Today we fea­ture an impor­tant Medtron­ic patent. (As men­tioned, we are dis­cussing foun­da­tion­al Per­va­sive Neu­rotech patents, from old­er to new­er by issue date)

U.S. Patent No. 8,187,181: Scor­ing of sensed neu­ro­log­i­cal sig­nals for use with a med­ical device sys­tem

  • Assignee(s): Medtron­ic, Inc.
  • Inventor(s): Ivan Oso­rio, Mark G. Frei, Nina M. Graves, Jonathon E. Gif­takis
  • Tech­nol­o­gy Cat­e­go­ry: Neu­ro-mon­i­tor­ing
  • Issue Date: May 29, 2012

SharpBrains’ Take:

While some events caused by neu­ro­log­i­cal dis­or­ders are read­i­ly appar­ent, oth­er unde­sir­able neu­ro­log­i­cal activ­i­ty may still occur but be less vis­i­ble with the patient not exhibit­ing symp­toms. Such activ­i­ty may go unde­tect­ed and result in dis­or­ders wors­en­ing due to lack of treat­ment. The ‘181 patent describes tech­niques for detect­ing, rank­ing and pre­sent­ing neu­ro­log­i­cal events of vary­ing sever­i­ty, in some cas­es enabling more sub­tle afflic­tions to be dis­cerned. A spec­i­fi­ca­tion span­ning 33 illus­tra­tion sheets and 22 pages of writ­ten mate­r­i­al dis­clos­es var­i­ous aspects of detect­ing fea­tures of such events includ­ing iden­ti­fy­ing the sever­i­ty of activ­i­ty based on the inten­si­ty, dura­tion or spread­ing of neur­al clus­ter­ing activ­i­ty (see illus­tra­tive image above). The impor­tance of the addressed prob­lem space, inde­pen­dent claim cov­er­age of the inven­tive con­cept, exten­sive spec­i­fi­ca­tion and 80+ for­ward cita­tions are among that con­tribute to mak­ing the ‘181 patent as a key non-inva­sive neu­rote­chol­o­gy patent.


A med­ical device sys­tem capa­ble of scor­ing a sever­i­ty of sensed neu­ro­log­i­cal sig­nals relat­ing to a ner­vous sys­tem dis­or­der. The sys­tem com­pris­es a mon­i­tor­ing ele­ment that receives a neu­ro­log­i­cal sig­nal hav­ing at least one event to be scored. The med­ical device sys­tem iden­ti­fies one or more fea­tures of the neu­ro­log­i­cal sig­nal to use in scor­ing and com­putes a score of rel­a­tive sever­i­ty of the event using the iden­ti­fied fea­ture. Once two or more events have been scored, the events may be ranked by sever­i­ty rel­a­tive to each oth­er.

Illus­tra­tive Claim 12. A com­put­er-imple­ment­ed method for deter­min­ing the sever­i­ty of a detec­tion clus­ter com­pris­ing:

  1. deter­min­ing using a proces­sor that one or more sensed neu­ro­log­i­cal sig­nals rep­re­sent a plu­ral­i­ty of detec­tion clus­ters;
  2. iden­ti­fy­ing using a proces­sor at least one fea­ture of each of the detec­tion clus­ters;
  3. com­put­ing using a proces­sor a rel­a­tive sever­i­ty score for each of the detec­tion clus­ters using the iden­ti­fied at least one fea­ture; and
  4. rank­ing using a proces­sor the plu­ral­i­ty of detec­tion clus­ters by sever­i­ty using the rel­a­tive sever­i­ty scores.
