Abstract

An interventional radiologic device for removal of an embedded filter is provided. The device distinguishes a laser sheath with optical fibers for applying ablation energy to tissue. A removable introducer is movable within the lumen of the laser sheath and has at least two open channels to run wires. One or more sheath detachable modular adapters are used for providing ablation energy, force sensing and/or preventing bleeding. The distal open end of the laser sheath is preferably beveled with an angle up to 45 degrees. In one aspect, the introducer has a bulb-like tip, which fits against the distal end the laser sheath, yet can still be removed from the laser sheath via its proximal end. This device can be inserted over two wires simultaneously thereby allowing insertion over a wire loop configuration used to engage the apex of embedded IVC filters.
