First Claim
1. A method for performing trial screening with a medical device system, the medical device system providing treatment to a patient with a nervous system disorder producing one or more neurological events, the method comprising:
- (a) receiving a first input into at least one processor relating to a location of treatment therapy delivery;
(b) receiving a second input into the at least one processor about a set of therapy parameters that is associated with a treatment therapy;
(c) administering a treatment therapy by the at least one processor in accordance with the first and second inputs; and
(d) receiving a first indication at the at least one processor whether the treatment therapy is within a range of safety and a second indication at the at least one processor whether to utilize the first and second inputs, wherein the second indication is determined by evaluating a criterion, wherein the criterion is selected from a group consisting of a detection frequency of the one or more neurological events produced by the nervous system disorder, a duration of the one or more neurological events, an intensity of the one or more neurological events, and an electrographic spread of the one or more neurological events.

Abstract
Apparatus and method support a neurological event screening for a medical device. The medical device assists a user in determining a configuration of the medical device for delivering an effective treatment for a nervous system disorder. The medical device detects a neurological event, such as a seizure, and reports a neurological event focus location and a neurological event spread to the user. The user may use the information to provide a configuration of a therapeutic delivery unit and associated therapy parameters. Therapeutic treatment is delivered to the patient, and the medical device is provided an indication of the patient'"'"'s acceptance to the treatment. The user may modify the configuration and therapy parameters in order to achieve efficacy and acceptance. Depending upon the patient'"'"'s acceptance, therapy is applied in either an open loop mode or a closed loop mode. The medical device determines whether the treatment is successful in accordance with a criterion.

11. A method for performing neurological event screening with a medical device system, the medical device system providing treatment to a patient with a nervous system disorder producing one or more neurological events, the method comprising:
-
(a) detecting an occurrence of a neurological event produced by the nervous system disorder by using a set of monitoring elements that obtains a set of neurological signals indicative of the neurological event; (b) automatically identifying a neurological event focus location that is associated with the neurological event using at least one processor; (c) reporting information about the neurological event focus location to an output device; (d) identifying a neurological event spread that is associated with the neurological event using the at least one processor; (e) reporting the neurological event spread to the output device; (f) receiving a first input at the at least one processor about a configuration of a treatment delivery unit that is associated with the neurological event screening; (g) receiving a second input at the at least one processor about a set of therapy parameters that is associated with a treatment therapy; (h) administering the treatment therapy by the at least one processor in accordance with the first and second inputs; (i) receiving a first indication at the at least one processor whether the treatment therapy is within a range of safety and a second indication at the at least one processor whether to utilize the first and second inputs, wherein the second indication is determined by evaluating a criterion characterizing the neurological event; and (j) if the first indication indicates that the treatment therapy is within a range of safety and if the second indication indicates that the first and second inputs are to be used, administering the treatment therapy by the at least one processor at a future point in time. - View Dependent Claims (12, 13)

14. A method for performing trial screening with a medical device system, the medical device system providing treatment to a patient with a nervous system disorder producing one or more detection clusters, the method comprising the steps of:
-
(a) receiving a first input into at least one processor relating to a location of treatment therapy delivery; (b) receiving a second input into at least one processor about a set of therapy parameters that is associated with a treatment therapy; (c) administering the treatment therapy by the at least one processor in accordance with the first and second inputs, wherein the administering of the treatment comprises; (i) applying the treatment therapy every nth detection cluster; (d) receiving a first indication at the at least one processor whether the treatment therapy is within a range of safety and a second indication at the at least one processor whether to utilize the first and second inputs, wherein the second indication is in accordance with an evaluation of a criterion, the evaluation comprising; (i) obtaining treatment data by the at least one processor for a first detection cluster produced by the nervous system disorder, wherein the treatment therapy is applied; (ii) obtaining comparison data by the at least one processor for a second detection cluster produced by the nervous system disorder, wherein the treatment therapy is not applied, and wherein the comparison data correspond to the treatment data; (iii) deleting a portion of the comparison data by the at least one processor corresponding to a blanking interval of the treatment therapy; and (iv) calculating a difference by the at least one processor between the treatment data and the comparison data in order to determine the efficacy of the treatment therapy; and (e) if the first indication indicates that the treatment therapy is within the range of safety and if the second indication indicates that the first and second inputs are to be used, administering the treatment therapy at a future point in time. - View Dependent Claims (15)
