Energy based devices and methods for treatment of patent foramen ovale

Номер: US20120010608A1
Автор: Dan Francis, Hanson S. Gifford, Iii, Jose Alejandro, Kenneth Horne, Mark E. Deem, William Malecki
Принадлежит: Terumo Corp

Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device fuirther include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

Tissue ablation with irreversible electroporation

Номер: US20120071874A1
Автор: Boris Rubinsky, Rafael Davalos
Принадлежит: UNIVERSITY OF CALIFORNIA

A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.

Impedance mediated control of power delivery for electrosurgery

Номер: US20130116678A1
Автор: Miriam H. Taimisto, Roseanne Varner, Tim Koss
Принадлежит: Aesculap AG

A method of controlling electrosurgical power delivery is based on a comparison of sensed tissue impedance to various impedance threshold values. Energy is delivered to tissue in a sealing cycle as a series of pulses. A pulse has a profile with a preset energy starting value that increases at a ramping rate to a preset end value. Sensed impedance data are monitored throughout each pulse and compared to each of an impedance threshold value for RF setpoint, an impedance threshold value for cumulative time, and an impedance threshold value for energy cutback. Based on sensed impedance during a pulse, the profile of a subsequent pulse can be modified. In the event of a high impedance event that reflects low tissue presence, energy may be cutback. A sealing cycle is stopped when a cumulative amount of time with an impedance value over the impedance cumulative time threshold value reaches a limit.

Принадлежит: Echo Therapeutics Inc

Devices, systems, kits and methods for increasing the skin's permeability controlled by measured skin electrical parameter are described herein. They may be used for transdermal drug delivery and/or analyte extraction or measurement. The controlled abrasion device contains (i) a hand piece, (ii) an abrasive tip, (iii) a feedback control mechanism, (iv) two or more electrodes, and (v) an electrical motor. Preferably the feedback control mechanism is an internal feedback control mechanism. In this embodiment, the abrasive tip contains two electrodes, i.e. both the source electrode and the return electrode. In another embodiment, the feedback control mechanism is an external feedback control. In the preferred embodiment for external feedback control, the device contains a co-axial or concentric arrangement of the two electrodes. In this embodiment, the abrasive tip contains the source electrode and the return electrode is located at the proximal end of the hand piece. The abrasive tip can be made of any material with a surface that can abrade skin. The material can be conductive or non-conductive. The controlled abrasion device may be provided in a kit, where the kit contains the device, one or more abrasive tips, optionally with a wetting fluid. The method for increasing the skin's permeability requires applying the controlled abrasion device to a portion of the skin's surface for a short period of time. The desired level of skin impedance, and thus the resulting permeability of the treated site, can be set at a predetermined value. Alternatively, the level of skin impedance can be selected based on the desired level of skin integrity, the subject's sensation of discomfort, or the duration of the application. The device contains a control mechanism which uses an appropriate algorithm or signal processing on the conductivity information provided by the electrodes to determine when the desired level of skin permeability has been reached.
