A method and apparatus for performing mitral valve chordal repair on a patient include attaching at least one filament to a mitral valve leaflet and to a papillary muscle. A first end of a filament can be attached to the mitral valve leaflet and the length of the filament can be adjusted by adjusting the tension of the filament in a catheter. The second end of the filament can be attached to an attachment site.

Method and apparatus for repairing or replacing chordae tendinae

A method of surgery including bending a multi-purpose surgical implement handle that has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section. The method includes attaching a surgical implement to the attaching section of the handle, and bending the adjusting section at least once prior to inserting the implement through a surgical opening to a surgical field. The method further may include bending the adjusting section more than once to form multiple bends therein.

Method of surgery including adjusting the shape of an implement handle

A surgical knife which provides improved multi-sided incisions and is preferably allows for a substantially cruciate, or cross-shaped incision. The surgical knife includes a handle and a multi-bladed portion located at one end of the handle. The handle is sized and configured to maximize grip and surgical manipulation thereof. The multi-bladed portion is formed from a primary blade and a secondary blade. The primary blade is configured with two exemplary primary blade members. The primary blade members are formed with sharpened edges which combined to form a sharpened distal point of the primary blade. The secondary blade is formed with sharpened edges and cooperates with the primary blade. The coupling of the primary blade and the secondary blade is such that the distal end of the secondary blade is located at a distance from the sharpened distal point of the primary blade. The combination of the primary and secondary blades form a multi-bladed portion which creates an improved, more precise and easier to control incision in a biological tissue. The surgical knife is especially useful, for example, in improved aortotomies.

Apparatus and method for improved aortic incision

A catheter system for use in minimally invasive cardiac surgical procedures. The catheter system diminishes certain trauma generally associated with invasive cardiac procedures while providing aortic occlusion, extracorporeal circulation, cardiac arrest, and cardiac venting. The catheter system provides a minimally invasive and simplified system that performs total cardiopulmonary bypass with ease of insertion, improved whole body profusion, and shortened recovery periods. The catheters are refined, with reduced diameters and specialized functions for maximum control of each aspect of cardiopulmonary bypass.

Cardiopulmonary catheter system

A multi-purpose surgical implement handle has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section.

Shape-adjustable surgical implement handle

An aortic knife which provides multi-sided incisions within an aorta for effectuating improved aortotomies. The aortic knife includes a handle and multiple blades radiating from the handle. The handle is sized and configured to maximize grip and surgical manipulation thereof. The multiple blades radiate outwardly and proximally from a distal sharpened point. A substantially cruciate, or cross-shaped, incision results from four sharpened blades extending from the distal sharpened point. Alternatively, the multi-bladed configuration of the aortic knife may comprise three, five, or six or more blades. The blades form equal angles in radiation outwardly and proximally from the distal sharpened point. The method of the invention requires obtaining an appropriately sized aortic knife which is stabbed into a portion of an aorta. An anvil of an aortic punch is then inserted into the incision in the aorta without the stretching necessitated by the conventional single linear incision. The punch is then centered and fired; the resulting aortotomy lacks the lateral nicks associated with the prior art. Alternatively, the knife may be used for cannulation of a vessel.

The present invention is directed to new and useful methods and apparatus for isolating and immobilizing tissue for improved presentation in a surgical site, preferably in coronary bypass on a beating heart. At the same time, the present invention also helps avert ischemic damage to tissues downstream. A surgical stabilizer in accordance with the present invention offers physical manipulation of a surgical site, which improves the surgeon's sewing, grasping, and visualizing abilities at the site, and in turn, may increase the confidence and patency of the graft. The stabilizer is used to compress or to suction a region of the heart just below a stenotic coronary artery. The surgeon may selectively articulate the tissue by spreading it apart or pushing it together, as per his or her preference, or per the requirements of the surgical situation. The surgeon may lock in place the handle via a ratchet mechanism to hold the specific open or closed articulation of the surgical stabilizer. With the tissue thus isolated and immobilized, the surgeon may then graft the bypass vessel distal to the stenosis in the coronary artery.

Surgical stabilizer and method for isolating and immobilizing cardiac

The present invention is directed to new and useful methods and apparatus for improving access to the heart during cardiac surgery, while avoiding damage to the phrenic nerves. The present invention comprises a heart elevation apparatus which is soft and substantially cylindrical, with substantially flat anterior and posterior surfaces. Upon inflation, the anterior surface stabilizes the positioning of the heart and prevents the heart from falling off of the apparatus. The flat posterior surface facilitates positioning of the apparatus on the chest wall. An insulation pad on the posterior surface serves to insulate the phrenic nerves from the frigid bathes commonly employed in cardiac surgical procedures, and also protects the nerves from any compressive forces exerted during the surgery. A web member in the interior of the inflatable chamber prevents the inflatable chamber from blowing up into a ball, and instead constrains the anterior and posterior surfaces, thus resulting in flat or concave appearance, depending on the level of inflation in the inflation chamber. Insertion and proper placement of the apparatus in a deflated state is preferably through an incision in the thoracic wall or through an opening in the sternum. The apparatus is positioned beneath the heart along the chest wall, such that the heart balances stably thereon. The apparatus is then selectively inflated, which elevates the heart and improves the surgeons access thereto. After completion of the cardiac surgical procedure, the apparatus is deflated and then removed from the patient.

Inflatable heart elevation apparatus and method

An endoscope has a fiber optic image bundle which is insertible into a separate sterile sleeve such that the fiber optic image bundle need not be sterilized prior to use. A window formed proximate the distal end of the sleeve facilitates viewing through the fiber optic image bundle. A contractile member urges the fiber optic image bundle into abutment with the window to facilitate proper optical alignment of the distal end of the fiber optic image bundle with the window.

Endoscope with sterile sleeve

An endoscope having a proximal end and a distal end includes a housing disposed at the proximal end and a probe attached to the housing and extending along an axis to the distal end of the endoscope. The probe has a wall with an outer surface and an inner surface which defines a lumen extending along an axis from the housing to the distal end of the endoscope. At least a portion of the wall includes an outer surface with a tapered shape in axial cross-section and a non-circular shape in radial cross-section.
