The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using laser-induced pressure waves created within a sheath to disrupt intimal and medial calcium within the vasculature.

Liquid laser-induced pressure wave emitting catheter sheath

Laser-induced pressure wave emitting catheter sheath

The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using electrically-induced pressure waves created within a sheath to disrupt vascular blockages via the sheath and/or a tip at the end of the sheath.

Electrically-induced pressure wave emitting catheter sheath

The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.

Electrically-induced fluid filled balloon catheter

The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using laser-induced pressure waves to disrupt vascular occlusions. The present disclosure not only provides devices and methods for using laser-induced pressure waves to disrupt vascular occlusions or portions thereof, but the present disclosure also provides devices and methods for disrupting calcium in the media and/or intima layer of an arterial wall.

Laser-induced fluid filled balloon catheter

The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using laser-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using laser-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices and method that use stationary light absorbing material in lieu of and/or in combination of using liquid medium that flows into a balloon for a balloon catheter. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.
