Publication number: 20120271334Abstract: A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length.Type: ApplicationFiled: July 2, 2012Publication date: October 25, 2012Inventors: Benjamin Pless, Scott C. Anderson, Jonathan L. Podmore, Matthias Vaska, John E. Crowe, Roxanne L. Richman, Timothy Ciciarelli, David A. Gallup, Jack E. Ulstad, JR.

Publication number: 20040260278Abstract: The invention provides apparatus and methods for ablating tissue and is particularly useful for creating lesions in the heart wall for the treatment of atrial fibrillation. The apparatus has a suction well which is adhered to the tissue to be ablated. The ablating element is surrounded by the suction well. A fluid is delivered to the ablating element to conduct RF energy to the tissue and/or to cool the tissue. The device is preferably formed with a number of cells with each cell having a suction well and at least one ablating element. The device also preferably has a locking mechanism for locking one part of the device to another part of the device to form a closed loop for ablating around structures such as the pulmonary veins.Type: ApplicationFiled: April 12, 2004Publication date: December 23, 2004Inventors: Scott C.

Patent number: 5474546Abstract: A dripless cannula system usable with a syringe or other fluid container in a fluid sampling procedure and operable to minimize retention of residual fluids at a sampling site following the sampling procedure. In the preferred embodiment, a vacuum chamber operatively connected to a blunt cannula of the dripless cannula system is operative upon withdrawal of the cannula from the sampling site to draw residual fluids at the site into the vacuum chamber for subsequent disposal. The dripless cannula system of the present invention is a simple, effective apparatus for minimizing the presence of residual fluids at a sampling site following a sampling procedure.Type: GrantFiled: May 9, 1994Date of Patent: December 12, 1995Assignee: Abbott LaboratoriesInventors: William M.
