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.

The disclosed technology includes a medical probe including a tubular shaft having a proximal end and a distal end. The tubular shaft can extend along a longitudinal axis. The medical probe can include an expandable basket assembly proximate the distal end of the tubular shaft. The expandable basket assembly can include a single spine comprising a resilient material extending generally linearly along the longitudinal axis in a collapsed form and forming a spiral member defining a generally spherical outer periphery in an expanded form. One or more electrodes can be coupled to the single spine. Each electrode can include a lumen offset with respect to a centroid of the electrode so that the single spine extends through the lumen of each of the one or more electrodes.

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 first unitary tripodic structure and a second unitary tripodic structure, each tripodic structure formed from a respective planar sheet of material that includes three linear spines converging at a respective central spine intersection and one or more electrodes coupled to each of the spines, each electrode defining a lumen through the electrode so that the spine extends through the lumen of each of the one or more electrodes. Each tripodic structure formed from a respective planar sheet of material that includes three linear spines converging at a respective central spine intersection.

A medical probe includes a shaft, an expandable membrane and a probe maneuvering assembly (PMA). The shaft is configured for insertion into a cavity of an organ of a patient. The PMA is located inside the expandable membrane and includes a first elastic element, which is fitted along a longitudinal axis of the PMA and is configured to expand the membrane by shortening the PMA, and to collapse the membrane by elongating the PMA. The PMA further includes a second elastic element, which surrounds at least a portion of the first elastic element and is configured to deflect the membrane relative to the longitudinal axis.

Balloon catheter with high articulation

A surgical tool, consisting of a handle and a flexible insertion tube, having a proximal end coupled to the handle and a distal end configured to be inserted into an orifice of a living subject. The tool has an inner tube, which is bendable without breaking over a range of angles in response to a bending force, and which retains the bent shape after the bending force has been removed. The inner tube is located within the insertion tube. A flexible tubing defines a lumen and is contained within the inner tube. A tool working tip is configured to contact tissue in the subject and to mate with a distal termination of the inner tube. A rigid outer tube grips outer surfaces of the working tip and of the inner tube so as to maintain an opening of the working tip in communication with the flexible tubing lumen.
