Dual stent and delivery system, delivery tool apparatus, and method of delivery of dual stents

Abstract

A method, system, or apparatus for stent delivery. Delivering one or more stents with a delivery tool that can include a kinetic transfer of energy to deliver one or more stents. The stents can include a modifiable stent that can change its overall shape and/or dimensions based on pre-configured design parameters. A coil stent that can engage with a vessel that surrounds the modifiable stent forming a dual stent configuration. The coil stent can also include anchor points that allow it to engage with a second vessel securing the first vessel and the second vessel together to aid in the healing process.

1 . A dual stent delivery system comprising:
 a delivery tool with a main body having a first end and a second end;   a back stop removably coupled to the second end of the main body;   a body aperture defined by the first end of the main body;   a shaft passing through the body aperture, a cover carrier with a void that allows for the passage of the shaft through the cover carrier;   a retention mechanism coupled to the back stop and the cover carrier; and a firing button that is removably engaged with the cover carrier until a force is applied to it such that the cover carrier moves towards the backstop;   a modifiable stent coaxially positioned around the shaft with a modifiable stent cover surrounding the modifiable stent; and   a coil stent coaxially positioned around the shaft, the modifiable stent, and a coil stent cover that is positioned closer to the shaft than the coil stent.   
     
     
         2 . (canceled)

         5 . The dual stent deliver system of  claim 1 , wherein the modifiable stent expands radially outward after the firing button has the force applied to it. 
     
     
         6 . The dual stent delivery system of  claim 1 , wherein the coil stent retracts radially inward after the firing button has the force applied to it. 
     
     
         7 . A stent delivery system comprising:
 a combination tool;   a compressible stent;   a coil stent; and   a tweezer tool;   wherein the combination tool receives a first end of the compressible stent, and a portion of the tweezer tool, and the tweezer tool engages a first end of the coil stent.   
     
     
         8 . The stent delivery system of  claim 7 , wherein the combination tool is configured to receiving at least a first end of the compressible stent. 
     
     
         9 . The stent delivery system of  claim 7 , wherein the combination tool further comprises a stent receiving aperture. 
     
     
         10 . The stent delivery system of  claim 7 , wherein the combination tool further comprises at stent receiving channel. 
     
     
         11 . The stent delivery system of  claim 7 , wherein the combination tool further comprises a stent deployment point. 
     
     
         12 . The stent delivery system of  claim 7 , wherein the combination tool further comprises a handle. 
     
     
         13 . The stent delivery system of  claim 7 , wherein the combination tool further comprises a main body. 
     
     
         14 . The stent delivery system of  claim 7 , wherein the compressible stent is contained within a sheath. 
     
     
         15 . The stent delivery system of  claim 14 , wherein the combination tool engages the sheath to allow for complete removal of the sheath from the stent. 
     
     
         16 . The stent delivery system of  claim 7 , wherein the combination tool receives at least a first end of the compressible stent. 
     
     
         17 . The stent delivery system of  claim 7 , wherein the combination tool receiving at least a first end of the compressible stent within a main body of the combination tool. 
     
     
         18 . The stent delivery system of  claim 7 , wherein the combination tool engages with a first end of the tweezer tool. 
     
     
         19 . The stent delivery system of  claim 7 , wherein the combination tool engages with a first end of the tweezer tool at a stent receiving aperture. 
     
     
         20 . The stent delivery system of  claim 7 , wherein the compressible stent is coaxial to the tweezer tool that is at least partially coaxial to the combination tool at a first end of the tweezer tool, and the tweezer tool is coaxial to the coil stent at a second end of the tweezer tool. 
     
     
         21 . The stent delivery system of  claim 7 , wherein the combination tool further comprises a main body configured to receive a portion of the compressible stent with a stent receiving channel, and the combination tool engages the compressible stent with a stent deployment point; wherein the combination tool engages with a first end of the tweezer tool at a stent receiving aperture; and wherein the tweezer tool is engages with the compressible stent to apply a compression force to it, while providing an engagement surface for the coil stent at a second end of the tweezer tool.
