Surgical devices for stabilizing the heart are disclosed which facilitate anastomosis under beating heart conditions. Various instruments or devices may be maneuvered and secured on a retractor device to provide stabilization of the heart. An instrument mount is provided which is preferably configured to accept a surgical instrument, such as a tissue stabilizer, and to allow the instrument to be easily maneuvered to a desired position and subsequently locked into position with a simple operation of a single locking actuator. Further disclosed are stabilizer devices each having at least one surface for contacting the heart and each being adapted to be mounted to the retractor while having the ability to be positioned in the desired location against the heart.

Surgical instruments for accessing and stabilizing a localized portion of a beating heart

Surgical devices for stabilizing the heart which facilitate anastomosis under beating heart conditions. Various instruments or devices may be maneuvered and secured on a retractor device to provide stabilization of the heart. An instrument mount is provided which is preferably configured to accept a surgical instrument, such as a tissue stabilizer, and to allow the instrument to be easily maneuvered to a desired position and subsequently locked into position. Stabilizer devices each having at least one surface for contacting the heart and each being adapted to be mounted to the retractor while having the ability to be positioned in the desired location against the heart are provided.

In accordance with the present invention, there is disclosed surgical methods and apparatus for accessing and stabilizing the heart. The methods and apparatus facilitate access to an anastomosis site, allows various instruments or devices to be maneuvered and secured in place, and provide stabilization of the heart. The apparatus may involve a tissue stabilizer, and in particular a tissue stabilizer for use in immobilizing or stabilizing a portion of the beating heart using a compressive force delivered to the heart via the tissue stabilizer. The stabilizer may include a stabilizer base and a shaft. The shaft may be secured within an appropriate instrument mount preferably fixed to a retractor or other stable platform as disclosed herein. The stabilizers of the present invention provide improved access to a surgical site at a target vessel on the surface of the heart and may include features which facilitate optimal presentation of the target vessel.

Surgical instruments and procedures for stabilizing a localized portion of a beating heart

An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is preferably pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.

Access platform for internal mammary dissection

A device for occlusion of a body passageway and subsequent perfusion of the body passageway with arterial return blood, cardioplegia and other fluid is disclosed. The device of the present invention is an expandable cannula comprising a flexible, expandable tubular elongate body having a first diameter and a second diameter, wherein the expandable cannula is inserted having a first diameter and then expanded to a second diameter to provide perfusion flow to the body passageway through at least one arterial return aperture provided on the distal end of the expandable tubular elongate body in fluid communication with a perfusion lumen provided within the cannula. The device may be further provided with one or more additional lumens for providing additional functions to the vessel lumen and may also include an expandable occluding member fixed at the distal end of the cannula for isolating the surgical area from the rest of the arterial system. A preferred method of use of the present invention is also disclosed wherein having a first diameter is inserted endovascularly into the vessel of a patient and advanced to a point of interest. At the point of interest, the device is expanded to a second diameter and perfusion flow to the vessel lumen is provided. Following the performance of a surgical procedure, perfusion flow is terminated and the device is removed from the vessel.

Expandable cannula for performing cardiopulmonary bypass and method for using same

Methods and devices for revascularization of a patient's coronary artery system which obviate the need to place the patient on cardiopulmonary bypass. A method is provided for revascularizing a patient while the-heart is beating, and includes performing at least one minimally invasive coronary artery bypass graft procedure, or other cardiac surgical procedure, and contemporaneously performing at least one catheter-based procedure in at least one coronary artery. The catheter-based procedure(s) may be either therapeutic or diagnostic or both, and may involve delivering at least one catheter to a coronary artery via a surgical or percutaneous opening in the thoracic cavity or via a percutaneous opening at a location peripheral to the thoracic cavity. The catheter-based procedure or procedures is performed contemporaneously with the bypass graft procedure, and specifically prior to, during, or after anesthetizing the patient for purposes of the bypass graft procedure. An arterial access device is also provided for central cannulation and direct intraoperative catheterization of a patient's coronary artery system on a beating heart. The device includes a tubular member, such as a cannula, having a proximal end and a distal end, and an elongated puncturing member, such as a trocar, which is slideably disposed within the tubular member. The puncturing member has a sharp distal end for puncturing through the wall of a coronary lumen. The arterial access device further includes a sealing member for engaging the coronary lumen wall at the puncture site in order to minimize the leakage of blood from the puncture site.

Methods and devices for minimally invasive coronary artery

An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and support pads interconnected to the first blade. A torsional member is operably interconnected to the first blade and the spreader member and is used to vertically displace the first blade in either direction and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor interconnected to the blades is used to draw the soft tissue around an incision away from the surgeon's working area.
