Принадлежит: MedicineLodge Inc

A surgical rasping system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping head which may be low profile and offer a flat cutting/rasping surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the rasping system to provide ablation or coagulation of soft tissues.

Method and apparatus for increasing blood flow through an obstructed blood vessel

Номер: US20120041459A1
Автор: David Fiorella, Henry Woo
Принадлежит: CLEVELAND CLINIC FOUNDATION

A method of increasing blood flow through an obstructed blood vessel includes providing an expandable member substantially made of a mesh having a plurality of interstices. The expandable member is inserted into the blood vessel, positioned within the blood vessel with the proximal member end upstream of the distal member end and the member body located radially adjacent at least a portion of an obstruction, and expanded to bring at least a portion of the member body into contact with the obstruction. An outward radial force is exerted on the obstruction to dislodge at least one fragment from the obstruction and to enhance blood flow through the blood vessel past the obstruction. The at least one fragment is passed through at least one interstice of the member body in the radial direction, and is selectively retained within the expandable member.

Rotational atherectomy device with electric motor

Номер: US20130018399A1
Автор: Cassandra Ann Piippo Svendsen, Charles A. Plowe, Jody Lee Rivers, Michael John Eng, Scott M. Hanson, Walter John Dobrovolny
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.

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 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.

Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm. For example, such small holes can be produced using a mechanical apparatus that includes one or more abrading elements provided at the end of one or more rotating shafts, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes thus formed can be well-tolerated by the skin, and may exhibit shorter healing times and less swelling than conventional resurfacing procedures. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The method and apparatus can produce cosmetic improvements in the skin appearance by eliciting a healing response.
