    Abstract: A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

  • Patent number: 6913600
    Abstract: Devices and methods are provided for temporarily inducing cardioplegic arrest in the heart of a patient and for establishing cardiopulmonary bypass in order to facilitate surgical procedures on the heart and its related blood vessels. Specifically, a catheter based system is provided for isolating the heart and coronary blood vessels of a patient from the remainder of the arterial system and for infusing a cardioplegic agent into the patient's coronary arteries to induce cardioplegic arrest in the heart. The system includes an endoaortic partitioning catheter having an expandable balloon at its distal end which is expanded within the ascending aorta to occlude the aortic lumen between the coronary ostia and the brachiocephalic artery. Means for centering the catheter tip within the ascending aorta include specially curved shaft configurations, eccentric or shaped occlusion balloons and a steerable catheter tip, which may be used separately or in combination.

  • Patent number: 6712782
    Abstract: A brachytherapy apparatus is composed of a tubular needle with forwardly protruding cutting edges at its tip, a holder supporting the needle and a driver for electromechanically causing the needle to undergo a continuous or oscillatory rotary motion around its axis and/or a reciprocating linear motion in the longitudinal direction such that its front opening at its tip can reliably reach a specified position inside a patient's tissue without being deflected or bowing when it encounters an obstruction such as a calcification or a small bone. Such motions may be provided by a piezoelectric hammer and a piezoelectric tamper. After the needle is thus correctly positioned, a brachytherapy device such as a radioactive seed or a reflector may be pushed through and out of the needle by means of a pusher as the needle is retracted to leave a track inside the tissue. A quickly hardening liquid may be thereafter injected through the needle to immobilize the deposited brachytherapy device.

  • Patent number: 6629987
    Abstract: The present invention provides a catheter positioning system which serves to control and stabilize a distal end of a catheter at a treatment site within a patient so that a medical procedure can be performed with accuracy. Generally, the positioning system operates by providing a deformable mechanical members at the distal end of the catheter which can be operated from the proximal end of the catheter to extend radially outward to engage surrounding tissue adjacent to treatment site. In one embodiment of the invention a flexible superstructure comprising the plurality of flexible veins extending longitudinally along the distal end of the catheter can be deformed to bow radially outward to engage surrounding tissue. The distal tip of the catheter joined to one of the veins was correspondingly displaced or rotated angularly as the veins bow outward.
