    摘要: The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis of the medical probe. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly comprises a plurality of spines and a plurality of electrodes. The electrode comprises an electrode body that defines a lumen therethrough such that the respective spine extends through the lumen. The respective electrode body comprises two sections that define a lengthwise direction of the electrode body section that are inclined inward with respect to a central axis of the respective electrode.

    摘要: The disclosed technology includes a medical probe comprising a tubular shaft extending along a longitudinal axis and including a proximal end and a distal end. The medical probe further comprises an expandable basket assembly proximate the distal end of the tubular shaft. The basket assembly comprises a single unitary structure that includes a plurality of linear spines formed from a planar sheet of material and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that a spine extends through the lumen of each of the one or more electrodes. The spines converge at a central spine intersection at a distal end of the basket assembly. The central spine intersection includes one or more cutouts that allows for bending of the spines. Each spine comprises a respective end connected to the distal end of the tubular shaft.

    摘要: The disclosed technology includes a medical probe comprising a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly includes a plurality of electrodes with each electrode of the plurality of electrodes having a lumen therethrough. The basket assembly further includes a plurality of spines extending along the longitudinal axis and configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form. Each spine includes a proximal and a distal end and a strut passing through the lumen of an electrode. The strut includes a mechanical retainer disposed on the strut to prevent the electrode from sliding proximally or distally along a length of the spine.
