초록 ▼

A cardiac lead has an electrode and fixation assembly including a plurality of fixation members movable to extended positions into heart tissue to retain the electrode in intimate engagement with heart tissue. An elongated stylet is used to move the fixation members to their extended positions into the heart tissue and retract the fixation members into the fixation assembly to allow the lead to be removed from the heart and body of a person.

대표청구항 ▼

An implantable lead comprising: an electrical conductor having a first end adapted to be connected to a cardiac arrhythmia management device and a second end, a sheath of insulative material covering said conductor, and an electrode and fixation assembly connected to the second end of the conductor and the sheath, said electrode and fixation assembly including a body having a chamber, said body being an electrical conductor member connected to the electrical conductor, said body having a distal end including and outer surface for directly containing the endocardium of the heart, a jacket of electrical insulation material covering the body except for said outer surface, carrier means located within the chamber for movement between first and second positions; at least one fixation means moveable from a first position within the assembly to a second position extended away from the assembly for engagement with the endocardium of the human heart, means mounting said fixation means on the carrier means whereby the fixation means moves with the carrier means, said body and jacket having hole means open to the chamber accommodating the fixation means to allow the fixation means to be moved from the chamber outwardly of the body into the endocardium of the heart and moved inwardly into the body out of engagement with the endocardium of the heart, said carrier means cooperating with means operable to selectively move the carrier means to the first and second positions to extend and retract the fixation means relative to the body.
