Stents and stent deployment devices
First Claim
1. A stent deployment system, comprising:
- a handle body;
a stent holding assembly including a first holder and a second holder, the stent holding assembly connected to the handle body, wherein the first holder is connected to the second holder via a shaft defining a longitudinal axis such that the first and second holders are substantially aligned with the longitudinal axis;
a stent having a proximal end and a distal end, the stent secured to the stent holding assembly such that at least a portion of the stent holding assembly is confined within the stent;
a first protective cover disposed at one end of the first holder, the first protective cover configured to enclose a first fastening assembly; and
a second protective cover disposed at one end of the second holder, the second protective cover configured to enclose a second fastening assembly, each of the first and second fastening assemblies including a plurality of anchors, wherein the plurality of anchors are movable from a straight configuration when enclosed by the respective first and second protective covers to a bent configuration when the plurality of anchors are released from the respective first and second protective covers.

Abstract
A method of deploying a stent includes receiving a delivery system loaded with a stent and securing the stent in a compressed arrangement by a stent holding assembly including first and second holders having a first protective cover disposed at one end for enclosing a first fastening assembly and a second protective cover disposed at one end of the second holder for enclosing a second fastening assembly, respectively, the stent coupled to the first and second holders members by the first and second fastening assemblies, respectively. The method further includes delivering the stent in an axially expanded and a radially compressed arrangement to an implantation site, retracting the first and second protective covers to expose the first and second fastening assemblies, and actuating the first and second fastening assemblies such that the stent radially expands to engage an inner wall of a lumen.
