    摘要: Apparatus and methods for the treatment of atrial fibrillation are described herein where tissue to be ablated may be monitored under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe may be advanced into the contained region where the tissue may be ablated and monitored for changes in color as well as appropriate positioning.

    摘要: Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

    摘要: Methods and apparatus for obtaining endoluminal access are provided comprising a steerable endoluminal guide having a variable pivot for altering steering dynamics. In one variation, variable pivoting is achieved by advancing a member having a hard or substantially rigid section to various depths within a lumen of the guide. The hard section resists deformation, thereby reducing or precluding pivoting of the guide proximal of the distal-most depth of hard section insertion. In another variation, the guide comprises one or more pivot wires that terminate at a segment of the guide disposed proximal of the guide's distal outlet. In such a variation, the steering pivot of the guide may be altered by applying tension to at least one pivot wire, while concurrently applying tension to a steering wire that terminates more distally than the pivot wire, and that is radially offset from the pivot wire about the circumference of the guide. In another variation, one or more stiffening elements are translated over or alongside one or more steering wires to alter the guide's pivot.
