  • Patent number: 7276055
    Abstract: 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.
    Type: Grant
    Filed: April 3, 2003
    Date of Patent: October 2, 2007

  • Patent number: 6645194
    Abstract: 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.

  • Patent number: 6146371
    Abstract: 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.

  • Patent number: 4194547
    Abstract: 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.
