Devices, systems, and methods are provided for accessing the interior of the heart and performing procedures therein while the heart is beating. In one embodiment, a tubular access device having an inner lumen is provided for positioning through a penetration in a muscular wall of the heart, the access device having a means for sealing within the penetration to inhibit leakage of blood through the penetration. The sealing means may comprise a balloon or flange on the access device, or a suture placed in the heart wall to gather the heart tissue against the access device. An obturator is removably positionable in the inner lumen of the access device, the obturator having a cutting means at its distal end for penetrating the muscular wall of the heart. The access device is preferably positioned through an intercostal space and through the muscular wall of the heart. Elongated instruments may be introduced through the tubular access device into an interior chamber of the heart to perform procedures such as septal defect repair and electrophysiological mapping and ablation. A method of septal defect repair includes positioning a tubular access device percutaneously through an intercostal space and through a penetration in a muscular wall of the heart, passing one or more instruments through an inner lumen of the tubular access device into an interior chamber of the heart, and using the instruments to close the septal defect. Devices and methods for closing the septal defect with either sutures or with patch-type devices are disclosed.

Devices and methods for port-access multivessel coronary artery bypass surgery
InactiveUS6478029B1Reduce oxygen demandReduce the temperatureSuture equipmentsDiagnosticsDiseaseSurgical approach
Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median sternotomy or other gross thoracotomy to expose the patient's heart, post-access CABG surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and / or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques. Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through a cardioscopic microscope inserted through an intercostal access port. Retraction instruments are provided to manipulate the heart within the closed chest of the patient to expose each of the coronary arteries for visualization and anastomosis. Disclosed are a tunneler and an articulated tunneling grasper for rerouting the graft vessels, and a finger-like retractor, a suction cup retractor, a snare retractor and a loop retractor for manipulating the heart. Also disclosed is a port-access topical cooling device for improving myocardial protection during the port-access CABG procedure. An alternate surgical approach using an anterior mediastinotomy is also described.

The invention provides devices and methods for performing less-invasive surgical procedures within an organ or vessel. In an exemplary embodiment, the invention provides a method of closed-chest surgical intervention within an internal cavity of a patient's heart or great vessel. According to the method, the patient's heart is arrested and cardiopulmonary bypass is established. A scope extending through a percutaneous intercostal penetration in the patient's chest is used to view an internal portion of the patient's chest. An internal penetration is formed in a wall of the heart or great vessel using cutting means introduced through a percutaneous penetration in an intercostal space in the patient's chest. An interventional tool is then introduced, usually through a cannula positioned in a percutaneous intercostal penetration. The interventional tool is inserted through the internal penetration in the heart or great vessel to perform a surgical procedure within the internal cavity under visualization by means of the scope. In a preferred embodiment, a cutting tool is introduced into the patient's left atrium from a right portion of the patient's chest to remove the patient's mitral valve. A replacement valve is then introduced through an intercostal space in the right portion of the chest and through the internal penetration in the heart, and the replacement valve is attached in the mitral valve position.

Method and apparatus to produce ultrasonic images using multiple apertures

A combination of an ultrasonic scanner and an omnidirectional receive transducer for producing a two-dimensional image from the echoes received by the single omnidirectional transducer is described. Two-dimensional images with different noise components can be constructed from the echoes received by additional transducers. These can be combined to produce images with better signal to noise ratios and lateral resolution. Also disclosed is a method based on information content to compensate for the different delays for different paths through intervening tissue is described. Specular reflections are attenuated by using even a single omnidirectional receiver displaced from the insonifying probe. The disclosed techniques have broad application in medical imaging but are ideally suited to multi-aperture cardiac imaging using two or more intercostal spaces. Since lateral resolution is determined primarily by the aperture defined by the end elements, it is not necessary to fill the entire aperture with equally spaced elements. In fact, gaps can be left to accommodate spanning a patient's ribs, or simply to reduce the cost of the large aperture array. Multiple slices using these methods can be combined to form three-dimensional images.

Progressive biventricular diastolic support device
InactiveUS7468029B1Easy accessIncrease acceptanceHeart valvesIntravenous devicesAtrial cavityLeft anterior axillary line
A device is proposed to progressively reduce the hemodynamic cardiac symptoms of congestive heart failure as well as those induced by dilated cardiomyopathies. This device affords progressive diastolic ventricular control by offering a method for percutaneous access and adjustments of its gas filled bladders surrounding the heart. After opening the pericardium, the device is not attached to the heart muscle but may be anchored to the pericardial sac. The device actually extends primarily around the heart from below the atrio-ventricular canal to the cardiac apex. Between the device exterior, made of non-elastic material and the epicardium, two independent elastic bladders or chambers provide variable compressive diastolic support to the right and left ventricles, while allowing adequate blood flow to the anterior and posterior descending epicardial branches of the coronary arteries and veins. Progressive hemodynamic increases in diastolic pressures for the right and left ventricles can be individually and repeatedly monitored by pressure gauges and an inert gas separately injected or removed in the enclosed chest through self-sealing access ports. These ports are subcutaneously implanted in the left anterior axillary line and connected by thin tubes across the 4th or 5th intercostal spaces to the pericardial bladders or chambers described above.
