Surgical implant devices and methods for their manufacture and use

Abstract

A method of implanting a prosthetic medical device at a target implantation site is provided. The method first comprises advancing a first prosthetic medical device through a subject's vasculature to a target implantation site. The first prosthetic medical device comprises a coil having an inflow end portion, an outflow end portion, and a central longitudinal axis extending from the inflow end portion to the outflow end portion. The method further comprises expanding the first prosthetic medical device from a compressed state to an expanded state to engage native vascular tissue at the target implantation site. The method subsequently comprises docking a second prosthetic medical device within the first prosthetic medical device.

We claim: 
     
         1 . A method of implanting a prosthetic medical device, comprising:
 advancing a first prosthetic medical device through a subject's vasculature to a target implantation site, wherein the first prosthetic medical device comprises a coil having an inflow end portion, an outflow end portion, and a central longitudinal axis extending from the inflow end portion to the outflow end portion;   expanding the first prosthetic medical device from a compressed state to an expanded state to engage native vascular tissue at the target implantation site; and   docking a second prosthetic medical device within the first prosthetic medical device.   
     
     
         2 . The method of  claim 1 , wherein the target implantation site includes a native aorta. 
     
     
         3 . The method of  claim 1 , wherein the first prosthetic medical device further comprises a foam gasket disposed around the coil. 
     
     
         4 . The method of  claim 3 , wherein the foam gasket is disposed on a radially facing outer surface of the coil. 
     
     
         5 . The method of  claim 1 , wherein the first prosthetic medical device further comprises a fabric covering disposed around the coil. 
     
     
         6 . The method of  claim 1 , wherein the coil has at least one loop. 
     
     
         7 . The method of  claim 1 , wherein the coil of the first prosthetic medical device comprises a first end and a second end, wherein the first end is spaced from the second end. 
     
     
         8 . The method of  claim 1 , wherein the first prosthetic medical device is expanded from the compressed state to the expanded state in a radial direction substantially perpendicular to the central longitudinal axis. 
     
     
         9 . The method of  claim 1 , wherein at least a portion of the first prosthetic medical device is self-expandable. 
     
     
         10 . The method of  claim 9 , wherein the self-expandable portion of the first prosthetic medical device is fabricated from a shape memory material. 
     
     
         11 . The method of  claim 10 , wherein the shape memory material is Nitinol. 
     
     
         12 . A method of implanting a surgical implant device, comprising:
 advancing a delivery apparatus and a first surgical implant device releasably coupled to a distal portion of the delivery apparatus through a subject's vasculature to a target implantation site, wherein the first surgical implant device comprises an annular body having an inflow end portion, an outflow end portion, and defines a lumen extending from the inflow end portion to the outflow end portion;   deploying the first surgical implant device to an expanded state to engage walls of native tissue at the target implantation site; and   inserting a second surgical implant device into the lumen of the first surgical implant device.   
     
     
         13 . The method of  claim 12 , wherein the annular body forms a loop in a circumferential direction and has a first end and a second end. 
     
     
         14 . The method of  claim 13 , wherein the first end of the loop is in a spaced radially from the second end of the loop. 
     
     
         15 . The method of  claim 14 , wherein the first end of the loop is spaced circumferentially from the second end of the loop. 
     
     
         16 . The method of  claim 12 , wherein at least a portion of the first surgical implant device is self-expandable. 
     
     
         17 . A method of implanting a prosthetic medical device, comprising:
 advancing a delivery apparatus and a docking implant releasably coupled to a distal end portion thereof through a subject's vasculature to a target implantation site, wherein the docking implant comprises a self-expanding circumferential implant body having a proximal end portion, and distal end portion, and a central longitudinal axis extending from the proximal end portion to the distal end portion;   deploying the docking implant from the delivery apparatus such that the circumferential implant body self-expands from a compressed state to an expanded state such that the circumferential implant body engages native vascular tissue at the target implantation site; and   docking a prosthetic medical device within the docking implant.   
     
     
         18 . The method of  claim 17 , wherein the docking implant further comprises a covering disposed on a radially outer surface of the circumferential implant body. 
     
     
         19 . The method of  claim 18 , wherein the delivery apparatus comprises a sheath and a lumen disposed at the distal end portion of the delivery apparatus, wherein the lumen contains the docking implant in the compressed state prior to deployment. 
     
     
         20 . The method of  claim 19 , wherein the circumferential implant body comprises a loop having a first end portion and a second end portion, wherein the first end portion is spaced apart from the second end portion.
