Delivery System With Curved Preloaded Catheter
First Claim
Patent Images
1. A delivery system for a medical device comprising:
- a first catheter having a distal end, a proximal end, and a longitudinal axis;
a nose cone dilator disposed at the proximal end of the first catheter, the nose cone dilator having a groove formed in an outer surface of the nose cone dilator, the groove having a distal portion parallel to the longitudinal axis and a proximal portion extending circumferentially about the outer surface; and
a second catheter, pre-loaded in the delivery system, and having a proximal end and a distal end, the second catheter proximal end being disposed in at least the proximal portion of the groove and extending from the proximal portion of the groove to the distal portion of the groove.

Abstract
A delivery system for a medical device includes a proximal tip having a curved groove formed therein and a pre-loaded catheter disposed in the groove such that the pre-loaded catheter is disposed at least partly circumferentially with regard to the proximal tip. A guidewire can be advanced through the pre-loaded catheter and extended laterally from the delivery system.

10. A delivery system for a medical device comprising:
-
a delivery catheter having a proximal tip and a longitudinal axis; a groove disposed in an exterior surface of the proximal tip, the groove having a distal portion parallel to the longitudinal axis and a proximal portion extending circumferentially about the proximal tip; a sheath disposed at least partially over the proximal tip and the groove, the sheath slidable in a longitudinal direction relative to the delivery catheter from a first position to a second position; and a pre-loaded guiding catheter extending a length of the delivery catheter and disposed in the groove. - View Dependent Claims (11, 12, 13, 14, 16)

17. A method of delivering a guidewire comprising:
-
accessing a delivery system comprising; a delivery catheter having a proximal tip; a groove disposed in a surface of the proximal tip, the groove having a distal portion parallel to a longitudinal axis of the catheter and a proximal circumferential portion; a sheath covering the groove, the sheath movable from a first position covering the groove to a second position at which a proximal portion of the groove in uncovered; a fenestrated stent graft disposed between the sheath and the delivery catheter, the fenestrated stent graft having a side branch extending from the fenestrated stent graft between a proximal end and distal end of the fenestrated stent graft; a guiding catheter extending from the side branch into the proximal portion of the groove; and a guidewire disposed in the guiding catheter; introducing the delivery system into a vessel lumen; moving the sheath from the first position to the second position exposing a portion of the groove and guiding catheter; and extending the guidewire from the guiding catheter lateral relative to the delivery catheter. - View Dependent Claims (18, 19, 20)
