Abstract
Implantation of a cardiac stimulus system using parasternal access to the ITV is provided. Superior access may be achieved using parasternal locations in the upper ribcage to access the ITV. Inferior access may be achieved using parasternal locations in the lower ribcage to access the ITV. Parasternal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance.
Claims20
A method of implanting a lead for use in a cardiac stimulus system in a patient, the lead having a proximal end and a distal end, with at least one electrode thereon;
- the method comprising:
- creating a subcutaneous tunnel from a first position in the patient to a second position in the patient and placing at least a first portion of the lead in the subcutaneous tunnel;
- inserting a second portion of the lead into an internal thoracic vein (ITV) to a desired parasternal location relative to the heart of a patient by accessing the ITV near the second position;
- and
- implanting an implantable pulse generator for use with the lead at the first position.
A method of treating a patient comprising delivering defibrillation therapy between a first electrode disposed on a lead and an implantable pulse generator, wherein:
- the lead comprises a first portion disposed in a subcutaneous, parasternal position and a second portion that extends into an internal thoracic vein (ITV) of the patient;
- and
- the first electrode is disposed on the first portion of the lead.
A method of implanting a lead parasternally for use in a cardiac stimulus system in a patient, the lead having at least one electrode thereon;
- the method comprising establishing access to an ITV through an intercostal space between two ribs, inserting a distal end of a lead into the ITV, advancing the lead to a desired location parasternally relative to the heart of a patient, and securing the lead in place.
