ABSTRACT:
The present invention relates to an apparatus for removal of a clot from a blood vessel comprising, an embolectomy catheter, one or more sheath introducers disposed within the embolectomy catheter, two removal devices moveably engaged within the sheath introducers, and a balloon catheter with an inflatable/deflatable balloon. Each removal device has a flexible rod and a racquet shaped head integral therewith. Each head has an attached basket for retaining the clot. Each head also has a wire extending from its distal end to the proximal end of the flexible rod for manipulation of the head during capture of the clot.
The invention also relates to a method for removing a clot from a blood vessel comprising the steps of: pre-loading two removal devices; one into each of two sheath introducers; pre-loading the two sheath introducers into an embolectomy catheter; making an incision for insertion of a guide wire into the right jugular vein; inserting the guide wire into the right jugular vein under an image amplifier; passing the guide wire into the pulmonary artery; inserting the pre-loaded embolectomy catheter into the jugular vein and passing the catheter over the guide wire to a point within the pulmonary artery proximate the clot; pushing the removal devices through a distal opening of the two sheath introducers and further through a distal opening of the embolectomy catheter; moving the removal devices toward the clot; capturing the clot between the removal devices; withdrawing the removal devices and the clot into the embolectomy catheter; and removing the embolectomy catheter from the vessel.
