Abstract
Electrical energy delivery tissue site validation systems and methods can determine an indication of a tissue type at a tissue site. This information can be used to enable or inhibit electrical energy delivery to the tissue site. The tissue type at the tissue site can be determined such as by delivering a test electrical energy and sensing a responsive electrical energy. An electrical connectivity to the tissue site can also be determined, such as by using a sensed intrinsic electrical signal at the tissue site. Tissue type information may be communicated externally, such as to allow user confirmation or override of the determined indication of tissue type at the tissue site, such as by a physician, user, or other operator.
Claims21
(canceled)
A system comprising:
- an electrical energy delivery circuit configured to deliver neurostimulation energy;
- a signal sensing circuit configured to sense a physiologic characteristic of at least one tissue site;
- a validation module, coupled to the electrical energy delivery circuit and the signal sensing circuit, configured to determine an indication of a cardiac tissue type at the at least one tissue site using the sensed physiologic characteristic;
- and
- a control circuit configured to inhibit the electrical energy delivery circuit from delivering the neurostimulation energy at least in response to the indication of the cardiac tissue type.
A system comprising:
- an electrical energy delivery circuit configured to deliver defibrillation energy or a cardiac pacing energy;
- a signal sensing circuit configured to sense a physiologic characteristic of at least one tissue site;
- a validation module, coupled to the electrical energy delivery circuit and the signal sensing circuit, configured to determine an indication of a neural tissue type at the at least one tissue site using the sensed physiologic characteristic;
- and
- a control circuit configured to inhibit the electrical energy delivery circuit from delivering the defibrillation energy or the cardiac pacing energy at least in response to the indication of the neural tissue type.
A method comprising:
- sensing a physiologic characteristic at at least one tissue site;
- determining an indication of a first tissue type at the at least one tissue site using the sensed physiologic characteristic, the first tissue type including a cardiac tissue or a neural tissue;
- in response to determining the indication of the first tissue type as being a cardiac tissue, inhibiting delivery of neurostimulation energy to the at least one tissue site;
- and
- in response to determining the indication of the first tissue type as being a neural tissue, inhibiting delivery of defibrillation energy or cardiac pacing energy to the at least one tissue site.
