Implantable medical devices with separate fixation mechanism
First Claim
1. An implantable apparatus comprising:
- a modular electrostimulation electrode assembly including;
a first module, including a fixation support member that is configured to fix the first module to a surface of a heart of a subject, the fixation support member defining a centrally located open portal that is configured for permitting electrode access to the surface of the heart therethrough, wherein the first module includes a first coupler feature;
a second module, including an electrostimulation electrode that is configured to contact the surface of the heart through the centrally located open portal of the fixation support member when the first module is coupled to the second module, wherein the second module includes a second coupler feature;
wherein the first and second coupler features are configured to be end user-attached securely to each other and end user-detached from each other to respectively attach the first and second modules to each other and detach the first and second modules from each other; and
wherein the second module is configured to remain attached to the first module via the first and second coupler features to provide electro-stimulation to the heart of the subject, and/or sense cardiac signals, via the electrostimulation electrode until such time as the end user detaches the second module from the first module and removes the second module from the heart of the subject while leaving the first module attached to the heart via the fixation support member of the first module.

Abstract
Devices or methods such as for stimulating excitable tissue or sensing physiologic response or other signals that can use separate fixation mechanism is described. An implantable apparatus can include a modular electrostimulation electrode assembly that can include a first module and a second module that can be end user-attachable to each other and end user-detached from each other. The first module can include an electrostimulation electrode fixation support member that can be laid flat against or otherwise conform to a surface of a heart, and can define a centrally located open portal such as for permitting electrode access to the surface of the heart. The second module can include an electrostimulation electrode that can be inserted through the portal of the fixation support member such as to contact the surface of the heart such as to deliver chronic electrostimulation to the heart.
