US 2014/0277091 A1 · DETACHABLE DELIVERY DEVICE

Abstract

A system for delivering an implantable medical device is provided including the medical device, a delivery wire that is rotationally coupled to the medical device, and a catheter. The delivery wire includes a spiraling marking extending around the delivery wire to provide visual confirmation that the wire is rotating. The medical device is delivered to a target site within a patient's body, and the delivery wire is rotated to release the medical device from the wire. Observation of the rotating spiral markings helps ensure that the medical device is being released from the wire. The rotational coupling between the delivery wire and the medical device limits the medical device from becoming unintentionally released, and allows for repositioning of the device within the body even after the device has been exposed from the catheter.

Dependent claims

A system for delivering a medical device to patient's body, the system comprising:

an elongate delivery wire having proximal and distal ends;
an implantable medical device having proximal and distal ends, the proximal end of the medical device releasably attached to the distal end of the delivery wire;
a rotatable connection releasably coupling the proximal end of the medical device to the distal end of the delivery wire, the rotatable connection being disengaged via rotation of the delivery wire relative to the medical device;
and
a spiraling marking disposed along at least a portion of the delivery wire for indicating rotation of the wire.
