Methods and devices are provided for determining anatomical distance and/or position measurements during an endoscopic procedure. Markings are placed either physically or superimposed on a distal end of an elongate tool, such that the markings are viewable in an imaging field of view of the endoscope. Anatomic distances may be determined by measurements performed with the tool. The size and/or position of anatomical structures or unknown objects may also be determined using the marked tool.

Measurement markings in distal tip imaging field of view

A vapor delivery system and method is provided that is adapted for treating prostate tissue. The vapor delivery system includes a vapor delivery needle configured to deliver condensable vapor energy to tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the prostate tissue. The vapor delivery system includes a generator unit and an inductive heating system to produce a high quality vapor for delivery to tissue. Methods of use are also provided.

Vapor ablation systems and methods

An endoscopic device includes a flexible shaft extending distally from a handle which, during use remains outside a living body, the shaft comprising a pull wire extending therethrough from the handle and a distal tip rotatably coupled to a distal end of the shaft, the distal tip comprising an imager directed distally from a distal face of the distal tip, the imager including a chip and a lens, a distal end of the pull wire being coupled to the distal tip in combination with an actuation mechanism coupled to a proximal end of the pull wire so that, actuation of the actuation mechanism, pulls the pull wire proximally through the shaft rotating the distal tip relative to the shaft to alter a field of view of the imager.

Disposable endoscopic device

A vapor delivery device is provided that may include any of a number of features. One feature of the vapor delivery device is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate tissues of the prostate. The vapor delivery device can include a handle portion and a cartridge portion. The cartridge portion can be configured to be inserted into a lumen of the handle portion to align and position a vapor coil of the cartridge portion within a RF coil of the handle portion. Methods associated with use of the energy delivery probe are also covered.

A needle adjustment device is provided. The needle adjustment device includes a stopping component and an actuator. The stopping component is configured to establish a maximum penetration depth of a needle. The actuator is fixedly coupled to the needle and movable proximally and distally to one or more positions and to adjust a penetration depth of the needle depth up to the maximum penetration depth.

Systems and methods for controlling needle penetration

A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, denaturate the prostate. In some embodiments, the vapor delivery needle can be advanced a predetermined distance into the prostate with a solenoid actuation mechanism. Methods associated with use of the energy delivery probe are also covered.

A vapor delivery system and method is provided that includes a number of features. In one embodiment, a method comprises inserting a vapor delivery needle into tissue of a patient, activating a flow of vapor from a vapor generator through vapor delivery ports of the vapor delivery needle to cause condensed liquid to exit vapor delivery ports of the vapor delivery needle, generating vapor in the vapor generator, delivering a dose of vapor through the vapor delivery ports of the vapor delivery needle into the tissue, and after the dose of vapor is delivered, re-activating the flow of vapor from the vapor generator through the vapor delivery ports of the vapor delivery needle to prevent a vacuum from forming in the vapor delivery needle. Vapor therapy systems are also provided.
