US Patent:

57499101, May 12, 1998

Filed:

Jun 7, 1995

Appl. No.:

8/486759

Inventors:

Dennis A. Brumwell - Bloomington MN
Joseph S. Perttu - Chanhassen MN
Mark W. Kroll - Minnetonka MN
Randall S. Nelson - Pine Springs MN

Assignee:

Angeion Corporation - Plymouth MN

International Classification:

A61N 1375

US Classification:

607 36

Abstract:

An implantable cardioverter defibrillator capable of subcutaneous positioning within a patient delivers at least one electrical cardioversion/defibrillation countershocks to the heart of the patient. The implantable cardioverter defibrillator includes a housing, circuitry positioned within the housing to control delivery of the countershocks, and an energy source coupled with the circuitry to provide electrical energy to a capacitor in the circuitry that stores the electrical energy for delivery of the countershocks. Because the circuitry is susceptible to undesirable electromagnetic coupling effects of origin external to the circuitry, particularly the capacitive coupling effects between the circuitry and the housing of the device when at least a portion of the housing is utilized as an electrode, the implantable cardioverter defibrillator also includes a conductive shield, disposed between the housing and the circuitry, to shield the circuitry against such undesired coupling effects.

International Classification:

H04M 350
H04M 706
H04M 1100

US Classification:

379 67

Abstract:

This invention relates to arrangements for providing a new spontaneous voice message service to any telephone customer at any telephone station when that customer encounters any destination that is busy or that does not answer. When a customer having a dual tone multifrequency (DTMF) station calls any destination that is busy or does not answer, the customer is invited, via an announcement identifying the new service, to record the caller's voice message. The announcement accompanies the returned busy tone or audible ring signal. The customer keys *867(=*VMS) and is then connected to a Voice Message Operations Center (VMOC) which prompts the customer to record the message. Advantageously, customers need not redial a VMOC number, their own number, and a destination number to reach a VMOC for storing the video message; the added convenience of this arrangement should stimulate substantial additional use of voice message service. The announcement, at very low cost, makes the customers aware of the service at the time they are most likely to use the service.

International Classification:

A61N 139

US Classification:

607 5

Abstract:

An electrode system for an implantable cardioverter defibrillator. The electrode system includes a conductive structure which is physically and electrically connected to the housing or can of the implantable cardioverter defibrillator and is used as an electrode in combination with an existing implantable cardioverter defibrillator electrode or electrodes. The electrode system provides a therapeutically significant increase in the effective surface area of the implantable cardioverter defibrillator's electrodes without requiring an additional header connection, feedthru, or cable.

International Classification:

A61N 1375
A61N 139

US Classification:

607116

Abstract:

The present invention is a one piece, disposable pulse generator emulator for emulating a subcutaneous implantable cardioverter defibrillator (ICD) having an active housing electrode. The emulator of the present invention is for use with an external test system to screen a patient for candidacy for an ICD by determining the patient's minimum defibrillation threshold voltage. The one piece, disposable emulator has a housing that has substantially the same conductive geometry as the desired implantable pulse generator.

Assignee:

Stone Products, Inc. - Prior Lake MN

International Classification:

A62B 3500

US Classification:

119857

Abstract:

A device for providing a gripping aid for the tandem passenger of a vehicle is described. The device includes a harness worn by the operator of the vehicle. The harness is secured around the upper region of the operator's torso, and the gripping handles are attached to the harness such that the passenger can be positioned closer to the operator while comfortably gripping the handles. An adjustable, quick release clasp allows the operator to quickly put on, remove, and adjust the harness.

Abstract:

An electronic module housing having a rounded stylized dog-bone-type shape and an equatorial partial light bar. The shape provides a view of parts of the light bar from many locations. The controller circuitry can detect a malfunction among one or more of a plurality of current-drawing components by detecting that the total cumulative current drawing by all the components falls outside a predetermined nominal range.
