Abstract
A guide sheath device with an integrated stabilization wire is provided. The guide sheath device includes an elongate member having a proximal and distal end and a lumen there between and a stabilization wire integrated to the elongate member.
Claims22
A guide sheath apparatus for performing a lower extremity endovascular procedure, the apparatus comprising:
- an elongate member having a proximal and distal end and a lumen therebetween, the elongate member configured to be inserted into a lower extremity vasculature via a contralateral percutaneous access;
- and
- a stabilization wire having a proximal end and a distal end partially integrated into and along a wall of the elongate member, the stabilization wire configured to bifurcate away from the elongate member at a transition point between the proximal end and the distal end of the elongate member, and the stabilization wire configured to exit the lower extremity vasculature via an ipsilateral percutaneous access.
A method for performing an endovascular procedure, the method comprising:
- inserting a guide sheath having a proximal and a distal end and an elongate member having a lumen therebetween via a contralateral percutaneous access into a lower extremity vasculature, the elongate member having a proximal and a distal end and comprising a stabilization wire partly integrated into and along a wall of the elongate member, a distal end of the stabilization wire bifurcating away from the elongate member at a transition point between the proximal end and the distal end of the elongate member;
- inserting a snare device via an ipsilateral access site into the lower extremity vasculature;
- capturing the distal end of the stabilization wire with the snare device;
- externalizing the stabilization wire at the ipsilateral access site and positioning the distal end of the elongate member within the lower extremity vasculature at or near the ipsilateral access site by applying a tensile force to the snare device and a push force to the guide sheath;
- reversibly anchoring the externalized stabilization wire at the ipsilateral access site.
