International Classification:

H01L 4108

US Classification:

310328, 31032318, 31032319

Abstract:

An ultrasonic resonator comprising a wire member with an elongated shaft having a proximal end and a distal end, the proximal end further including a filler material disposed within the proximal end; a crimp screw with an annular end and a threaded end, the annular end adapted to receive and fixedly secure the proximal end of the wire member, the annular end being crimped after the proximal end of the wire member is inserted within the annular end of the crimp screw; an ultrasonic transducer adapted to receive the threaded end of the crimp screw; and the ultrasonic transducer operatively connected to an ultrasonic generator.

International Classification:

A61B017/32

US Classification:

606169, 604 22

Abstract:

A percutaneous surgical instrument for de-bulking calculi or drilling bone includes an actuator for generating vibrations at ultrasonic frequencies and a horn coupled to said actuator for amplifying the actuator vibration. A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and over said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

A fixed probe is attached to said horn for engaging the calculi and introducing the ultrasonic frequencies thereto. A floating probe is disposed concentric to and under said fixed probe and slidable thereover. A free mass is disposed between the horn and the floating probe for oscillating therebetween, in response to actuator vibration, for causing low frequency impact with the calculi.

Appl. No.:

9/480640

Inventors:

William R. Bell - Erie PA

Thomas M. Peterson - Erie PA

Assignee:

Hill-Rom Services, Inc. - Batesville IN

International Classification:

F21V 2126

US Classification:

362371

Abstract:

An arm assembly for supporting a surgical lighthead of a surgical light apparatus. The arm assembly includes a first arm and a second arm pivotally coupled to the first arm about a main pivot axis. A rod extends within an interior region of the second arm. A link is coupled to the rod to the first arm for pivoting movement about a link pivot axis that is spaced apart from the main pivot axis. A spring extends within the interior region of the second arm. The spring exerts a force on the rod and the link to counterbalance the surgical lighthead. A space filler includes an outer cover coupled to the first arm and formed to include a first slot and an inner cover nested within the outer cover and formed to include a second slot.

Assignee:

Transon LLC - San Francisco CA

International Classification:

A61B 1722

US Classification:

601 2

Abstract:

A multiple transducer assembly and method for coupling ultrasonic energy to a body for thrombolysis of vascular thrombi is provided. The assembly includes a catalytic transducer apparatus including a plurality of transducers for transmitting ultrasound into a medical target transcutaneously. Each transducer includes a front mass having structure which optimizes the transmission of ultrasound into the body. The transducers may share a common front mass. A reservoir for containing a cooling conductive medium between the front mass and the body surface is provided, and is contained within the housing. In addition, the catalytic transducer includes an irrigation manifold, disposed through a center of the front mass, for directing the medium into the reservoir generally along a perimeter thereof. The front mass includes an apex for accumulating expelled gasses. A sloped surface of the front mass functions to direct expelled gasses toward the apex and through an outlet provided by the irrigation manifold.

Filed:

Appl. No.:

6/930815

Inventors:

Thomas F. Peterson - Pepper Pike OH

International Classification:

G01R 3102

US Classification:

324 72

Abstract:

A hermetically sealed, electrically insulative enclosure (A) is surrounded by a Faraday cage (B). At least one electrode (C) is disposed within the hermetically sealed enclosure. The volume of the enclosure is selectively altered such that an initial charge density in the neighborhood of electrod changes, which changes the electrode potential. The change causes a current to flow to or from the electrode which returns the electrode potential and the electrode surrounding space charge toward an equilibrium condition. In one embodiment, a current measuring circuit (D) is disposed between the electrode and the Faraday cage to derive a measure of the current flow therebetween. In another embodiment, a like electrode is disposed within another hermetically, sealed insulative enclosure which is shielded by the same or another Faraday cage. In the second embodiment, the measuring circuit measures the current flow between the two isolated electrodes.
