A system for delivering mechanical waves to treat a lesion present in a vessel of a body, including an external mechanical wave source for generating mechanical waves from outside of the body, and a wave directing device insertable in the vessel, the wave directing device configured to receive the mechanical waves generated by the external mechanical wave source and to redirect the mechanical waves according to a target direction.

Combined non-invasive and minimally invasive mechanical energy targeting

The present invention provides a medical system, including a catheter defining an injection lumen, a chamber in fluid communication with the injection lumen, and an exhaust lumen in fluid communication with the chamber; a first temperature sensor positioned in the exhaust lumen proximal to the chamber; a second temperature sensor positioned in the chamber; and a console in electrical communication with the first and second temperature sensors, the controller modifying coolant flow through the medical device based at least in part upon a signal received from the first and second temperature sensor. The system may further include a thermally-conductive element circumscribing a substantial portion of the exhaust lumen proximal to the chamber, where the first temperature sensor is mounted to the thermally-conductive element, and the thermally-conductive element may include at least one of a braid, coil, and band.

Thermocouple-controlled catheter cooling system

The present invention provides a medical device that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.

Variable geometry cooling chamber

A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.

Method and apparatus for inflating and deflating balloon catheters

A catheter device and method for treating an artery with thrombus, the catheter comprising an inflatable member. A carrier catheter has a proximal end and a distal end adapted to be inserted percutaneously into an artery, the carrier catheter having a tubular body adjacent to a rear end of the inflatable member. An inflating tube passes through the tubular body and having an open front end in fluid communication with the inflatable member to inflate same. An infusion tube is adapted to infuse pharmacologic agents, the infusion tube passing through the tubular body and having an open front end extending beyond the inflatable member. An aspiration tube is adapted to aspire the thrombus, the aspiration tube passing through the tubular body and having an open front end between the carrier catheter and the inflatable member.

Method and device for infusion of pharmacologic agents and thrombus aspiration in artery

A device for delivering mechanical waves to treat a lesion present in a blood vessel, including a catheter extending between a first proximal end and a first distal end, an inflatable balloon secured to the catheter and being adjustable between an inflated configuration and a deflated configuration, and at least one mechanical waveguide extending between a second proximal end and a second distal end for propagating at least one mechanical wave from the second proximal end to the second distal, with the mechanical waveguide being secured to the inflatable balloon or the catheter.

Device for delivering mechanical waves through a balloon catheter

The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. A check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. Additionally, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.

Fluid control system for a medical device

A medical device includes a steering element defining a passage for a guide wire. A fluid injection tube defining a proximal and a distal end is also included, wherein a portion of the fluid injection tube is contoured about a portion of the steering element. A plurality of injection ports may be disposed in the portion of the fluid injection tube contoured about the steering element.
