Percutaneous endovascular apparatus for repair of aneurysms and arterial blockages

Abstract

An endovascular apparatus is provided for treating the effects of vascular disease including aneurysms and arterial blockages using a percutaneous, minimally invasive technique. In one embodiment the endovascular apparatus includes a tubular sleeve having a cranial end, a first caudal branch, and a second caudal branch such that the tubular sleeve is shaped like an upside down “Y.” The apparatus further includes at least one expandable attachment device attached to the tubular sleeve for securing the endovascular apparatus to an interior wall of a vessel.

1 . An endovascular apparatus comprising:
 a tubular sleeve having a central lumen with a cranial end portion, a first caudal branch, and a second caudal branch;   a plurality of M configuration springs attached to the cranial end portion of the tubular sleeve extending circumferentially around the tubular sleeve to hold the sleeve open and secure the sleeve to a wall of a vessel.   
     
     
         2 . An endovascular apparatus of  claim 1 , wherein the plurality of M configuration springs comprise a plurality of telescoping arms. 
     
     
         3 . An endovascular apparatus as in  claim 1 , wherein the tubular sleeve comprises a synthetic polyester. 
     
     
         4 . An endovascular apparatus as in  claim 1 , wherein the tubular sleeve comprises an endovascular graft material. 
     
     
         5 . An endovascular apparatus as in  claim 1 , wherein the first caudal branch and the second caudal branch each include a plurality of M configuration springs. 
     
     
         6 . An endovascular apparatus as in  claim 1 , further comprising a first attachment device extending cranially of the cranial end portion of the tubular sleeve. 
     
     
         7 . An endovascular apparatus as in  claim 6 , wherein the first attachment device is radially expandable from a first configuration to a second configuration. 
     
     
         8 . An endovascular apparatus as in  claim 7 , wherein the first attachment includes telescoping arms. 
     
     
         9 . An endovascular apparatus comprising:
 a tubular sleeve having a central lumen with a cranial end portion, a first caudal branch, and a second caudal branch;   an M-stent attached to the cranial end portion of the tubular sleeve extending circumferentially around the tubular sleeve to hold the sleeve open and secure the sleeve to a wall of a vessel.   
     
     
         10 . The endovascular apparatus of  claim 9 , wherein the M-stent comprises a plurality of telescoping arms. 
     
     
         11 . An endovascular apparatus as in  claim 9 , wherein the tubular sleeve comprises a synthetic polyester. 
     
     
         13 . An endovascular apparatus as in  claim 9 , wherein the tubular sleeve comprises an endovascular graft material. 
     
     
         14 . An endovascular apparatus as in  claim 9 , wherein the first caudal branch and the second caudal branch each include an M-stent. 
     
     
         16 . An endovascular apparatus as in  claim 9 , further comprising a first attachment device extending cranially of the cranial end portion of the tubular sleeve. 
     
     
         17 . An endovascular apparatus as in  claim 16 , wherein the first attachment device is radially expandable from a first configuration to a second configuration. 
     
     
         18 . An endovascular apparatus as in  claim 17 , wherein the first attachment includes telescoping arms.
