摘要:
An angioplasty balloon catheter and method of making and using the same. The balloon catheter may include a catheter shaft and a balloon coupled to the shaft. The balloon may include one or more cutting edges or member and may include one or more wings. The wings may include an undulating surface.
摘要:
Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.

An angioplasty balloon catheter and method of making and using the same. The balloon catheter may include a catheter shaft and a balloon coupled to the shaft. The balloon may include one or more cutting edges or member and may include a plurality of chambers defined therein.
摘要:
Balloon catheters and methods of making and using the same. A balloon catheter may include a catheter shaft and a balloon coupled thereto. A traction member may be coupled to the balloon catheter adjacent the balloon and may extend along a portion or all of the length of the balloon. The traction member can improve traction between the balloon and a target site.

摘要:
Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Systems include an interface unit with a visual display that provides a visual representation of the geometry of the ablation elements and/or provides selection means for selecting an icon provided on the display.
