Abstract: The present invention relates to a transmyocardial implant placement device with an introducer, a transmyocardial implant mounted about the introducer, a wound closure clip engaged to the introducer adjacent the transmyocardial implant. The introducer is adapted to be inserted through a lumen of a coronary vessel and a myocardium of a patient into a chamber of the patient's heart and form a blood flow pathway through the myocardium between the heart chamber and the coronary vessel. When the introducer is inserted, the wound closure clip engages an outer wall of the coronary vessel and the transmyocardial implant extends from the heart chamber to the lumen of the coronary vessel. The transmyocardial implant is expanded in the blood flow pathway and the introducer retracted, leaving the transmyocardial implant in the within the blood flow pathway.

Abstract: A method for performing a bypass procedure utilizes the patient's vascular system for accessing or reaching a desired location within the patient's body. The method may also provide a direct flow path from a heart chamber to a coronary vessel via a septal passageway.

Abstract: A vascular implant includes a scaffold and a tubing in covering relating to the scaffold. Preferably, the tubing completely covers or encases the scaffold interior surface and exterior surface to leave no portion of the scaffold exposed. Methods for constructing includes pulling tubing through a scaffold and folding at least a portion of the tubing over at least one of the ends of the scaffold. Methods for using an implant include performing coronary vessel bypass procedures or forming blood flow paths in a blood vessel utilizing constructions described herein.

Abstract: An attachment member for securing a graft material to a vessel includes a conduit portion for attachment to the graft material. The attachment member has first and second anchor wings formed on opposite sides of an end of the conduit portion. The anchor wings are biased to extend substantially perpendicular to an axis of the conduit portion. The first and second anchor wings have arcuate shapes around substantially collinear axes for the anchor wings to define a flow path within a vessel on opposite sides of the conduit portion.

Abstract: A transmyocardial implant delivery system is disclosed for establishing a blood flow path through a myocardium between a heart chamber and a lumen of a coronary vessel residing on an exterior of the heart. The transmyocardial implant delivery assembly includes as conduit for defining a blood flow path, a temporary sheath, and a tool holding a second end of the conduit. The conduit includes a rigid portion adapted to be inserted into and retained within the heart wall of a heart chamber. The rigid conduit is sufficiently rigid to withstand collapsing in response to contraction forces of the heart wall. The conduit also includes a synthetic flexible portion that is in fluid communication with the rigid portion. An end of the flexible portion corresponding to the second end of the conduit is sized to be received in a lumen of a coronary vessel. The transmyocardial implant delivery system is inserted through the heart wall.

Abstract: The present invention relates to a medical device including two parallel tubes attached to each other, one of which is shorter in length and receives a guide snare for directing the path of the catheter within a patient's blood vessels and into the patient's heart. The present invention further relates to a method of using a catheter comprising two tubes, whereby a guide snare is anchored to a shunt within a patient's heart and extends out of the patient's body, one of the tubes of the catheter being placed about the guide snare and the catheter being advanced into the patient's heart along the guide snare.

Abstract: A transmyocardial implant includes a hollow rigid conduit adapted to be inserted into and retained within the heart wall of a heart chamber. The rigid conduit is sufficiently rigid to withstand collapsing in response to contraction forces of the heart wall. A synthetic flexible conduit has a first end secured to the conduit. The flexible conduit is blood compatible. A second end of the flexible conduit is secured to the coronary vessel. The rigid conduit and the flexible conduit define a blood flow path from the heart chamber to the coronary vessel. The flexible conduit is bonded to and wrapped around the rigid conduit for the blood flow path to be defined by an uninterrupted surface of the flexible conduit.

Abstract: An anastomosis device for securing a biocompatible conduit to a blood vessel. The conduit includes a first end and a second end. A resilient flange is positioned at the second end. The flange is movable between an expanded orientation and a compressed orientation and biased toward the expanded orientation. When the flange is compressed, it is adapted for insertion through an incision in a blood vessel. When the compression is released, the flange returns to its expanded orientation. The first end is adapted to be inserted into and retained within another anatomical structure creating an anastomosis between the blood vessel and the anatomical structure via the conduit. Other anatomical structures specifically include the heart wall of a heart chamber.

Abstract: A method for performing a coronary artery bypass procedure is disclosed. The method of the present disclosure is preferably utilized where the patient's vascular system is used as a conduit for accessing or reaching a desired location within the patient's body. Furthermore, the method also provides a direct flow path from a heart chamber to the coronary artery.
