Filed:

Aug 18, 2006

Appl. No.:

11/465612

Inventors:

Jason D. Toman - Swissvale PA, US
Douglas A. Staunton - Kalamazoo MI, US

Assignee:

Stryker Corporation - Kalamazoo MI

International Classification:

A61M 5/00
A61M 5/20

US Classification:

604247, 604173

Abstract:

An infusion assembly for delivering therapeutic fluid to plural body sites is provided. The assembly includes a positive displacement pump that discharges the therapeutic fluid. The assembly also includes a flow regulator valve including a valve housing that defines a pressure chamber, an inlet bore that opens into the pressure chamber, and first and second outlet passageways. The first and second outlet passageways extend, respectively, from separate first and second outlet openings to a first catheter and a second catheter through which the therapeutic fluid is directed to the body sites. A controller cyclically regulates the operation of the pump so that, in a first phase of each cycle, the pump is actuated so as to cause a fluid pulse to be presented through the inlet bore of the valve housing to the diaphragm and in a second phase of each cycle, the pump is not actuated.

International Classification:

A61B 18/14

US Classification:

606 41, 606 48

Abstract:

An electrosurgical system preferably used for denervation procedures of nerve tissue has a control unit and a pluggable electrode assembly. The electrode assembly has a preferably disposable cannula and a preservable supply electrode assembly. The cannula has a tubular body that projects axially from a preferably pointed distal end for piercing tissue to a proximal end engaged to a first coupling assembly of the cannula. The body carries a first contact exposed directly to the nerve tissue and connected electrically to a terminal of the first coupling assembly. The supply electrode assembly has a second coupling assembly and a supply electrode that projects axially and removably into a through-bore of the body when the tool is in an operating state. The second coupling assembly carries a terminal that abuts the first coupling assembly when the coupling assemblies are mated. Preferably the supply electrode carries a temperature sensor for temperature measurement of the targeted tissue and processing by the control unit.

International Classification:

A61N 1/05

US Classification:

607116

Abstract:

An electrode array assembly with a frame that is foldable or bendable on which electrodes are disposed. The frame includes laterally spaced apart bridges. Tabs extend laterally outwardly from the bridges Electrodes are disposed on the tabs. Beams, also part of the frame, extend between the laterally adjacent bridges. The frame can be folded around the beams so as to cause the laterally spaced bridges to at least partially overlap. When the beams are so bent, the electrode carrying tabs extend beyond the bent beams.

Inventors:

Douglas Staunton - Kalamazoo MI, US
Eland Cramlet - Portage MI, US

International Classification:

A61B018/14

US Classification:

606041000

Abstract:

The invention provides an electrode assembly for a system for performing an electrosurgical procedure using electrical energy. The electrode assembly includes an electrode defining a blind aperture for receiving a thermocouple and formed from nitinol. The nitinol electrode is super-elastic, resistant to corrosion, and bio-compatible. In the exemplary embodiment of the invention, a thermocouple is disposed in the blind aperture.

International Classification:

A61N 132

US Classification:

607 72

Abstract:

A neuro-muscular electrical stimulation system provides a series of electrical pulses to instigate muscle twitch to aid in preventing the occurrence of deep vein thrombosis. The duration and duty cycle of the electrical pulses provided to a patient's muscle tissue is controlled to instigate muscle twitch without causing tetanic muscle contractions. The system preferably includes a single electrode that is placed upon each calve of a patient. The electrical stimulator device includes a unique housing and circuit board arrangement that facilitates easy assembly without requiring any soldering connections between the circuit board, a power source and electrical leads that are utilized to provide signals to the electrodes that are placed on the patient. The circuit board preferably is made from a slightly resilient plastic material that is flexed from a disconnected position into an electrically connected position upon assembly of the stimulator device.

Abstract:

Surgical systems and methods to interact with a limb of a patient held by a limb holder. An instrument is configured to apply a force externally to the limb held by the limb holder, One or more controllers measure an extent to which the limb moves relative to the limb holder in response to the force applied externally to the limb by the instrument. The one or more controllers generate, based on the measured extent, a notification relating to physical adjustment of one or both of the limb and the limb holder.
