Abstract
The disclosed technology includes a spine member for an end effector, the spine member extending along a longitudinal axis from a proximal end to a distal end. The spine member includes a unidirectional proximal stop member to allow an electrode to slide in a direction distally but not proximally and a distal stop member to prevent an electrode from sliding past.
Claims20
An expandable basket assembly for a medical probe, comprising:
- a plurality of spines configured to bow radially outward from a central axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form, each spine of the plurality of spines comprising at least one aperture extending therethrough;
- and
- at least one electrode configured to be coupled to a spine of the plurality of spines, the at least one electrode comprising:
- a lumen extending therethrough configured to receive the spine;
- and
- a locking stub extending at least partially into the lumen and configured to extend at least partially through the at least one aperture of the spine.
A method of constructing a medical probe, the method comprising:
- aligning a spine of an expandable basket assembly with an electrode of the expandable basket assembly, the spine comprising a proximal end, a distal end, and an aperture extending therethrough;
- inserting the spine into a lumen of the electrode;
- aligning a locking stub of the electrode with the aperture;
- and
- mechanically coupling the electrode onto the spine such that the locking stub extends at least partially into the aperture to prevent the electrode from sliding proximally or distally along the spine.
