Abstract
A medical system including an implantable medical device having at least first and second bores, the first bore configured to receive a first lead, the first lead configured to deliver a first therapy, the second bore configured to receive a second lead, the second lead configured to deliver a second therapy, and a lead reversal detection circuit connected to the at least first and second bores, for detecting insertion of the first or second leads into the wrong bore.
Claims20
A medical system, comprising:
- an implantable medical device having a first bore and a second bore, the first bore configured to receive a first lead, the first lead configured to perform a first function, the second bore configured to receive a second lead, the second lead configured to perform a second function;
- and
- a lead reversal detection circuit connected to at least one of the first bore and the second bore, the lead reversal detection circuit configured to detect one or both of insertion of the first lead into the second bore and insertion of the second lead into the first bore, and to generate an indication of lead reversal based on detection of one or both of insertion of the first lead into the second bore and insertion of the second lead into the first bore.
A method of detecting lead reversal in an implantable medical device having a first bore and a second bore, the method comprising:
- performing a first measurement of a parameter, the first measurement performed through the first bore;
- comparing the first measurement to a first threshold or range, the first threshold or range based on a first level of the parameter expected when a first lead is inserted into the first bore, the comparison performed by a lead reversal detection circuit;
- and
- generating an indication of lead reversal based on the comparison of the first measurement to the first threshold or range indicating that a second lead is inserted into the first bore, the indication generated by the lead reversal detection circuit.
A medical system comprising:
- an implantable medical device having a first bore and a second bore, the first bore configured to receive a first lead, the implantable medical device configured to deliver a LV therapy through the first bore and deliver a HV therapy through the second bore, the first lead having a first plurality of electrodes configured to deliver the LV therapy, the second lead having a second plurality of electrodes configured to deliver the HV therapy;
- and
- a lead reversal detection circuit connected to the first bore and the second bore, the lead reversal detection circuit configured to detect a condition of insertion of the first lead into the second bore and insertion of the second lead into the first bore, and to generate an indication of lead reversal based on detection of the condition.
