Abstract
A method of making a spacer cage is disclosed. The method may include providing a tube having an outer diameter, a first second, a second section and a middle section having a first end connected to the first section and a second end connected to the second section, cutting the middle section to form strut elements of the spacer cage and cutting a plurality of longitudinal slits in the first and second sections to allow radial expansion of the first and second sections, expanding the tube using a mandrel, heat setting the tube while on the mandrel, and subsequent the heat setting, removing the first and second sections from the tube.

A method of making a spacer cage for use with a renal nerve modulation device, the method comprising:
- providing a tube having an outer diameter, a first section, a second section, and a middle section having a first end connected to the first section and a second end connected to the second section;
- cutting the middle section to form strut elements of the spacer cage and cutting a plurality of longitudinal slits in the first and second sections to allow radial expansion of the first and second sections;
- expanding the tube using a mandrel;
- heat setting the tube while on the mandrel;
- and
- subsequent the heat setting, removing the first and second sections from the tube.
A method for manufacturing a renal nerve modulation device, the method comprising:
- providing a tubular member;
- cutting the tubular member to define one or more strut assemblies;
- wherein each of the strut assemblies include a main strut, a spacer strut, and an electrode strut;
- wherein an electrode is coupled to the electrode strut;
- removing one or more end portions from the tubular member to define a cage member;
- and
- attaching the cage member to a catheter shaft.
A precursor formed from a cylindrical tube having a first end and a second end and a longitudinal axis extending from the first end to the second end, comprising:
- a first section at the first end;
- and
- a primary section having a first end region and a second end region, the first end region abutting the first section;
- the primary section comprising a plurality of slits extending from the first end region to the second end region;
- the first section comprising a plurality of longitudinal slits configured so as to allow radial expansion of the first section;
- wherein the primary section comprises one or more strut assemblies, the strut assemblies each including a first main strut section, a second main strut section extending from a second section, a pair of spacer strut sections extending between the first main strut section and the second main strut section, and an electrode support strut extending from the first main strut section between the pair of spacer strut sections;
- and
- wherein the electrode support strut is configured to have an electrode coupled thereto.
