A method of performing minimally invasive cardiac surgery includes the step of creating an access aperture into a patient's chest cavity, the access aperture being considerably smaller than a traditional cardiac surgery incision. A cannula is provided that has an oval portion with a longer major axis and a shorter minor axis and the cannula is inserted into the chest cavity through the access aperture.

Oval-shaped cardiac cannula

An obturator for a cannula includes an elongate member and a flexible disc. The cannula has proximal and distal ends and a lumen extending therebetween. The distal end of the cannula has a circular cross-section. The cannula also includes a first portion having a non-circular cross-section and at least one fluid aperture formed adjacent the distal end. The flexible disc of the obturator is coupled to a distal end of the elongate member, both of which are adapted to be telescopically received in the lumen of the cannula. The flexible disc is configured to restrict the flow of fluid, entering the at least one fluid aperture, through the lumen.

An intravascular device is provided. The device comprises a sealing member, the member including a mesh material and a gripping element operatively attached to the sealing member, the gripping element operatively adapted to allow a user to position the sealing member to seal a blood vessel. Methods of using the device are also provided.

An endoscopic stabilization device is provided. The device includes first and second support elements positioned opposite each other, a plurality of linkages, each linkage including a first end portion attached to the first support element and a second end portion attached to the second support element; and a cable operatively attached to the linkages at a first end to allow a user to pull a second end of the cable to move the first support element in a direction away from the second support element. Methods of using the device to stabilize and immobilize components in the body are also provided.

Endoscopic stabilization device and method of use

A cannula comprises a proximal end, a distal end, and a lumen extending between the proximal and distal ends, wherein at least a portion of the cannula body is non-circular in cross section, preferably oval. A cannula wherein a portion of the cannula body is oval in cross section is ideally suited in surgical procedures wherein the cannula extends through a percutaneous aperture. The oval portion of the cannula body utilizes the space of the percutaneous aperture efficiently, thereby minimizing the necessary size of the access aperture.

An apparatus and system for administering cardioplegic solution to a heart during open heart surgery. A source of solution is delivered to a control switch from a single tube source and the tube is divided at a 'Y' connector into two tubes, one for antegrade delivery and one for retrograde delivery. The control switch has a prime position with both divided tubes open. Movement from prime position to an operative position is irreversible. In the operative position, there is an 'off' position with both tubes closed, an antegrade position with the antegrade tube open and the retrograde tube closed, and a retrograde position with the retrograde tube open and the antegrade tube closed. Movement from one position to the other requires movement through the 'off' position so there can be no cross-flow from antegrade to retrograde. Pressure monitoring tubes are incorporated into the switch to be opened and closed with the respective tubes.

Antegrade-retrograde switch and occluder and system for using the same

A golf club holder is disclosed comprising an elongate tube of a resilient material having a first end open and adapted for receiving a golf club handle and shaft and a second end including a spring clip means formed from the tube for resiliently gripping a golf club handle and detachably retaining same within the tube. Preferably, the spring clip means comprises a portion of the tube adjacent the second end with a gradually reduced cross-sectional area created by one or more longitudinally extending folds in the tube. The spring clip means develops sufficient gripping force such that when a plurality of the elongate tubes are arranged in a parallel array, and secured in a golf bag, the clubs inserted in the tubes will not fall from the bag even when the bag is held upside down. Additionally, a rack is disposed above the tubes to prevent the heads of the clubs from interfering.
