Aspiration catheter

A thrombectomy system, comprising:

• a processor coupled to a pump and a thrombectomy catheter, wherein the thrombectomy catheter includes:
• an outer shaft having a proximal end region attached to a manifold, a distal end region and a lumen extending therein;
• a tip member having a length and a lumen extending therein, wherein the tip member is coupled to the distal end region of the outer shaft;
• and
• a guidewire shaft having a proximal end region and a distal end region;
• wherein the guidewire shaft extends within at least a portion of the lumen of the outer shaft and the lumen of the tip member;
• wherein the distal end region of the guidewire shaft includes an interlock region, and wherein a portion of the tip member is engaged with at least a portion of the interlock region of the guidewire shaft.

A method of manufacturing a thrombectomy catheter, the method comprising:

• positioning an outer shaft adjacent a tip member, whereby a lumen of the outer shaft is in fluid communication with a lumen of the tip member;
• positioning a guidewire shaft within the lumen of the outer shaft and the lumen of the tip member, wherein the guidewire shaft includes an interlock region having a plurality of discrete slots extending radially inward from an outer surface of the guidewire shaft;
• aligning the guidewire shaft relative to the tip member such that a portion of the interlock region is positioned adjacent to the tip member;
• and
• reflowing the tip member such that a portion of the tip member extends into each of the discrete slots of the interlock region.
