Abstract

A cardiac lead delivery device is disclosed which includes an elongated carrier body having opposed proximal and distal end portions and defining an interior channel for accommodating implantable cardiac leads, and an adjustable collar for securing the implantable cardiac leads within the interior channel of the carrier body during delivery to an implantation site.

Claims

1. A device for delivering implantable cardiac leads to an implantation site comprising:

a) an elongated carrier body having opposed proximal and distal end portions and defining an open interior channel having a generally U-shaped cross-section for accommodating at least one implantable cardiac lead, wherein the distal end portion of the carrier body is tapered to form a shroud to protect the distal end portion of the at least one cardiac lead and wherein the shroud is collapsible to reduce the profile thereof for removal from the implantation site; and

b) an adjustable collar mounted for movement along the carrier body for releasably securing the at least one implantable cardiac lead within the open interior channel of the carrier body during delivery to the implantation site.

2. A device as recited in claim 1, wherein the distal end portion of the carrier body includes electrically active mapping electrodes.

3. A device as recited in claim 1, wherein the distal end portion of the carrier body is adapted and configured for articulated movement.

4. A device as recited in claim 1, further comprising means operatively associated with the proximal end portion of the carrier body for effectuating articulated movement of the distal end portion of the carrier body.

5. A device as recited in claim 1, further comprising a journaled handle assembly for effectuating axial rotation of the carrier body.
