Abstract
The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent including a main body and at least one lateral side branch connected to the main body. A system of covered stents and a method for implanting, including interconnecting the covered stents is also disclosed.
Claims20
A stent delivery system comprising:
- a first covered stent having a side branch;
- a guiding element having an elongated shape and being distally attached at a connection point at said side branch of said first covered stent;
- a second covered stent configured to be connected to said first covered stent;
- a delivery catheter comprising a delivery lumen with a distal orifice for delivery and deployment of said second covered stent at a target site of said side branch of said first covered stent;
- and
- a guiding mate through which said guiding element is positioned and connected to said delivery catheter, such that said catheter slides along said guiding element to an orifice of said branch, wherein said guiding mate has a distal end positioned proximally at a distance from said distal orifice of said delivery lumen such that said delivery lumen extends beyond said connection point when said distal end of said guiding mate is positioned adjacent to said connection point,
- wherein said connection point limits said guiding mate from further distal advancement beyond said connection point while allowing said delivery lumen of said catheter to extend beyond said connection point during a delivery procedure of said second covered stent.

A covered stent delivery system comprising:
- at least one covered stent with a main body and at least one lateral side branch connected to said main body;
- a second covered stent configured to be connected to said lateral side branch of said main body;
- a delivery catheter comprising a delivery lumen with a distal orifice and a guiding mate with a second lumen, wherein said distal orifice of said delivery lumen is positioned at a distance from a distal end of said second lumen of said guiding mate;
- a guiding element having a distal end attached to a distal end of said lateral side branch at a connection point and a proximal end attached to a proximal end of said second lumen of said guiding mate;
- wherein said delivery catheter is configured to slide along said guiding element through said guiding mate and said delivery lumen of said delivery catheter is configured to deliver and deploy said second covered stent at said distal end of said lateral side branch of said at least one covered stent with said main body;
- and
- wherein said connection point is configured to stop said distal end of said second lumen of said guiding mate while allowing a distal portion of said delivery lumen of said delivery catheter to extend beyond said connection point during a delivery procedure of said second covered stent.
4 more elements
A method of interconnecting a plurality of covered stents in a covered stent delivery system comprising the steps of:
- providing a first covered stent having a side branch and a second covered stent configured to be connected to said first covered stent;
- providing a guiding element having an elongated shape and attaching said guiding element distally at a connection point at said side branch of said first covered stent;
- providing a delivery catheter comprising a delivery lumen with a distal orifice and a guiding mate with a second lumen and positioning said distal orifice of said delivery lumen at a distance from a distal end of said second lumen of said guiding mate;
- attaching said guiding element through said guiding mate to said delivery catheter;
- sliding said delivery catheter containing said second covered stent along said guiding element;
- positioning said distal end of said guiding mate adjacent to said connection point while extending said delivery lumen of said delivery catheter beyond said connection point;
- and
- connecting said second covered stent at a target site of said side branch of said first covered stent after delivering and deploying said second covered stent from said delivery lumen of said delivery catheter.
