Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a catheter, an expansion member coupled with a distal portion of the catheter, an ablation structure including one or more longitudinal electrode segments, and an ablation structure support coupled to the ablation structure configured to at least partially unfurl as the expansion member expands and furl as the expansion member contracts. The ablation structure may include multiple separately wired and/or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. In some instances, one or more springs are coupled to the ablation structure configured to promote unfurl or furl around the expansion member. In some instances, one or more protection elements are be positioned along the catheter.

Unfurling electrode devices

Methods, apparatuses, and systems are described for minimizing various leakage effects of multi-zone ablation devices. Apparatuses may include an ablation device for treatment of tissue including an ablation structure with a plurality of bipolar electrode zones. Each of the zones may include an in-zone channel pair comprising a positive channel and a negative channel. The ablation structure may be configured such that, for any adjacent electrode zone pair comprising a first electrode zone and a second electrode zone adjacent to the first electrode zone, the positive channel of the first electrode zone is electrically distinct from the positive channel of the second electrode zone, and the negative channel of the first electrode zone is electrically distinct from the negative channel of the second electrode zone. Moreover, the ablation structure may be arranged such that a total number of electrically distinct channels that is less than twice a total number of the plurality of electrode zones.

Methods, apparatuses and systems are described for preventing the over-tightening of a furled ablation structure support around an expandable member. An ablation device for treatment of tissue in body lumens with varying sizes is disclosed. The ablation device may include a catheter, an expansion member coupled with a distal portion of the catheter, and an ablation structure support configured to at least partially unfurl or furl around the expansion member as the expansion member expands or contracts. The ablation device may further include a spacer coupled with the catheter and configured to limit a minimum diameter of the ablation structure support when the expansion member is completely contracted.

Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.

Implant system for controlling airway passage

An airway implant device for maintaining and/or creating an opening in air passageways is disclosed. Methods and devices for removing, the device are also disclosed. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

Methods and devices for removal of a tongue stabilization device

An airway implant device for maintaining and/or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The implant is an implant for stabilizing the tongue, the implant having an anchoring portion for securing a first end of the implant with the mandibula; a control portion connected with the anchoring portion, configured for selectively activating the implant; a flexible portion connected at its proximal end with the control portion, where the flexible portion has three-dimensional flexibility in a first state and where the flexible portion has a lesser three-dimensional flexibility in a second state, and where the flexible portion is selectively switchable between the first and second state by the control portion; an anchoring portion for connecting the implant with the base of the tongue connected with the flexible portion, and a latch mechanism coupled with the control portion and configured to maintain the flexible portion in either of the first and second states. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.
