Abstract
The present disclosure describes treatment of the vasculature of a patient with an expandable implant. The implant is constrained to a reduced delivery diameter for delivery within the vasculature by at least one sleeve. The implant can be constrained to other diameters, such as an intermediate diameter. The sleeves can be expanded, allowing for expansion of the diameter of the expandable implant, by disengaging a coupling member from the sleeve or sleeves from outside of the body of the patient. The expandable implant can comprise a steering line or lines which facilitate bending and steering of the expandable implant through the vasculature of a patient.
Claims15
A catheter assembly comprising:
- a catheter having a leading end and a trailing end and comprising a main lumen extending between the leading end and the trailing end;
- an expandable medical device positioned at the leading end of the catheter;
- a plurality of steering lines configured to selectively bend the expandable medical device, the plurality of steering lines positioned to traverse a surface of the expandable medical device such that, across at least a portion of the expandable medical device, the plurality of steering lines are parallel to and are spaced less than ninety degrees from each other about a circumference of the expandable medical device.
A catheter assembly comprising:
- a catheter having a leading end and a trailing end and comprising a main lumen extending between the leading end and the trailing end;
- an expandable medical device positioned at the leading end of the catheter;
- and
- a plurality of steering lines configured to selectively bend the expandable medical device, the plurality of steering lines positioned to traverse a surface of the expandable medical device such that, across at least a portion of the expandable medical device, the plurality of steering lines are parallel to and circumferentially adjacent each other, wherein the plurality of steering lines are woven through the surface of the expandable medical device.
A catheter assembly comprising:
- a catheter having a leading end and a trailing end and comprising a main lumen extending between the leading end and the trailing end;
- an expandable medical device positioned at the leading end of the catheter;
- and
- a plurality of steering lines configured to selectively bend the expandable medical device, the plurality of steering lines positioned to traverse a surface of the expandable medical device such that, across at least a portion of the expandable medical device, the plurality of steering lines are parallel to circumferentially adjacent each other;
- wherein at least a portion of the plurality of steering lines extends through a portion of the main lumen;
- wherein the plurality of steering lines exit the catheter and are engaged with the expandable medical device near a proximal end of the expandable medical device,
- wherein the plurality of steering lines may extend across and remain substantially in contact with the surface of the expandable medical device from the proximal end to a distal end of the expandable medical device.
