Abstract: An ablation instrument (e.g., an ablation balloon catheter system) includes an elongate catheter having a housing with a window formed therein. An energy emitter is coupled to the elongate catheter and is configured to deliver ablative energy. A controller is received within the window and is coupled to the energy emitter such that axial movement of the controller within the window is translated to axial movement of the energy emitter and rotation of the controller within the window is translated into rotation of the energy emitter. The instrument includes a motor that is at least partially disposed within the housing of the catheter; a first gear that is operatively connected to and driven by the motor; and a second gear that is coupled to the energy emitter and is driven by the first gear to cause rotation of the energy emitter, while allowing the energy emitter to move axially.

A first conduit is provided for delivering the balloon fill media from the source to the balloon catheter for inflation of a balloon of the catheter device. A second conduit is provided for returning the balloon fill media from the balloon catheter to the source for deflating the balloon. A first pump is disposed along one of the first conduit and the second conduit for pumping the balloon fill media through the respective conduits.

Abstract: An ablation catheter that includes a shaft having a distal end and a balloon coupled to the shaft. The balloon has an inner surface and an opposite outer surface. The inner surface has a proximal region including a proximal balloon end, a main center region, and a distal region including a distal balloon end. The ablation catheter also includes an energy emitter disposed inside the balloon and being configured to move both axially and rotationally within the inside of the balloon. The ablation catheter includes a thermally resistant coating disposed along the inner surface of the balloon within at least the main center region of the inner surface of the balloon. The thermally resistant coating is formed of a material selected from a group consisting of: silicone rubber, polyisoprene, polyurethane.

Abstract: Systems and methods for controlling fill media in a balloon catheter are disclosed. The system comprises a catheter having an inflatable balloon, a reservoir for fill media, and a first conduit for delivering fill media from the reservoir to the balloon. The system includes a second conduit for returning fill media from the balloon to the reservoir and a pump configured to circulate fill media through the conduits. The system also includes a valve assembly configured for placement in at least three positions. In the first position, fill media is delivered from the reservoir to the balloon to inflate the balloon. In the second position, fill media is drawn out of the balloon and returned to the reservoir. In the third position, fill media circulates through the conduits between the pump and the balloon and is prevented from flowing back to the reservoir.

Abstract: Automated exception resolution during a software development session based on previous exception encounters is disclosed. A first software development session of a user is monitored. A first exception during the first software development session is detected. In response to detecting the first exception, first contextual information is obtained from the computing device. The first contextual information and first exception information that identifies the first exception is stored in a storage device.
