Abstract
The present disclosure is directed, in one embodiment, to a wire centering sheath system in which wires outwardly extend from a sheath to brace against a vessel wall. The wire centering sheath system may be used to center endovascular devices.
Claims20
A wire centering sheath device comprising:
- (a) a shaft, the shaft having a proximal end, a distal end, a sidewall, at least two slots forming at least two voids in the sidewall, and at least two centering wires connected to the shaft and disposed adjacent to the at least two slots, wherein the shaft includes a shaft inner lumen running from the proximal end to the distal end;
- (b) a rod adapted for inserting into the proximal end of the shaft, the rod having a distal end configured to engage within the shaft inner lumen and urge the at least two centering wires to extend into the at least two voids, wherein the centering wires contact a body channel when the wire centering sheath device is inserted into the body channel.
A method of centering a wire centering sheath device within a body channel comprising:
- (a) preparing a body channel to receive a wire centering sheath device;
- (b) inserting a wire centering sheath device within a body channel, the device comprising a shaft, the shaft having a proximal end, a distal end, a sidewall, at least two slots forming at least two voids in the sidewall, and at least two centering wires connected to the shaft and disposed adjacent to the at least two slots, wherein the shaft includes a shaft inner lumen running from the proximal end to the distal end;
- and a rod adapted for inserting into the proximal end of the shaft, the rod having a distal end configured to engage within the shaft inner lumen;
- (c) deploying the at least two centering wires by axially moving the rod within the shaft inner lumen so as to contact the at least two centering wires and urge the at least two centering wires to extend into the at least two voids and contact the body channel, wherein the wire centering sheath device is centered within the body channel.
1 more element
A wire centering sheath system comprising:
- a shaft, the shaft having a proximal end, a distal end, a sidewall, an interior surface, at least three slots forming at least three voids in the sidewall, the at least three slots and at least three voids disposed at substantially equal radii of the longitudinal axis of the shaft, and at least three centering wires connected to the interior surface and disposed adjacent to the at least three slots, wherein the shaft includes an inner lumen running from the proximal end to the distal end;
- a rod adapted for inserting into the proximal end of the shaft, the rod having a distal end configured to engage within the inner lumen and urge the at least three centering wires to extend into the at least three voids, wherein the rod further comprises a rod inner lumen configured to enable insertion of a medical instrument into the rod inner lumen;
- wherein the centering wires contact a body channel when the wire centering sheath device is inserted into the body channel.
