Abstract
Systems, methods, and devices to facilitate insertion of certain leads with electrode(s) into patients are described. Leads can be implanted to work in conjunction with a cardiac pacemaker or cardiac defibrillator. A lead for cardiac therapy may be inserted into an intercostal space associated with the cardiac notch of a patient. Devices for delivery may include, for example, a delivery system coupled with an electrical lead and having a handle, a component advancer and insertion tips. The handle is configured to be actuated by an operator and the component advancer is configured to advance an electrical lead into the patient. The insertion tips can be configured to close around the electrical lead within the component advancer, to push through biological tissue, and to open to enable the lead to advance into the patient. The electrical lead can also be maintained in a particular orientation during the advancement into the patient.
Claims (10)
1. An electrical lead for implantation in a patient, the lead comprising:
a distal portion comprising one or more electrodes, the one or more electrodes configured to generate therapeutic energy for biological tissue of the patient; and
a proximal portion coupled to the distal portion, the proximal portion configured to engage a controller when the lead is implanted in the patient, the controller configured to cause the electrode to generate the therapeutic energy,
wherein the distal portion includes a distal end and the distal end includes a flexible portion comprising one or more cutouts formed in one or more surfaces that are adapted to increase the flexibility of the distal end so as to allow the distal end to change course when encountering sufficient resistance traveling through the biological tissue of the patient,
wherein the distal end is at least partially paddle-shaped, having a planar surface that includes at least one of the one or more electrodes and another planar surface opposite the planar surface, the one or more cutouts including a first cutout formed in a first planar side of the distal end and a second cutout formed in a second planar side opposite the first planar side.
2. The lead of claim 1 , wherein the flexible portion comprises a material that flexes more easily relative to a material of another area of the distal portion.
3. The lead of claim 1 , the one or more cutouts comprising one or more areas having a reduced cross section compared to other areas of the distal portion.
4. The lead of claim 1 , wherein the flexible portion is configured to cause the distal end to be biased to change course in a particular direction.
5. The lead of claim 1 , wherein the flexible portion comprises a different polymer relative to other areas of the distal portion.
6. The lead of claim 4 , wherein the bias is configured maintain the one or more electrodes facing the heart of the patient.
