The core wire includes an engaging portion that extends from the outer component to engage the body vessel when the core wire is in the second position.
Claims25
A wire guide for percutaneous guidance within a body vessel, the wire guide comprising:
- an outer component percutaneously insertable in the body vessel;
- and
- a core wire slidably disposed in the outer component and movable relative to the outer component between a first position and a second position, the core wire including an engaging portion that extends from the outer component to engage the body vessel when the core wire is in the second position.
A wire guide for percutaneous guidance within a body vessel, the wire guide comprising:
- a proximal portion;
- a distal portion having an end portion configured to be inserted into a wall of the body vessel and a stop portion having an effective diameter substantially greater than a diameter of the end portion to resist insertion of the end portion into the wall beyond a maximum insertion distance;
- and
- a body portion extending between the proximal portion and the distal portion.
A method of anchoring a wire guide to a body vessel, the method comprising:
- inserting the wire guide into the body vessel;
- extending an engaging portion of the wire guide into an engaging position;
- and
- engaging a wall of the body vessel with the engaging portion to anchor the wire guide to the body vessel.
An assembly for percutaneous insertion within a body vessel, the assembly comprising:
- a wire guide including an outer component and a core wire slidably disposed within the outer component, wherein the core wire is movable relative to the outer component between a first position and a second position and wherein the core wire includes an engaging portion configured to extend from the outer component to engage the body vessel when the core wire is in the second position;
- and
- a catheter configured to receive the wire guide and to be advanced percutaneously within the body vessel.
