Integrated sheath and deployment
First Claim
Patent Images
1. A catheter assembly for endoluminal deployment of a medical device to a treatment site in a human patient, said catheter assembly comprising:
- a catheter having a proximal end and an opposite distal end;
a device disposed near the distal end of the catheter and constrained to an outer peripheral dimension suitable for endoluminal delivery of the device to the treatment site;
a sleeve that extends over the device;
a first deployment line releasably coupling opposite sides of the sleeve to form a first seam along a first portion of the sleeve; and
a second deployment line releasably coupling opposite sides of the sleeve to form a second seam along a second portion of the sleeve,wherein displacement of the first deployment line and second deployment line in a first direction causes decoupling of the first seam and second seam, respectively, the first deployment line and second deployment line being operatively coupled to each other so as to delay decoupling of the second seam until substantially after decoupling of the first seam,including a third deployment line fixedly secured to the sleeve to allow retraction of the sleeve upon displacement of the third deployment line in the first direction, the third deployment line having a length of slack generally equal to or greater than the length of the first portion of the sleeve to delay retraction of the sleeve until after the first portion of the sleeve has been opened.
