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 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.

An implant delivery system and method comprises an implant, for example, a stent, and a delivery catheter. The stent has a scaffold with a coating or a shell that retains the scaffold in a collapsed configuration. The coating or shell is made of a material that dissolves or biodegrades upon exposure to a dissolution or biodegradation media. The stent is used with an implant delivery system which has a catheter with a catheter, wherein the stent is mounted on the catheter shaft. The catheter shaft is configured to be withdrawn through the patient's vessel when the scaffold is in its expanded configuration. Advantageously, the implant is thereby prevented from changing length during implant delivery and implant deployment.

A bulbous valvuloplasty balloon is described that maintains its bulbous shape in its final deployed configuration along with the method of use for post dilation of a TAVR device. The bulbous balloon has two larger diameter bulb segments located on each side of a smaller diameter waist and can be used to post dilate a TAVR device that has been implanted at the site of a stenotic aortic valve. The post dilation causes deformation of the underlying tissues residing outside of the TARV stent structure.

An aortic occluder catheter with expandable balloons for increasing cerebral blood blow has one or more balloons on a catheter shaft. To assist the balloon in bearing up against arterial blood flow while positioned retrograde in the aorta, the balloon is bonded to the catheter shaft in tension.
