Abstract
Techniques for modeling therapy fields for therapy delivered by medical devices are described. Each therapy field model is based on a set of therapy parameters and represents where therapy will propagate from the therapy system delivering therapy according to the set of therapy parameters. Therapy field models may be useful in guiding the modification of therapy parameters. As one example, a processor compares an algorithmic model of a therapy field to a reference therapy field and adjusts at least one therapy parameter based on the comparison. As another example, a processor adjusts at least one therapy parameter to increase an operating efficiency of the therapy system while substantially maintaining the modeled therapy field.
Claims31
A method comprising:
- detecting, by a processor, a patient event of a patient while a medical device is delivering therapy to the patient according to a therapy program determined based on a first reference therapy field applicable to a patient condition of the patient;
- automatically determining, by the processor and based on the detected patient event, that the first reference therapy field is no longer applicable to the patient condition;
- determining, by the processor, a second reference therapy field, based on determining that the first reference therapy field is no longer applicable to the patient condition, wherein the second reference therapy field is different from the first reference therapy field and represents where therapy will propagate in tissue of the patient from a therapy system;
- and
- adjusting, by the processor, a value of at least one therapy parameter of the therapy program based on the second reference therapy field.
A system comprising:
- a medical device configured to deliver therapy to a patient according to a therapy program, wherein the therapy program is determined based on a first reference therapy field applicable to a patient condition of the patient;
- and
- a processor configured to:
- detect a patient event of the patient while the medical device is delivering the therapy to the patient according to the therapy program,
- automatically determine, based on the detected patient event, that the first reference therapy field is no longer applicable to the patient condition,
- determine a second reference therapy field, based on determining that the first reference therapy field is no longer applicable to the patient condition, wherein the second reference therapy field is different from the first reference therapy field and represents where therapy will propagate in tissue of the patient from a therapy system;
- and
- adjust a value of at least one therapy parameter of the therapy program based on the second reference therapy field.
A system comprising:
- means for detecting a patient event of a patient while a medical device is delivering therapy to the patient according to a therapy program determined based on a first reference therapy field applicable to a patient condition of the patient;
- means for automatically determining, based on the detected patient event, that the first reference therapy field is no longer applicable to the patient condition;
- means for determining a second reference therapy field, based on determining that the first reference therapy field is no longer applicable to the patient condition, wherein the second reference therapy field is different from the first reference therapy field and represents where therapy will propagate in tissue of the patient from a therapy system;
- and
- means for adjusting a value of at least one therapy parameter of the therapy program based on the second reference therapy field.
