Systems and methods for cylindrical cage mapping and ablation catheters having integrated electrodes

An end effector for a medical probe comprising:

• a plurality of structural members connected to each other and forming a generally cylindrical structure, the generally cylindrical structure comprising a circumferential surface portion extending around a longitudinal axis and a substantially planar distal portion perpendicular to the longitudinal axis, each structural member of the plurality of structural members comprising:
• a proximal member extending along a longitudinal axis, the proximal member defining a plurality of divergent curvilinear members;
• each divergent curvilinear member defining two meander members extending along the longitudinal axis such that the structural member comprises a plurality of meander members, each of the plurality of meander members being connected to a respective convergent curvilinear member of a plurality of convergent curvilinear members;
• and
• a distal member connected to the plurality of convergent curvilinear members.

A method of constructing a medical probe, the method comprising:

• forming a plurality of spines from a planar sheet of material;
• forming a plurality of electrodes on the planar sheet of material by vacuum deposition;
• forming a plurality of electrical traces on the planar sheet of material, each electrical trace of the plurality of electrical traces being connected to a respective electrode of the plurality of electrodes;
• and
• connecting opposite ends of the planar sheet of material to each other to form a cylindrical structure comprising a circumferential surface portion extending around a longitudinal axis and a substantially planar distal portion perpendicular to the longitudinal axis.
