Intraluminal graft device, system and method
First Claim
1. A system for intraluminally engrafting in a fluid conducting corporeal lumen comprising:
- a hollow graft of preselected cross-section and length and having a proximal end for placement upstream within said lumen, said graft being deformable to substantially conform to the interior surface of said lumen;
a plurality of staples adapted proximate the proximal end of said graft and extending therethrough for stapling said graft to and within said lumen;
placement means for emplacing said graft into said lumen, for positioning it at a preselected position within said lumen, and for causing at least one of said staples to engage said lumen, said placement means including;
guide means having a front and back and sized for positioning in said lumen, said guide means having road means adapted to the back thereof sized in length to extend exterior said lumen for manipulation by the user, said guide means back having a cavity formed therein with said rod being centrally positioned within said cavity wherein said proximal end of said graft is retained within said cavity for purposes of positioning said graft in said lumen; and
operation means for removing said graft from said guide means and for positioning said staples into said lumen;
said operation means including a hollow tube for slideable positioning over said rod and sized in length to extend from said cavity to exterior said lumen, said tube having an inflatable membrane proximate the cavity end of said tube, and a channel in communication with said inflatable membrane and extending along the length of said tube, and inflation means connectable to said channel exterior said lumen for inflating and deflating said inflatable membrane.

Abstract
An intraluminal grafting system includes a hollow graft which has a plurality of staples adapted proximate its proximal end. The system includes a guide for positioning the proximal end of the graft upstream in a lumen which may be a blood vessel or artery. The back of the guide has a cavity into which the proximal end of the graft is retained. A rod extends from the cavity to exterior the lumen for manipulation by the user. A tube is positioned over the rod to extend from the cavity and through the graft to exterior the lumen. The tube has an inflatable membrane proximate the cavity end thereof which is in communication via a channel with inflation and deflation means located exterior the lumen. With the inflatable membrane deflated, the guide means is positioned into the lumen and manipulated to a desired location. The inflatable membrane is inflated to place a force against the staples as the guide is manipulated by the rod away from the graft. The force exerted by the inflatable membrane forces the staples into the lumen.

5. A method for artificially and intraluminally engrafting in a fluid conducting corporeal lumen comprising:
-
making an access to and an opening in a corporeal lumen; providing apparatus for intraluminal engrafting which apparatus includes; a hollow graft of preselected cross-section and length and having a proximal end for placement upstream within said lumen, said graft being deformable to substantially conform to the interior surface of said lumen, a plurality of staples adapted proximate the proximal end of said graft and extending therethrough for stapling said graft to and within said lumen, guide means having a back with a cavity formed therein and a front, and sized for positioning in said lumen, said guide means having rod means centrally positioned in and secured within said cavity and sized in length to extend exterior said lumen for manipulation, said guide means having means to retain said proximal end of said graft for positioning of said graft in said lumen, a hollow tube for slideable positioning over said rod and sized in length to extend from said cavity to exterior said lumen, said tube having an inflatable membrane proximate the cavity end of said tube, and a channel in communication with said tube and inflation means connectable to said channel exterior said lumen for inflating and deflating said inflatable membrane; inserting said guide means and hollow graft into said opening and urging said guide means and hollow graft upstream in said lumen to a desired location therewithin; operating said inflation means and said guide means to disassociate said graft from said guide means and to cause at least one staple to engage the lumen; operating said inflation means and said guide means to remove them from said lumen; and closing said opening and said access. - View Dependent Claims (6, 7)
