Flexible high-density mapping catheter tips and flexible ablation catheter tips with onboard high-density mapping electrodes |
摘要 |
Flexible high-density mapping catheter tips (10A) and flexible ablation catheter tips with onboard high-density mapping electrodes (18) are disclosed. These tips can be used for diagnosing and treating cardiac arrhythmias. The flexible, distal tips are adapted to conform to tissue and comprise a plurality of microelectrodes mounted to permit relative movement among at least some of the microelectrodes. The flexible tip portions may comprise a flexible framework forming a flexible array of microelectrodes (for example, a planar or cylindrical array) adapted to conform to tissue and constructed at least in part from nonconductive material in some embodiments. The flexible array of microelectrodes may be formed from a plurality of rows of longitudinally-aligned microelectrodes (18). The flexible array may further comprise, for example, a plurality of electrode-carrying arms or electrode-carrier bands. Multiple flexible frameworks may be present on a single device. A delivery adapter having an internal compression cone is also disclosed. |

1. A catheter comprising the following:
an elongated catheter body comprising a proximal end and a distal end, and defining a catheter longitudinal axis extending between the proximal and distal ends; and a flexible, distal tip assembly at the distal end of the catheter body and adapted to conform to tissue, the flexible distal tip assembly comprising a plurality of microelectrodes mounted so that at least some of the microelectrodes are moveable relative to other of the microelectrodes. |
