Abstract
Described are devices, methods and systems useful for achieving occlusion of vascular vessels. Percutaneous procedures can be used to occlude and obliterate the greater saphenous vein, for example in the treatment of varicose vein condition caused by venous reflux. Certain embodiments encompass the percutaneous delivery of an occlusion device inverted within a cannula, its deployment and filling, so as to occlude or obliterate a portion of a vascular vessel.
Claims51
A method for occluding a portion of the vasculature, comprising:
- providing access to the vasculature;
- providing a balloon including a remodelable material, wherein at least a portion of the balloon is inverted;
- providing a cannulated device, wherein a lumen of the cannulated device is in communication with the balloon;
- delivering the balloon and device to a site within the vasculature;
- and
- locating the balloon in the vasculature after delivery so as to cause occlusion of the vasculature.
A method for treating a venous dysfunction in a leg of a patient, comprising:
- providing a percutaneous access to a venous vessel;
- providing a cannulated device having a lumen, a proximal end, and a distal end and an inflatable occlusion device having a proximal end and a distal end, wherein at least a portion of the inflatable occlusion device is received within the lumen of the cannulated device;
- delivering the cannulated device containing at least a portion of the inflatable occlusion device through the percutaneous access to a site within the venous vessel;
- and
- passing fill material into the inflatable occlusion device after delivery so as to occlude the venous vessel.
A method for occluding a vascular vessel, comprising:
- providing a cannulated device having a proximal end, a distal end, and a lumen, wherein the lumen is in communication with the interior of an at least partially inverted balloon that includes a remodelable material and has a proximal end and a distal end;
- locating the balloon and cannulated device at a site within the vascular vessel;
- positioning the distal end of the balloon within the vascular vessel after locating the balloon and cannulated device within the vessel;
- and
- passing fill material into the balloon.
A method for treating a venous dysfunction in a leg of a human, comprising:
- providing a device, the device having a proximal end, a distal end, and a lumen, wherein the device lumen is in communication with an at least partially inverted fillable member, the fillable member further having a proximal end and a distal end;
- providing a percutaneous access to a saphenous vein of the leg;
- locating the at least partially inverted member and device within the saphenous vein through the percutaneous access;
- locating the distal end of the fillable member in the saphenous vein after locating the member and device within the saphenous vein;
- and
- expanding the member in the saphenous vein after locating the distal end of the member in the vein, so as to cause occlusion of the saphenous vein.
The method of 24, wherein expanding the fillable member occurs on at least two occasions.
A method for occluding a portion of the vasculature, comprising:
- locating an inverted balloon within the vasculature, wherein the inverted balloon is in communication with a lumen of a cannulated device;
- and
- passing fill material through the cannulated device lumen into the balloon after the balloon is located within the vasculature.
A method for delivering a balloon to a site within a vascular vessel, comprising:
- providing a cannulated device having a proximal end, a distal end, and a lumen and an elongate balloon having a proximal end, a body, and a distal end, wherein the interior of the balloon is in communication with the device lumen and the elongate balloon is at least partially inverted;
- providing access to the vascular vessel;
- locating the cannulated device and the at least partially inverted balloon at the site;
- and
- deploying the balloon into the vascular vessel.
A medical kit for occluding a portion of the vasculature, comprising:
- a balloon including a remodelable material and having a proximal end and a distal end, wherein said proximal balloon end is attached to the distal end of a cannulated device and at least a portion of said balloon is received within the lumen of the cannulated device;
- and
- a sheath configured for slidably receiving the cannulated device and balloon.
A method for increasing the packing density of a balloon, comprising folding the balloon in a controlled fashion, so as to reduce the diameter of a percutaneous balloon delivery system.
A medical device for occluding a bodily lumen, comprising:
- a cannulated device having a lumen, a proximal end, and a distal end, said cannulated device further comprising a balloon, wherein at least a portion of said balloon is inverted and said balloon is in communication with said lumen of said cannulated device.
A medical device for occluding a bodily lumen, comprising a balloon, said balloon having a proximal end and a distal end, wherein at least a portion of said balloon occupies an inverted position.
A medical product, comprising:
- an elongate occlusion device, said elongate occlusion device having a proximal end and a distal end, wherein at least a portion of said elongate occlusion device is inverted.
A method for treating a vascular vessel, comprising:
- providing a fillable member, wherein at least a portion of said fillable member is in an inverted configuration;
- providing access to a vascular vessel with a cannulated device, the cannulated device having a proximal end, a distal end, and a lumen;
- locating at least a portion of the fillable member within a vascular vessel by passing the member through the lumen.
