A medical instrument is provided including a device having an expandable portion and a transitional portion. The transitional portion has a spiral cut on the outer surface, and is aligned with the distal portion of a catheter. The transitional portion may be secured to the catheter by a sleeve which is coupled to both the catheter and the transitional portion. Alternatively, the portion of the transitional portion having the spiral cut may be embedded within the catheter.

Transitional geometry for an expandable medical device

A method of treating a thrombus is provided wherein a device is advanced to the vicinity of the thrombus, a thrombolytic agent is applied to the thrombus, and an expandable basket of the device is expanded to capture at least a portion of the thrombus within the expandable basket. The device includes a catheter having a distal portion, a lumen and a plurality of openings on the outer surface of the catheter, through which the thrombolytic agent is supplied. The device further includes a sheath and may include a collar which assists in expanding the expandable basket as the sheath is moved relative to the catheter.

Delivery of thrombolytic agent through actuation member of thrombus retrieval device

A delivery system for a self-expanding medical device is provided. The delivery system includes an outer sheath that radially restrains the medical device. First and second inner catheters are disposed within the outer sheath. The first inner catheter is a composite structure with a closed coil wire covered by a polymer outer layer. The second inner catheter is disposed within the closed coil wire but is not attached to the closed coil wire.
