摘要： A catheter is designed with a virtual electrode structure for creating a linear lesion. The catheter includes a sensor array that measures temperatures of adjacent tissue along the length of the virtual electrode section. The sensors in the sensor array include a conductive material that is substantially coated with an electrically and thermally insulating material. An aperture is formed in the insulating coating to expose an area of the conductive material. Leads are coupled with each sensor and are connected at their opposite, proximal ends with a discrimination circuit. The circuit processes the signals induced in the sensors to output a single temperature measurement, for example, the highest temperature, the lowest temperature, or the average temperature. The sensors also measure cardiac electrical activity and the leads are further connected to an electrocardiograph monitor to determine the efficacy of treatment.

摘要： A magnetically-guided catheter includes a tip positioning magnet in the distal end portion thereof configured to interact with externally applied magnetic fields for magnetically-guided movement. The magnet may be geometrically asymmetric, for example, a C-shape in radial cross-section, so as to allow side-loading of an irrigation fluid lumen and other wire(s) or lines during fabrication. The outer shaft includes a plurality of segments, including a generally soft segment at the distal end thereof for magnetically-guided navigation. The fluid lumen, which extends through the outer shaft, and further extends completely through the magnet for coupling to the ablation electrode irrigation fluid inlet, is constructed so that its mechanical properties (i.e., flexibility) substantially matches that of the outer shaft. The combination of the outer shaft, inner fluid lumen and positioning magnet has interoperability with a broad range of ablation tip assemblies.

摘要： A tissue puncture assembly includes an elongate tubular member having a lumen, a distal portion having a side wall, a side port opening extending through the side wall and, and a guiding surface having a distal end that extends adjacent to a distal edge of the side port opening. The tissue puncture assembly further includes a flexible puncture member insertable through the lumen of the elongate tubular member. The flexible puncture member deflects upon contacting the guiding surface to exit the elongate tubular member through the side port in a lateral direction relative to a longitudinal direction of the elongate tubular member. The tissue puncture member is capable of puncturing tissue at an oblique angle. The tissue puncture member may further adopt a pre-formed shape at its distal end to prevent inadvertent puncture of tissue and to maintain access to the puncture site. The transseptal puncture assembly may include various sensors to identify tissue structures and precisely locate the desired puncture site.
