Abstract:
The present invention provides an electrical block implant sized and shaped for securement at the perimeter of the pulmonary ostium of the left atrium. By utilizing various expandable ring designs and optional anchoring mechanisms, the present invention causes even, circular scarring around the perimeter of the pulmonary ostium, achieving reliable blocking of aberrant electrical signals responsible for atrial fibrillation.
Abstract:
The present invention provides a mechanical injury device having cutting elements for injuring tissue and thereby creating electrical block that can prevent atrial fibrillation. These cutting elements may preferably be removable, breakaway, or simply integral to the injury device and may be delivered, for example, by catheter or hand tool.

Abstract:
The present invention provides positioning mechanisms for devices that cause conduction blocks or ablation in desired areas of tissue. The positioning mechanisms allow for variable geometry of the target sites and enable more accurate therapy at the tissue site.
Abstract:
The present invention seeks to provide an implant configured to utilize at least two different scar-generating mechanisms that are generated in sequential or overlapping stages. For example, in one embodiment the present invention provides an expandable device that can be positioned at a desired target location within a patient to generate mechanical ablation damage. After a predetermined amount of mechanical ablation has occurred, additional ablation damage is generated by a different source, such as energy delivery, drug delivery, or inflammatory material delivery. In this respect, the overall ablation scarring can be better controlled by utilizing the ablation techniques that are most appropriate at specific phases of a technique or locations within a patient.
Abstract:
In one embodiment, the present invention provides a bipolar ablation device with multiple needle electrodes that penetrate a desired target tissue. These electrodes may be arranged in a variety of therapeutically effective arrangements, such as a comb-like shape, a multi-needle wheel, or an expanding bow design. By contacting and preferably penetrating the cardiac tissue with bipolar electrodes, a user can more precisely create ablation-induced scarring and thus electrical block at desired target locations without causing unwanted damage and related complications.
