摘要： Catheters are presented herein having planar end effectors of various configurations, generally providing a two-sided and multi-layered platform for electrodes and sensors. In some examples, the end effector has a support frame (e.g. nitinol) between a pair of flexible circuits. The end effector can also include a polymer (e.g. silicone, LCP, etc.) between the flexible circuits and encapsulating the support frame. This platform facilitates positioning of electrodes on either side (including both sides) of the end effector in a variety of spacings and facilitates ultra-tight electrode spacing and/or a large area electrode. Sensors (ultrasound transducers, navigation coils, etc.) can be layered within the end effector between outer surfaces of the flexible circuits in a variety of configurations.

摘要： This disclosure is directed to a catheter having a dual node multiray electrode assembly at the distal end of the catheter body. The dual node multiray electrode assembly includes a proximal multiray array with a plurality of spines connected at one end, each spine having at least one ablation electrode, and a distal node. The dual node multiray electrode assembly may have an expanded configuration and a collapsed configuration wherein the spines are arranged generally along a longitudinal axis of the catheter body. The distal node may be configured to be deployed within a vessel and the proximal multiray array may be configured to engage tissue forming an ostium of the vessel with the ablation electrodes. In some embodiments, the relative distance between the proximal multiray array and the distal node is adjustable.

摘要： The disclosed technology includes a medical probe comprising a plurality of spine members that form a substantially cylindrical structure. Each spine is stamped from a continuous piece of flat stock and heat-treated to a configuration including a first section extending along a longitudinal axis from a first end to a first bend, a second section extending from the first section curvilinearly with respect to the longitudinal axis and comprising a bifurcation point, and a third section extending along the longitudinal axis from a second bend to a second end so that a proximal portion of the third section is generally parallel to the first section. The second section comprises a continuous leg and a discontinuous leg. The continuous leg extends between the first section and the bifurcation point. The discontinuous leg extends towards the first section and terminates at a termination point between the bifurcation point and the first end.

摘要： The disclosed technology includes basket catheters comprising a generally cylindrical structure having electrodes attached thereto. The disclosed technology can include a structural unit for an end effector comprising a proximal member extending along a longitudinal axis. The proximal member can define a plurality of divergent curvilinear members. Each divergent curvilinear member can define two meander members extending along the longitudinal axis such that the structural unit comprises a plurality of meander members. Each of the plurality of meander members can be connected to a respective convergent curvilinear member of a plurality of convergent curvilinear members. The structural unit can further comprise a distal member connected to the plurality of convergent curvilinear members.

摘要： A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode matrix having a plurality of spines arranged in parallel configuration on which a multitude of electrodes are carried in a grid formation for providing uniformity and predictability in electrode placement on the tissue surface. The matrix can be dragged against the tissue surface upon deflection (and/or release of the deflection) of the catheter. The spines generally maintain their parallel configuration and the multitude of electrodes generally maintain their predetermined relative spacing in the grid formation as the matrix is dragged across the tissue surface in providing very high density mapping signals. The spines may have free distal ends, or distal ends that are joined to form loops for maintaining the spines in parallel configuration.
