Orientation markers for endovascular delivery system
First Claim
1. An endovascular stent graft delivery device comprising an elongate body and a length extending module:
- the elongate body comprising a distal portion to remain outside a patient in use and a proximal portion to be introduced into the body to carry a stent graft to a placement site, the proximal portion comprising a nose cone dilator at the proximal end thereof,the length extending module extending proximally of the nose cone dilator, the length extending module comprising a distal end releasably fastened to the nose cone dilator and a proximal end,the length extending module comprising a plurality of longitudinal grooves, each having a distal terminus and a proximal terminus at the distal end and the proximal end of the length extending module, respectively,the nose cone dilator comprising a dilator marker and the length extending module comprising a first marker and a second marker, the first marker being at the distal end of the length extending module and longitudinally spaced apart from the distal terminus of the longitudinal grooves, the second marker being at the proximal end of the length extending module and longitudinally spaced apart from the proximal terminus of the longitudinal grooves, the first marker and the second marker being at the same relative circumferential position on the length extending module and the length extending module being releasably fastened to the nose cone dilator with the first marker and the dilator marker rotationally aligned, whereby the rotational position of the of the portion of the length extending module having the second marker within the patient can be determined by the observation of the position of the second marker relative to the first marker.

Abstract
An endovascular stent graft delivery device has portion to remain outside a patient in use and a proximal portion to be introduced into a patient. The proximal portion has a dilator at the proximal end and a length extending module is fastened to the dilator and extends proximally. The length extending module has a proximal end which in use extends out of the patient. The dilator has a dilator marker and the length extending module has a first and second marker at the distal and proximal ends of the length extending module. The first marker and the second marker are at the same relative circumferential position on the length extending module so that the rotational position of the elongate body within the patient can be determined.
