translatable relative to the outer shaft;
and
an end effector coupled to a distal end of the inner shaft, wherein a distal portion of the inner shaft is substantially aligned with the longitudinal axis of the outer shaft and the end effector is positioned a first distance from the distal end of the outer shaft such that an entirety of the end effector is positioned distal to the lumen of the outer shaft when the surgical probe is in a first configuration during insertion and advancement of the surgical probe into the nasal cavity, wherein, in the first configuration, the inner shaft is in a proximal-most position relative to the outer shaft wherein the end effector is coupled to the distal end of the inner shaft at a non-zero angle relative to a longitudinal axis of the distal end of the inner shaft in the first configuration, and wherein a translation of the inner shaft relative to the outer shaft configures the end effector longitudinally to a second distance greater than the first distance away from the distal end of the outer shaft and laterally away from the longitudinal axis of the outer shaft when the surgical probe is in a second configuration, wherein the end effector in the second configuration is in lateral contact with the tissue region having at least one posterior nasal nerve and is configured to ablate the at least one posterior nasal nerve.
