Flange stent device and modular stent system thereof

A modular stent system, comprising:

• a first stent that is substantially straight or tapered;
• and
• a flange stent coupled to the first stent, wherein the second stent comprises
• a body with a first end and a second end, and
• a flange at either the first end or the second end of the body, wherein the flange is approximately perpendicular to the axis of the body.

A method of deploying a flange stent, comprising:

• inserting a first stent into a first vessel, wherein the first stent comprises a body portion that is substantially straight or tapered;
• deploying a flange stent through a side wall of the first stent, wherein the flange stent comprises a body coupled to a flanged end;
• and
• positioning the flange stent proximate to a branching portion of the first vessel.

A method of deploying a flange stent, comprising:

• inserting a guide wire into a first vessel;
• inserting a catheter with a flange stent over the guide wire, wherein the flange stent comprises a body portion that is substantially straight and a flange portion on one end of the body portion;
• and
• positioning the flange stent proximate to a side branch of the first vessel.

A method of deploying a flange stent, comprising:

• inserting a catheter with a flange stent into a first vessel, wherein the catheter comprises a balloon,
• wherein the flange stent comprises a body portion that is substantially straight and a flange portion on a distal end of the body portion;
• positioning the body portion within a side branch of the first vessel;
• expanding the balloon;
• and
• positioning the flange portion of the flange stent adjacent to an orifice of the side branch by expanding the balloon.

A method for positioning a misdeployed flange stent, comprising:

• advancing a balloon catheter over a guide wire to a first position within a vessel proximate to a flange stent;
• positioning the balloon catheter in a first portion of the flange stent;
• inflating the balloon catheter to contact an inner surface of the flange stent;
• advancing the inflated balloon catheter distally over the guide wire to a second position within the vessel to cause movement of the first portion of the flange stent within the vessel;
• and
• removing the balloon catheter and guide wire.

A method of forming a flange stent, comprising:

• providing a stent template with a first section that is substantially straight and a second section that comprises a flange;
• weaving a plurality of strands around the first section and the second section of the template;
• and
• forming a stent that comprises a body portion and a flange portion with at least some of the plurality of strands.

A method of forming a flange stent, comprising:

• forming a substantially straight stent by weaving together a plurality of strands;
• providing a stent template with a first section that is substantially straight and a second section that comprises a flange;
• coupling the substantially straight stent to the stent template, wherein a first portion of the stent is coupled to the first section of the template and a second portion of the stent is coupled to the second section of the template;
• and
• heat treating a portion of the substantially straight stent to form a flange from the second portion of the stent.

A method of forming a flange stent, comprising:

• forming a substantially straight stent by weaving a plurality of strands over a stent template that is substantially straight, wherein the stent template comprises a first end and a second end;
• increasing a weave density of the plurality of strands proximate to one end of the stent template;
• and
• heat treating the plurality of strands woven over the stent template to form a flange portion of the stent.
