1. A catheter comprising:
a basket comprising:
a shaft comprising a wall with an inner surface and an outer surface and a lumen extending between a distal end and a proximal end and defining a longitudinal axis, wherein a plurality of helical cuts along at least a portion of the shaft between the inner and outer surface of the wall form a plurality of tines,
wherein the proximal end of the shaft is uncut; and
a plurality of tubes, each tube comprising a lumen extending between a distal end and a proximal end;
wherein:
the plurality of tubes are melted together and to an outside of the shaft at the uncut proximal end of the shaft, and
each of the plurality of tines of the shaft is disposed in the lumen of each of the plurality of tubes to form a plurality of limbs;
an inner shaft disposed coaxially within the lumen of the shaft and is attached to the distal end of the basket; and
an outer shaft disposed coaxially around the inner shaft to form a fluid compartment between an inner surface of the outer shaft and an outer surface of the inner shaft,
wherein:
the proximal end of the limbs of the basket is connected to the fluid compartment, and
the connection between the proximal end of the limbs of the basket and the fluid compartment comprises a seal disposed between the inner shaft and the proximal end of the plurality of limbs, and the seal extends distally from the outer shaft.
