Methods and systems for performing intralumenal procedures

Abstract

Devices, systems and methods are provided for performing implantation procedures in a desired area of the body. Systems include embodiments of medical implants that include scaffold and inflatable portions and delivery systems to position and release the medical implants at a target location within the body.

That which is claimed is: 
     
         1 . A medical implant system comprising:
 an elongate flexible catheter having proximal and distal ends and a lumen extending therethrough;   a filamentous composite medical implant having an elongate filamentous scaffold portion fixedly coupled to an elongate filamentous expandable portion, said expandable portion including an elongate balloon member and a valve assembly, said scaffold portion being positioned within said balloon member and said balloon member having a length that extends over a substantial portion of the length of said scaffold portion, said balloon member having a first diameter when uninflated and a second diameter when inflated with a fluid; and   an elongate delivery system positioned within the lumen of said catheter including a tubular pusher member having proximal and distal ends and a lumen extending therethrough and a tubular filling member having proximal and distal ends and being positioned within the lumen of said pusher member, said filling member distal end being removably coupled to said medical implant.   
     
     
         2 . A medical implant system according to  claim 1  wherein said elongate scaffold includes an embolic coil. 
     
     
         3 . A medical implant system according to  claim 1  wherein said fluid includes a radiopaque fluid. 
     
     
         4 . A medical implant system according to  claim 1  wherein said fluid comprises a fluid that transitions from a liquid to a solid. 
     
     
         5 . A medical implant system according to  claim 1  wherein at least some of said scaffold portion is positioned within said balloon member. 
     
     
         6 . A medical implant system according to  claim 1  wherein said embolization device includes at least one expansion resisting member positioned at a location along the length of said balloon member to restrict the expansion of said balloon member at said location. 
     
     
         7 . A medical implant system according to  claim 2  wherein said embolic coil includes a shaping member. 
     
     
         8 . A medical implant system according to  claim 2  wherein said embolic coil includes a stretch resistant member. 
     
     
         9 . An apparatus for placement at a target site in the body comprising:
 a medical implant having an elongate filamentous scaffold member and an elongate inflatable balloon member having an interior and a valve assembly wherein said scaffold member is fixedly coupled to said balloon member and is substantially positioned within said interior, said medical implant having a generally linear first configuration during delivery to a target site wherein said balloon member has a first diameter and said implant having a generally complex shaped second configuration upon deployment at the target site wherein said implant is capable of folding upon itself during deployment and said balloon member has a second diameter upon inflation of said balloon member with a fluid wherein said second diameter is greater than said first diameter.   
     
     
         10 . A medical implant according to  claim 9  wherein said elongate scaffold member comprises an embolic coil. 
     
     
         11 . A medical implant according to  claim 9  wherein said fluid includes a radiopaque fluid. 
     
     
         12 . A medical implant according to  claim 9  wherein said fluid comprises a fluid that transitions from a liquid to a solid. 
     
     
         13 . A medical implant according to  claim 9  wherein said balloon member includes at least one expansion resisting member to restrict the expansion of said balloon member. 
     
     
         14 . A medical implant according to  claim 10  wherein said embolic coil includes a shaping member. 
     
     
         15 . A medical implant according to  claim 10  wherein said embolic coil includes a stretch resistant member. 
     
     
         16 . A medical implant according to  claim 10  wherein at least one of said balloon member and scaffold member comprises a bioactive therapeutic material. 
     
     
         17 . A medical implant system comprising:
 an elongate flexible catheter having proximal and distal ends and a lumen extending therethrough;   an elongate medical implant having an elongate scaffold portion and an inflatable portion comprising a balloon member having a valve assembly, said scaffold portion being fixedly coupled to and positioned adjacent said inflatable portion, wherein said implant is capable of folding upon itself during deployment at a target site; and   an elongate delivery system positioned within the lumen of said catheter including a pusher member having proximal and distal ends and a tubular filling member having proximal and distal ends and being adapted to deliver a fluid to inflate said inflatable portion, said filling member distal end being removably coupled to said medical implant.   
     
     
         18 . A medical implant system according to  claim 17  wherein said elongate scaffold portion includes an embolic coil. 
     
     
         19 . A medical implant system according to  claim 18  wherein said fluid includes a radiopaque fluid. 
     
     
         20 . A medical implant system according to  claim 18  wherein said fluid comprises a fluid that transitions from a liquid to a solid.
