Basket for a catheter device
First Claim
1. A basket for an infusion catheter 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 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;
a plurality of tubes, each tube comprising a wall with an inner surface and an outer surface and a lumen extending between a distal end and a proximal end;
wherein the plurality of tubes are melted together and to the outside of the shaft at the uncut proximal end of the shaft;
wherein each of the plurality of tines of the shaft are disposed in the lumen of each of the plurality of tubes to form a plurality of limbs;
wherein the plurality of tines independently support the limbs without interconnection of tines between the proximal and distal end of the tines; and
wherein the distal end of each of the plurality of limbs are attached together.

Abstract
The present disclosure relates to a basket for a catheter designed to be deployed in complex vasculature to optimally treat vascular and arterial disease conditions such as blood clots, blood emboli, and deep vein thrombosis. The basket may comprise a shaft with a plurality of cuts along a portion of its length to form a plurality of tines that provide support for a plurality of porous tubes to form the limbs of the basket. The limbs of the basket expand radially away from the longitudinal axis of the basket when the longitudinal length of the basket is reduced. The limbs may also be connected to a drug delivery system, and in this manner, baskets of the present disclosure allow for the use of both mechanical and pharmaceutical means of thrombolysis.
