Abstract
A medical pacing wire comprising a clamp that is adapted to be moved between an open position and a closed position and further adapted to allow a user to attach an electrode to a living tissue. In particular embodiments, the medical pacing wire may include a memory shape alloy having a memory state, which is adapted to cause the clamp to move from the closed position toward the open position when the memory shape alloy is caused to move from a non-memory state to the memory state. Also, in some embodiments, the clamp may comprise a superelastic material, and the medical pacing wire may be adapted to allow a user to remotely cause the clamp to substantially release the living tissue that has been closed within the clamp without substantially damaging the living tissue.
Claims25
A medical pacing wire comprising:
- an elongated flexible conductor;
- and
- a clamp comprising first and second opposing clamp members, said clamp being adapted to be moved between:
- (A) an open position in which said first and second clamp members are spaced a first distance apart from each other;
- and
- (B) a closed position in which said first and second clamp members are spaced a second distance apart from each other, said second distance being shorter than said first distance, wherein:
- said medical pacing wire is adapted to allow a user to attach an electrode to a living tissue by:
- (A) moving said clamp into said open position;
- (B) positioning said clamp so that said living tissue is positioned between said clamp's first and second opposing clamp portions;
- (C) closing said clamp until said first and second clamp portions:
- (i) are in said closed position, and
- (ii) exert opposing compressive forces on opposite sides of said living tissue and thereby maintain said electrode in engagement with said living tissue;
- and
- said medical pacing wire is adapted to allow a user to pace the living tissue by, while said clamp is maintaining said electrode in engagement with said living tissue, conveying an electrical current through said conductor, into said electrode, and into said living tissue;
- and
- said medical pacing wire is adapted to allow a user to remotely cause said clamp to at least substantially release said living tissue.
A medical pacing wire comprising:
- an elongated flexible conductor;
- a superelastic clamp comprising first and second opposing clamp members, said clamp being adapted to be moved between:
- (A) an open position in which said first and second clamp members are spaced a first distance apart from each other;
- and
- (B) a closed position in which said first and second clamp members are spaced a second distance apart from each other, said second distance being shorter than said first distance, wherein, when said superelastic clamp is in its memory state, said superelastic clamp is in said closed position;
- and
- a memory shape alloy that is attached in mechanical communication with said clamp so that causing said memory shape alloy to move from a non-memory state of said memory shape alloy to a memory state of said memory shape alloy causes said clamp to move from said closed position toward said open position.
A medical pacing wire comprising:
- an elongated flexible conductor;
- a superelastic clamp comprising first and second opposing clamp members, said clamp being adapted to be moved between:
- (A) an open position in which said first and second clamp members are spaced a first distance apart from each other;
- and
- (B) a closed position in which said first and second clamp members are spaced a second distance apart from each other, said second distance being shorter than said first distance, wherein, when said superelastic clamp is in its memory state, said superelastic clamp is in said open position;
- and
- a memory shape alloy that is attached in mechanical communication with said clamp so that causing said memory shape alloy to move from a non-memory state of said memory shape alloy to a memory state of said memory shape alloy causes said clamp to move from said open position toward said closed position.
