Abstract
The disclosed technology includes an electrode for a medical probe having an elongated body. At least a portion of the elongated body can be electrically conductive. The elongated body can define a lumen that extends through the elongated body along a longitudinal axis of the elongated body. The electrode can include a locking stub that extends at least partially into the lumen so that the locking stub is locked to a member inserted into the lumen.
Claims20
An electrode for a medical probe, the electrode comprising:
- an elongated body comprising an electrically conductive portion, the elongated body defining a lumen extending through the elongated body along a longitudinal axis of the elongated body;
- and
- a locking stub extending at least partially into the lumen, the locking stub configured to be locked to a spine inserted into the lumen such that the electrode is prevented from sliding distally or proximally along the spine.
A medical probe, comprising:
- a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis;
- and
- an expandable basket assembly coupled to the distal end of the tubular shaft, the expandable basket assembly comprising:
- a plurality of electrodes, each electrode of the plurality of electrodes (i) comprising an elongated body comprising an electrically conductive portion, (ii) defining a lumen extending through the elongated body along the longitudinal axis, and (iii) comprising a locking stub extending at least partially into the lumen;
- and
- a plurality of spines extending along the longitudinal axis, each spine of the plurality of spines passing through a lumen of an electrode of the plurality of electrodes, the locking stub of each electrode being mechanically coupled to a respective spine of the plurality of spines such that each electrode is prevented from sliding distally or proximally along the respective 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 defining an aperture extending therethrough;
- inserting the spine into a lumen of the electrode;
- aligning a locking stub of the electrode with the aperture;
- crimping 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;
- and
- electrically isolating the electrode from the spine using an insulative material.
