International Classification:

A63B 6900

US Classification:

473422, 473446, 36 1, 36132

Abstract:

A training shoe for soccer includes a pressure-responsive sensor mounted with respect to a soccer shoe at a selected location, for example at the instep or along the laces at the top of the shoe. When a soccer ball is kicked at the selected location, the sensor provides an electrical signal to a microprocessor, causing selection logic in the microprocessor to choose one of several control words. The selected control word is provided to a voice playback circuit to select one of several digital data sets, each set corresponding to a different sound. The playback circuit provides an analog electrical control signal to a speaker, thereby generating a selected sound corresponding to the selected digital data set. System components can be mounted permanently to a shoe, or to a cover or strap arrangement releasably mounted to the shoe.

5/949088

Inventors:

Richard L. Little - Minneapolis MN

Assignee:

Daig Corporation - Minnetonka MN

International Classification:

A61N 104

US Classification:

128786

Abstract:

Temporary pacemaker lead apparatus that includes a bifurcated lead assembly having a first and a second electric conductor pin connectable to terminals of an external pulse generator, a ring electrode more closely adjacent to the pins than the tip electrode, a first electric conductor having a first end electrically connected to the first pin, an intermediate portion extending through a tubular member and a second end electrically connected to the tip electrode, a second electric conductor connected to the second pin, an intermediate portion extended through the above mentioned tubular member and a second end connected to the ring electrode, a junction member having the first and second conductor intermediate portions extended therethrough, the junction member having means which connects to the head portion of a lead introducer cannula head portion for storing the cannula after the cannula has been used in extending the electrode end portion of the lead assembly into a body vessel, for example a vein. A needle is extended through the cannula for initially puncturing the body vessel.

Appl. No.:

5/945113

Inventors:

Richard L. Little - Minneapolis MN

Assignee:

Daig Corporation - Minnetonka MN

International Classification:

H01R 1132

US Classification:

339183

Abstract:

A pacemaker bipolar lead assembly, for being electrically connected to a pulse generator to transmit electrical pulses into a heart, that includes a pair of wire conductor spring coils electrically connected to conductor pins, the first coil being electrically connected to a tip electrode and the second coil being electrically connected to a ring electrode. An internal ring having an outwardly facing groove is press fitted within the ring electrode with the second coil extending through the groove to retain the second coil in electrical conducting relationship with the ring electrode. Electrical insulation is provided on the coils and the conductor pins except for one end portions of the pins, the part of the second coil that is in electrical contact with the ring electrode and the juncture of the first coil with the tip electrode. An insulated portion of the first coil extends through the internal ring.

Appl. No.:

7/333253

Inventors:

Richard L. Little - Minneapolis MN

Assignee:

MedAmicus, Inc. - Minneapolis MN

International Classification:

A61M 2500

US Classification:

604280

Abstract:

This invention relates to an introducer slitter for slitting an introducer tube portion having, for example, a catheter extending therethrough and into a body vessel while the introducer tube is moved rearwardly relative to the catheter to facilitate separating the introducer from the catheter without having to slide the introducer tube portion over the proximal end of the catheter. The slitter includes an arcuate section having an inner peripheral wall that extends arcuately through an angle of at least about 180. degree. and is adapted to abut against the catheter, and a nose portion that extends between the catheter and introducer tube portions as the introducer is moved axially rearwardly relative to the catheter, a handle section extending radially outwardly of the arcuate section and a radially extending cutting edge for engaging the introducer tube portion for slitting the introducer tube portion as the introducer is pulled rearwardly relative to the slitter.

International Classification:

A61M 2500
G01L 708

US Classification:

128748

Abstract:

A physiological pressure transducer assembly mounted on a transvenously-insertable guide wire is disclosed. The multiple coils of the guide wire define an elongated tubular passage within which fiber optic leads are contained for the transmission of light signals to a pressure transducer. A window or aperture is cut along a restricted portion of the length of the guide wire coil to provide a pressure-sensing aperture over which an elastic, pressure-sensitive membrane is positioned. The coils of the guide wire adjacent to the sensing aperture are joined together for increased rigidity along the length of the pressure transducer assembly, as by soldering or brazing. A separate, cylindrical housing, preferably of molded plastic, is wholly contained within the reinforced length of the guide wire. The proximal end portions of fiber optic sending and receiving leads or paths are received and contained within the housing in a predetermined arrangement and geometry defining a light-transmitting gap. Light transmission across the gap is controllably attenuated by deflection of the pressure-responsive membrane in response to pressure changes within a person's body, and the attenuated light signals are transmitted to an external control unit as indicative of pressure changes.

US Classification:

128748

Abstract:

A fiber optic transducer utilizing a flexible membrane to transduce pressure by interrupting light transmission between fiber optic paths in a catheter or guide wire carrier by misaligning the paths or by interposing a blocking opaque shutter between the paths. Calibration data may be carried by the individual transducer in machine readable form.
