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.
Claims19
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:
- a proximal electrode stop configured to allow a distal electrode to slide distally on each spine past the proximal electrode stop but prevent a proximal electrode from sliding distally past the proximal electrode stop;
- and
- a distal electrode stop configured to prevent the distal electrode from sliding distally past the distal electrode stop.
