Surgical apparatus

Номер: US20120010540A1
Автор: Shinya Masuda
Принадлежит: OLYMPUS MEDICAL SYSTEMS CORP

A surgical apparatus includes an output mode switching section configured to selectively switch an output mode of a power supply main body, that can output the energy to a probe and a jaw, in accordance with a moving state of a movable member. The output mode switching section is configured to switch the output mode such that a bipolar mode in which the probe and the jaw are driven as high-frequency electrodes is set when the jaw is in a closed state with respect to the probe and a single output mode in which the energy is output from only the probe is set when the jaw is in an open state with respect to the probe.

Endoscopic balloon tissue dissector and retractor

Номер: US20120016196A1
Автор: Parviz Kambin, Sheila P. Kambin
Принадлежит: Individual

In endoscopic surgery, a retractor having independently spreadable retractor blades mounted at the distal end of a tube is introduced percutaneously. A balloon dissector is passed through the tube and expanded. Following dissection by expansion of the balloon, the balloon is contracted, the tube is advanced, and the dissected tissue is spread by moving the blades apart from each other. The balloon dissector is withdrawn and another instrument is then introduced to carry out surgery on the anatomical structure exposed by the dissection and spreading steps.

A tunneling tool for creating a pathway for implanting a therapy delivery element in a living body. The tunneling tool includes a malleable elongated shaft having a distal end. A sheath having a lumen is slidably positioned over a portion of the shaft. A primary handle secured to proximal end of the shaft permits a user to advance and manipulate the shaft and the sheath in the living body. A secondary handle with an opening is slidably positioned on the shaft between the primary handle and the sheath. The opening has a diameter less than an outside diameter of a proximal end of the sheath. A locking mechanism releasably engages the secondary handle to the primary handle. The sheath is retained in a desired location within the living body by securing the secondary handle relative to the living body as the primary handle is used to remove the shaft from the sheath.

Image guided high intensity focused ultrasound treatment of nerves

Номер: US20120316426A1
Автор: James W. Little, Jessica L. Foley, Shahram Vaezy
Принадлежит: UNIVERSITY OF WASHINGTON

A method for using high intensity focused ultrasound (HIFU) to treat neurological structures to achieve a desired therapeutic effect. Depending on the dosage of HIFU applied, it can have a reversible or irreversible effect on neural structures. For example, a relatively high dose of HIFU can be used to permanently block nerve function, to provide a non-invasive alternative to severing a nerve to treat severe spasticity. Relatively lower doses of HIFU can be used to reversibly block nerve function, to alleviate pain, to achieve an anesthetic effect, or to achieve a cosmetic effect. Where sensory nerves are not necessary for voluntary function, but are involved in pain associated with tumors or bone cancer, HIFU can be used to non-invasively destroy such sensory nerves to alleviate pain without drugs. Preferably, ultrasound imaging synchronized to the HIFU therapy is used to provide real-time ultrasound image guided HIFU therapy of neural structures.

Принадлежит: Cardiovascular Systems Inc

An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel. The freely-spinning motor allows the large angular momentum of the system to dissipate rapidly and safely, without excessive torque to the drive shaft.

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. Once the desired ...
