| 20080215046 | MEDICAL DEVICE CONTROL SYSTEM - A medical device for use by an operator to perform a medical procedure in a body includes a handle to be held by the operator, a shaft attached to the handle and an actuating assembly to control functions associated with the medical procedure. The shaft includes an operative distal portion to perform a medical procedure in the body. The medical device may be part of an ablation catheter system that is programmed to correlate one or more functions with the actuation of the actuating assembly. Multiple actuating assemblies may be provided. Each actuating assembly may be a button. Other types of actuating assemblies may also be used, such as switches or a trackball. The actuating assembly may also be provided on a sleeve that may be selectively attached to the handle of the catheter or the physician operating the catheter, for example. | 09-04-2008 |
| 20090182316 | LINEAR ABLATION DEVICES AND METHODS OF USE - Described herein are various methods and devices for delivering cryoablative therapy. Various ablative patterns can be produced by the devices, including, linear ablation patterns. One exemplary device includes a cryoablation chamber and a volume displacement chamber. In use, the volume displacement chamber can be expanded to support the cryoablation chamber. | 07-16-2009 |
| 20090182317 | ABLATION DEVICES AND METHODS OF USE - Described herein are various methods and devices for delivering cryoablative therapy. One such device includes a cryoablation chamber and a volume displacement chamber. In use, the volume displacement chamber can be expanded to occupy a non-therapeutic volume. | 07-16-2009 |
| 20090287202 | APPARATUS AND METHODS FOR CRYOGENICALLY ABLATING TISSUE AND ADJUSTING CRYOGENIC ABLATION REGIONS - Apparatus and methods for performing cryogenic ablation of tissue and adjusting the size and/or location of a cryogenic cooling region. A cooling assembly may include tubes for dispensing and exhausting a coolant or refrigerant. One or both of the tubes may be moved, e.g., slidably adjusted, in order to adjust the location or size of a cryogenic ablation region. The cooling assembly may be integrated into cryogenic ablation devices including a cryogenic balloon device that includes an inner inflatable balloon and another balloon that is at least partially wrapped around the inner balloon and carries refrigerant for performing cryo-ablation. Electrodes permit electrical mapping of tissue before or after cryo-ablation to verify success of the procedure. | 11-19-2009 |
| 20100204691 | INSULATED ABLATION CATHETER DEVICES AND METHODS OF USE - Disclosed herein is a catheter device sized and shaped for vascular access that has an elongate body extending between a proximal end and a distal end. Further, the elongate body has at least one inner lumen configured to receive a fluid. The catheter also has an ablation electrode configured to provide ablative energy, wherein the electrode is located distally along the elongate body and includes a passageway fluidly connected to the lumen of the elongate body. Also, the catheter has a sensor configured to provide a signal representative of temperature, and an insulating chamber extending at least partially about the ablation electrode and configured to at least partially insulate the sensor. | 08-12-2010 |
