Stent graft delivery device pre-loaded with a single wire for device tracking and cannulation

A pre-loaded prosthesis delivery device comprising:

• a delivery catheter having a proximal end,
• a prosthesis releasably coupled to the proximal end of the delivery catheter, wherein the prosthesis has a proximal end, a distal end, and a lumen extending there between,
• a nose cone dilator extending from the proximal end of the delivery catheter, wherein the nose cone comprises a proximal end having a proximal opening, a distal end, and a sidewall extending between the proximal and distal ends, a substantially straight internal lumen extending through the nose cone dilator between the proximal opening and the distal end, an opening formed in the sidewall, an angled internal channel extending from the opening formed in the sidewall to the proximal opening, wherein a length of the internal channel extending between the opening formed in the sidewall and the proximal opening is greater than an inner diameter of the channel measured adjacent to the opening formed in the sidewall and wherein the angled internal channel extends to the substantially straight internal lumen and is in fluid communication with the substantially straight internal lumen,
• a secondary catheter having a delivery configuration and a released configuration, wherein, in the delivery configuration the secondary catheter extends through at least a portion of the prosthesis lumen, into the opening formed in the sidewall of the nose cone and extends at least partially into the internal channel formed in the nose cone, and in the released configuration the secondary catheter is retracted distally out of the internal channel formed in the nose cone dilator.

A method of delivering a prosthesis comprising;

• tracking a prosthesis delivery device to a desired position within a main vessel lumen, the delivery device comprising
• a delivery catheter having a tubular prosthesis releasably coupled thereto and
• a nose cone extending from the proximal end of the delivery catheter, wherein the nose cone comprises a proximal end having a proximal opening, a distal end, and a sidewall extending between the proximal and distal ends, a substantially straight internal lumen extending through the nose cone dilator between the proximal opening and the distal end, an opening formed in the sidewall, an angled internal channel extending from the opening formed in the sidewall to the proximal opening and wherein a length of the internal channel extending between the opening formed in the sidewall and the proximal opening is greater than an inner diameter of the channel measured adjacent to the opening formed in the sidewall and wherein the angled internal channel is in fluid communication with the substantially straight internal lumen, and
• a secondary catheter extending through at least a portion of the tubular prosthesis and extending at least partially into the internal channel formed in the nose cone,
• distally retracting the secondary catheter to release it from the internal channel,
• manipulating the secondary catheter to cannulate a branch vessel extending from the main vessel.
