    摘要： A curved ablation catheter imparts ablative energy to target tissue, for example, along a trabecular slope, e.g., in the right atrium along the isthmus between the ostium of the inferior vena cava and the tricuspid valve. The catheter is formed with a preset curvature that, when deployed, both translates linearly and increases in radius to aid in the formation of spot or continuous linear lesions. A method of treating atrial flutter employs the curved ablation catheter.

    摘要： An introducer sheath has multiple distal slots allowing for translation of a catheter within a cardiac cavity. A pair of longitudinal slots are provided on opposite sides of the sheath near the distal end. A portion of the catheter may deploy from one of the slots while the ablation tip deploys from the opposing slot. The sheath design provides greater maneuverability for the catheter in a direction orthogonal to the tissue to be ablated, while restricting lateral movement of the catheter. The longitudinal direction of the slots further aids in the formation of linear lesions using the catheter.

    摘要： A spring-tip, flexible electrode, and a method for using that electrode for tissue ablation, are disclosed. The spring-tip, flexible electrode comprises an enshrouded flexible electrode (e.g., an enshrouded plurality of flexible brush filaments or bristles) for applying ablative energy (e.g., RF energy) to target tissue during the formation of spot or continuous linear lesions. The spring of the spring tip may comprise compressible coils, compressible mesh, or compressible bellows, among other things. The spring provides axial suspension and is capable of axial compression and extension, and is flexible enough for deflection and bending. The axial suspension of the spring tip facilitates the desired contact between the electrode and the tissue surface. A shielded, spring-tip, flexible electrode is also disclosed, and includes a flexible nipple or shield. The spring-tip, flexible electrode facilitates enhanced tissue contact in difficult environments (e.g., during ablation of a contoured or trabeculated surface inside a beating heart) since the flexible electrode readily conforms to surface contours while the bending stress of the spring enhances the contract pressure on the tissue.

    摘要： The instant invention is directed toward an ablation catheter and sheath incorporating wire rail system. The catheter may have a combination of rigid and flexible components to orient an ablation electrode at the distal tip toward the target tissue. The wire rail acts to guide an ablation tip along the tissue to aid in the formation of spot or continuous linear lesions on a trabecular surface, e.g., in the right atrium along the isthmus between the ostium of the inferior vena cava and the tricuspid valve.

    摘要： A brush electrode and a method for using the brush electrode for tissue ablation are disclosed. The brush electrode comprises a plurality of flexible filaments or bristles for applying ablative energy (e.g., RF energy) to target tissue during the formation of spot or continuous linear lesions. Interstitial spaces are defined among the filaments of the brush electrode, and the interstitial spaces are adapted to direct conductive or nonconductive fluid, when present, toward the distal ends of the brush filaments. The brush electrode facilitates electrode-tissue contact in target tissue having flat or contoured surfaces. The flexible filaments may be selectively trimmed to give a desired tip configuration or a desired standoff distance between the tissue and the conductive filaments in the brush electrode. Also, the filaments may be grouped into clusters. A shielded-tip brush electrode, including a flexible boot, is also disclosed.
