Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrode assemblies that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Also disclosed are various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

Leadless cardiac stimulation systems

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 is properly positioned by measuring and advancing the system based on a field-of-view of an endoscope or camera disposed within the system.

Systems and methods for treating the prostate

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

Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

Delivery of cardiac stimulation devices

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.

Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

Cardiac stimulation system

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, or denature tissues of the prostate. Methods associated with use of the energy delivery probe are also covered.

Medical devices and methods

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.

A replacement heart valve assembly has a stent frame and a replacement valve. The replacement valve has a plurality of leaflets and a valve frame. The leaflets are attached to the valve frame. Further, the assembly has a plurality of suspension struts attached to the stent frame and the valve frame. The valve frame is suspended within the stent frame via the suspension struts. In some embodiments, the assembly further has a sealing member attached to the stent frame to prevent leakage around the replacement heart valve assembly.
