Filed:

Jul 23, 2004

Appl. No.:

10/897592

Inventors:

Jeffrey E. Christensen - Pullman WA, US
Pamela J. Squires - Marshfield WI, US
Kurt D. Reed - Marshfield WI, US

Assignee:

Marshfield Clinic - Marshfield WI

International Classification:

C12Q 1/68
C12P 19/34
G06F 19/00

US Classification:

435 6, 435 912, 7001041

Abstract:

Disclosed is a method of detecting bacteria in a biological sample, especially a blood sample, without the need for extensive sub-culturing of the sample. Nucleic acid present within the sample is isolated and bacterial DNA specifically amplified using primers that uniquely prime the amplification of 16s rRNA-encoding nucleic acid. The amplicons are then digested with an endonuclease to yield a restriction fragment length profile for the biological sample. The restriction fragment length profile for the biological sample is then compare to a database of profiles made using cultures of known bacterial species. A match between the sample profile and the database identifies the bacteria present in the sample.

International Classification:

A61B 17/17
A61B 17/15
A61B 17/66

Abstract:

Resection guides include a body a plurality of alignment pin through-holes and a plurality of guide through-holes so that the pattern of guide through-holes is operable for receiving a drill for use in resecting the at least a portion of the anatomical structure of the patient. Sweeping reamers include a body having a plurality of alignment pin through-holes and an elongated opening, and a reamer extendable through the elongated opening of the body. Decoupled resection guides include a first body having a plurality of alignment pin through-holes and a second body having a plurality of fixation pin through-holes and at least one guide aperture operable for guiding a cutting tool for use in resecting a portion of the second anatomical structure of the patient. Methods employing the same are disclosed and operable in, for example, total ankle replacement.
