US Patent:

49276433, May 22, 1990

Filed:

Nov 23, 1988

Appl. No.:

7/275418

Inventors:

Vincent T. D'Orazio - Racine WI
Robert B. O'Brien - Racine WI

International Classification:

A01K 8500

US Classification:

426 1

Abstract:

A water-soluble polymeric fishing lure coating having a odoriferous fish-attractant material dispersed therein. A composition for application onto fishing lures to provide olfactory stimulation of fish includes a volatile solvent, a polymeric material dissolved in the solvent and capable of forming a water-soluble coating, and an fish-attractant material dispersed in the solution. A method for imparting an olfactory stimulus to a fishing lure includes applying such composition onto the lure, preferably by spraying, dipping or brushing, and then exposing the lure to air for volatilization of the solvent.

Assignee:

Wisconsin Alumni Research Foundation - Madison WI

International Classification:

A61B 1756

US Classification:

606 90

Abstract:

An apparatus is employed to determine hip joint laxity in canines. The apparatus, which is adjustable for the size of the canine, is placed between the thighs of a canine patient in ventral recumbency, the pelvic limbs are manipulated to compress or distract the coxofemoral joint and the compression or distraction is imaging by non-radiographic means.

Appl. No.:

9/469671

Inventors:

Robert T. O'Brien - Madison WI
Rudolf Dueland - Black Earth WI

Assignee:

Wisconsin Alumni Research Foundation - Madison WI

International Classification:

A61B 500

US Classification:

600407

Abstract:

A method for distracting a coxofemoral joint of a patient having two hind legs includes the steps of placing the patient in ventral recumbency, positioning a distractor between the upper thighs so that the distractor acts as a fulcrum for lateral displacement of the coxofemoral joint, and applying inward pressure to the stifle regions to distract the coxofemoral joint. Related methods are also disclosed for imaging a distracted coxofemoral joint and for evaluating the likelihood of developing laxity of a coxofemoral joint in a patient. The imaging can be non-radiographic. A distractor apparatus, suitable for use in the methods, is also described.
