  • Publication number: 20100049192
    Abstract: Systems and methods for non-thermal ablation of tissue are provided. A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided. A catheter for use in such system is further provided. The catheter includes a tubular body having a proximal end, a distal end, and a tip positioned at the distal end. The tubular body is semi-flexible, bi-directionally torqueable, and chemically resistant. The tubular body includes a plurality of routing holes provided between the proximal end and the distal end for facilitating deployment of electrodes from the tubular body. The tubular body further comprises an inner sheath generally at an interior portion and an outer sheath generally at an exterior portion and being chemically resistant.

  • Publication number: 20100049188
    Abstract: Systems and methods for non-thermal ablation of tissue are provided. A non-implantable minimally invasive system for treatment of tissue in a body via direct current ablation is provided including a catheter, a plurality of electrodes for deployment through the catheter, a power source for applying power to the electrodes, and a fixation element for maintaining the catheter in a treatment position during treatment of the tissue. A minimally invasive method for treating tissue in a body via direct current ablation is provided including inserting a catheter into the body such that a portion of the catheter remains outside of the body, deploying a fixation element to fix the catheter in a treatment position, deploying a plurality of electrodes through the catheter, applying power to the plurality of electrodes, using the electrodes to apply a current to the tissue, and removing the catheter from the body.

  • Publication number: 20100016861
    Abstract: One embodiment of the present subject matter includes a system (700) which includes a device (701) including a first body (702) which is hermetically sealed, a first terminal (706) coupled to the first body, a second body (704) which is part of the device and which is hermetically sealed, a second terminal (708) coupled to the second body, a threaded fastener (712) coupling the first terminal and the second terminal and a torque wrench (716) matable to the threaded fastener, the torque wrench including a tightening clutch (604) and a loosening clutch (608), the tightening clutch adapted to slip at a first torque, the loosening clutch adapted to slip at a second torque other than the first torque. A method of storing an implantable device (701) is also subject mater.

  • Publication number: 20080071178
    Abstract: An anchor for an implantable medical device, for example, and implantable physiologic sensor, includes a proximal hub portion, an intermediate portion extending radially and distally from the hub portion, and a distal portion extending distally from the proximal portion and adapted to engage an inner surface of a target vessel for securing the implantable medical device therein. The anchor can assume a collapsed configuration for delivery through a catheter, and an expanded configuration for fixation within the vessel once deployed. The intermediate portion extends from the proximal portion at an oblique angle, allowing the anchor to be retracted and re-collapsed within the delivery catheter after initial deployment, if re-positioning or removal of the implantable medical device is necessary or desired.

  • Publication number: 20080063490
    Abstract: One embodiment of the present subject matter includes a system for fastening a male terminal with a driver. The embodiment includes a body defining an at least partially threaded recess which intersects with a female recess adapted to receive the male terminal. The embodiment additionally includes a fastener having an at least partially threaded body and a flanged head adapted to mate with the driver, the fastener disposed at least part of the way in the first recess, the flange having a diameter which is larger than a diameter of the at least partially threaded recess. The embodiment includes a flexible septum coupled to the body and covering the first recess, the flexible septum having an opening sized for passage of the driver.
