A system is described for performing vascular anastomosis without the use of sutures. The system includes a connector comprised of memory material and an incision seal. The connector has one end configured to securely engage a graft vessel and another end with wings and barbs. The wings are configured to securely engage an inner wall of a main vessel and the barbs are configured to lock with the incision seal. Once locked, the incision seal and the connector apply a clamping force that secures the graft vessel with the main vessel.

Sutureless vascular anastomosis connection

Techniques for sutureless vascular anastomosis are described, including an incision seal including a base configured to partially house an outer surface of a main vessel, the base being formed using a material that is configured to be penetrated by a barb disposed on a connector the main vessel being secured to the base when the base is at least partially pierced by the barb, an upper lumen configured to guide a graft vessel, and a housing opening configured to receive the graft vessel.

Techniques for sutureless vascular anastomosis are described, including a connector configured to provide fluid communication between a graft vessel and a main vessel, the connector having tines disposed circumferentially about an outer surface of the connector, a front wing coupled to the base, the front wing having a tine configured to engage an inner surface of the main vessel, and having a hinge coupling the front wing to the connector, and a rear wing coupled to the base, the rear wing having another tine configured to engage the inner surface of the main vessel, and having another hinge coupling the rear wing to the connector.

Techniques for sutureless vascular anastomosis are described, including a sutureless vascular anastomosis connector configured to couple a graft vessel to a main vessel, including a connector body configured to engage a main vessel when inserted into an opening in a wall of the main vessel, and a wing coupled to the connector body and formed using a memory material, the wing being configured to rotate about a transverse axis of the connector when a restraining force is removed from an exterior surface of the wing.

Techniques for sutureless vascular anastomosis are described, including a connector having a tip configured to be inserted into a graft vessel, a body having a tine configured to engage tissue associated with a graft vessel, and a base having a front wing, a rear wing, and a barb, each of the front wing, the rear wing, and the barb being formed integrally with the base using a memory material, wherein the front wing, the rear wing, and the barb deploy at one or more pre-determined angles when a restraining force is removed, the restraining force keeping the front wing, the rear wing, and the barb in substantially axial alignment with the body.

A non-deforming deflectable multi-lumen catheter with an outer jacket having a deflectable distal end portion, an eccentric pull wire lumen, coil and shim embedded therein. The deflectable distal portion optionally having one or more transaxial notches in the external surface of the outer jacket. A functional device is disposed within the lumen of an inner tube substantially coaxial with the outer jacket of the catheter. The distal tip of the functional device egressible from the distal tip of the catheter, and upon deflection, automatically aligns with the distal tip of the catheter and functional device.

A modular drug delivery system for use by cardiothoracic surgeons and interventional cardiologists for delivery of molecular and cellular therapies that target genes, molecules and peptides. The regulated drug delivery devices comprise a modular mechanically actuated drug delivery module (DDM) that can be attached to either a surgical viewing endoscope hand-piece or specialized catheter for interventional procedures. The DDM provides metering of drugs to treatment sites and allows for quick interchangeability with other component parts such as a viewing scope end portion for MIS or other surgical procedures or a flexible catheter shaft for percutaneous procedures.

A sutured staple, instrument and method are provided for constructing a graft-to-artery anastomosis and other soft tissue anastomoses, particularly by minimally invasive (or endoscopic) surgery. The sutured staple is comprised of a needle, pin, base and flange. The needle allows this surgical staple to be sewn through, for example, a graft and artery to be joined, and the pin, base and flange are formed to seal the graft and artery together between cooperating surfaces of the base and flange. The instrument holds the staple at its distal or working end, and controls in the handle allow application of the staple. The method employs the sutured staples and instrument to join soft tissues and to construct graft-to-artery anastomoses.

A surgical fastener in the form of a pinned retainer, instrument and method are provided for constructing a graft to artery anastomosis and other soft tissue anastomoses, particularly by minimally invasive (or endoscopic) surgery. The pinned retainer fastener is comprised of a needle and a retainer. The needle has a base, shaft and tip that allow this member to be sewn through, for example, a graft and artery to be joined. The retainer has an aperture to receive and securely engage the needle shaft to seal the graft and artery together between cooperating surfaces of the needle base and retainer. The instrument holds the needle and retainer at its distal or working end, and controls in the handle allow application of the retainer. The method employs the pinned retainer fasteners and instrument to join soft tissues and to construct graft to artery anastomoses.

A laser surgery device for performing laser myocardial revascularization procedures on a human heart comprises a hand-held body portion with a forwardly extending probe member with an enlarged head end assembly including a piercing tip. A movable fiber bundle connected to a laser source extends through the body portion and the probe member with its distal tip at the head end assembly. A control button on the body portion enables the device to move the distal tip forwardly from the head end, and selectable stop members are provided on the body portion to provide different travel distances for the optical fiber bundle during a procedure. The body portion has a rotatable nose-piece with an internal ratchet mechanism which enables the device user to rotate the probe member and its head end to a selected optimum position before commencing a procedure. The head end assembly includes an easily replaceable piercing member in combination with a concave disk having a yieldable liner for cushioning the head assembly contact with the patient's heart. The device is used with a TMR procedure wherein the epicardium is initially pierced to provide access to the myocardium for the distal tip of the fiber bundle which then emits laser pulses as it is moved through the myocardium.
