An ablation apparatus for creating a lesion in target tissue, the ablation apparatus having an ablation shaft including a handle, a first portion, an ablation portion, distal tip, at least one ablation energy delivery lumen, at least one ablation energy return lumen, and a stylet lumen that extends substantially along a length of the ablation shaft from the handle to at least the ablation portion. The ablation apparatus also includes a stylet that is capable of being inserted into the stylet lumen where the stylet is made of a shape-memory material.

Methods, devices, and systems for treatment and removal of skin lesions, such as skin tags, are disclosed herein. In at least one embodiment, a system for treating a skin lesion comprises: a tweezer comprising a treatment region; and an activation station, the activation station configured with a first receiving end and a second receiving end. In at least one embodiment, the activation station receives the tweezer at the first receiving end, and receives a cryogenic agent at the second receiving end. The first receiving end is fluidly coupled to the second receiving end to facilitate delivery of the cryogenic agent to the treatment region of the tweezer.

A system and method of use thereof are disclosed, the system including a treatment source, such as an electrosurgical generator and a plurality of treatment devices operable to be coupled to the treatment source, one or more of the treatment devices being associated with one or more device identifiers which can be, for example, physically present on the device or contained in device software.

The disclosure relates to a path planning device for multi-probe joint cryoablation, the device comprising a memory and a processor. The memory stores a computer program, and the processor, when executing the computer program, implements the following steps: acquiring a target region in a medical scanned image of a target object and corresponding to a target tissue to be cryoablated;

selecting a single-probe ablation region from the target region; for the single-probe ablation region, obtaining a puncture path of single-probe cryoablation and a corresponding ice ball coverage region; and if the ice ball coverage region does not completely cover target region, then taking the remaining region of the target region from which the ice ball coverage region is excluded as a new target region, and returning to the step of selecting the selecting the single-probe ablation region from the target region.

A system and device for cryoablation of tissue that is suitable for use within an MRI environment. The device may include an elongate body, a treatment element at the distal portion of the elongate body, and one or more pull fibers. The pull fibers may be composed of a non-ferromagnetic material, such as a polymer. Likewise, none of the other device components may be composed of a ferromagnetic material. The device may also include at least one fiber optic sensor. The elongate body distal portion may include a distal tip to which the pull fibers are directly coupled. Additionally or alternatively, the elongate body may include one or more pull fiber lumens configured to allow the pull fibers to deflect the distal portion when a pull force is exerted on the pull fibers.
