US Patent:

20180177456, Jun 28, 2018
Filed:

Dec 27, 2016
Appl. No.:

14/956813
Inventors:

Elsa Swanson - Philadelphia PA, US
Forrest Miller - Philadelphia PA, US
Emily Cen - Littlel Neck NY, US
David Xing - Providence RI, US
International Classification:

A61B 5/00
G01N 33/96
A61B 5/07
A61B 5/145
A61B 5/1459
A61B 5/1495
A61F 2/38
Abstract:

This invention relates to diagnostic medical instruments and procedures, and more particularly to implantable devices and methods for monitoring physiological parameters. A device for providing in vivo diagnostics of infections in orthopedic implants having at least one signal processing device operatively coupled with sensors. The signal processing device is operable to receive the output signal from the sensors and transmit a signal corresponding with the output signal. The invention also relates to a method using the device of the invention for detecting infection associated with implants in a human or animal subject.

US Patent:

20170156665, Jun 8, 2017
Filed:

Dec 2, 2016
Appl. No.:

15/367447
Inventors:

- Philadelphia PA, US
Elsa Swanson - Philadelphia PA, US
Emily Cen - Little Neck NY, US
David Xing - Providence RI, US
International Classification:

A61B 5/00
Abstract:

To assist diagnosis of a post-operative condition related to an implanted medical device, such as an infection, inflammation, mechanical wear, and hemorrhaging, a monitoring device optically measures a concentration of a selected type of cells in a fluid surrounding the implanted medical device. The monitoring device comprises a light source and light sensor which are selected and calibrated, and placed in a relative spatial orientation with respect to each other, to detect light scattered by the selected type of cell in the fluid.
