Embodiment Construction

[0053] Detailed Description of Preferred Embodiments

[0054] In a preferred embodiment of the invention, a surgeon implants a prosthetic heart valve over the existing, often calcified, propria leaflets. Procedures and devices exist to remove calcified lobules, and the attendant risks—including release of calcified material into the bloodstream—are unimportant. Therefore, a heart valve replacement operation in which an artificial heart valve is directly attached to the proper leaflets and accommodates the proper leaflets is preferable.

[0055] An exemplary embodiment of channel entry stabilizer 20 is shown in Figure 1-8 Among them, it mainly includes a base 22, an articulated arm 24 connected thereto, and a stabilizing sleeve 26 connected to the arm opposite the base. Base 22 provides a structural brace adapted to be held by or adjacent to existing anchors in the surgical field, while sheath 26 is compatible with the intermediate portion of the tubular access device, such ...

Abstract

A surgical stabilizer for use with a surgical site retractor has a base, a bendable arm, and a distal cuff adapted to resiliently hold a tube of an elongated port-access device. The cuff may have a body defining a partial enclosure within which is held a highly flexible gasket having a slit for resiliently receiving the tube. The surgical site retractor may have a collapsible ring and a flexible outer portion attached thereto, the ring being sized to pass through an intercostal incision and expand therein under adjacent ribs to prevent removal, and the flexible outer portion extending out of the incision and drawing over the stabilizer base to mutually secure the retractor and base. The port-access tube may be for a heart valve delivery system using an elongated port-access device for transapically delivering a prosthetic heart valve to the aortic valve annulus.; A method involves partly installing the surgical site retractor, anchoring the base of the stabilizer with the flexible outer portion, deploying the port-access tube from outside the body through the incision and through a puncture in the heart wall, and resiliently capturing a tube of the port-access within the partial enclosure of the stabilizer cuff. A second bendable arm on the base having a clip may be used to hold still a proximal end of the port-access device.

Description

[0001] related application [0002] This application claims priority under 35 USC § 119(e) to US Provisional Application No. 61 / 229,675, filed July 29, 2009. field of invention [0003] The present invention relates, more particularly, to methods and systems for stabilizing tubular surgical port-access devices during cardiac surgery. Background of the invention [0004] Heart valve disease continues to be an important cause of morbidity and mortality from many diseases, including rheumatic fever and birth defects. Valvular heart disease is a cause of nearly 20,000 deaths and a contributing factor to approximately 42,000 deaths each year in the United States at the most recent count. Currently, the mainstay of treatment for aortic valve disease is valve replacement. Worldwide, approximately 300,000 heart valve replacement surgeries are performed each year. [0005] Coronary artery disease also remains a major cause of morbidity and mortality and manifests itself in variou...
