Abstract: Expandable electrophysiology catheters having electrodes mounted on splines of an expandable member are described. The splines of the expandable member include subsegments between a proximal location and a distal intersection at a central axis. The subsegments can include respective top-down profiles, and at least one of the top-down subsegment profiles is straight between the central axis and an adjacent top-down subsegment profile. The subsegments can be interconnected to extend continuously about the central axis from the proximal location to the distal intersection. Other embodiments are also described.

Abstract: A versatile orthopedic walker includes a high strength engineered plastic base with spaced upper and lower surfaces and upwardly extending slotted strut supports. The base may be laterally and vertically cored, and an outer sole is provided which extends upward over the core openings, with the upper edges of the outsole being ridged to fit into a peripheral groove in the base to provide a smooth exterior surface. Struts of different lengths are provided, and all of the struts have identical arrangements for interlocking with the base. All of the struts may be provided with a three pronged construction to triply lock the struts into the base. The struts may have areas of reduced cross-section providing pivot points or areas of flexibility to accommodate different size patients, and limiting stops may be provided to assure adequate orthopedic support. Fully integrally molded pivoting D-rings may hold walker straps in place.
