Abstract
A stent, shunt, or plug, for at least partial insertion into a patient, can include a deformable elongated tubular body including a proximal portion and a distal portion and defining a longitudinal lumen of the tubular body therebetween. The deformable elongated body can be capable of an expanded state and a collapsed state. The tubular body can include a sheath and a plurality of magnetizable or magnetic elements for providing magnetic repulsion, after being magnetically actuated, to maintain the tubular body to maintain the expanded state.
Claims22
A magnetically actuatable dilation device for at least partial insertion into a patient, the device comprising:
- a deformable elongated tubular body including a proximal portion and a distal portion and defining a longitudinal lumen of the tubular body therebetween, the deformable elongated body capable of an expanded state and a collapsed state,
- wherein the tubular body includes a sheath and a plurality of magnetizable or magnetic elements for providing magnetic repulsion, after being magnetically actuated, to maintain the tubular body to maintain the expanded state.
A stent, shunt, or plug device, for at least partial insertion into a patient, the device comprising:
- a deformable elongated tubular body including a proximal portion and a distal portion and defining a longitudinal lumen of the tubular body therebetween, the deformable elongated body capable of an expanded state and a collapsed state,
- wherein the tubular body includes a sheath and a plurality of magnetizable or magnetic elements for providing magnetic repulsion, after being magnetically actuated, to maintain the tubular body to maintain the expanded state;
- and
- a magnetic applicator.
A method of actuating a stent comprising:
- inserting, to a desired location, a collapsed elongated tubular body including a proximal portion and a distal portion and defining a collapsible longitudinal lumen of the tubular body therebetween, wherein the tubular body includes a plurality of magnetizable or magnetic elements;
- and
- actuating the plurality of magnetizable or magnetic elements to provide magnetic repulsion to encourage the tubular body to maintain a more expanded state.
A method of maintaining patency in a body lumen of a patient comprising:
- inserting, to a desired location, a collapsed elongated tubular body including a proximal portion and a distal portion and defining a collapsible longitudinal lumen of the tubular body therebetween, wherein the tubular body includes a plurality of magnetizable or magnetic elements;
- and
- actuating the plurality of magnetizable or magnetic elements to provide magnetic repulsion such that the tubular body is maintained in an expanded state conforming to walls of the body lumen, thereby maintaining patency in the body lumen.
