Abstract

A biostimulator system includes a biostimulator having a header module and a housing module. The header module includes a fixation element, a pacing electrode, and an electrical pin. The housing module includes pacing circuitry that is electrically connected to a power source, and an electrical socket to receive and electrically connect the electrical pin to the pacing circuitry. The biostimulator system includes a biostimulator transport system to deliver the header module to an interventricular septal wall and to deliver the housing module to a ventricular chamber. The modules are then electrically connected within the ventricular chamber. Other embodiments are also described and claimed.

First claim

What is claimed is:

1 . A biostimulator, comprising:
a header module including a fixation element, a pacing electrode, and an electrical pin electrically coupled to the pacing electrode; and a housing module including pacing circuitry electrically coupled to a power source, and an electrical socket to receive and electrically couple the electrical pin to the pacing circuitry.

2 . The biostimulator of claim 1 further comprising an attachment mechanism to mechanically couple the header module to the housing module.

3 . The biostimulator of claim 1 , wherein the housing module includes a guide lumen radially offset from a housing axis of the housing module.

4 . The biostimulator of claim 3 further comprising a guide rail coupled to the header module, wherein the guide rail extends through the guide lumen of the housing module.

5 . The biostimulator of claim 3 , wherein the electrical socket is within the guide lumen.

6 . The biostimulator of claim 1 , wherein the header module includes a header leadlet electrically coupled to the pacing electrode, wherein the housing module includes a housing leadlet electrically coupled to the pacing circuitry, and further comprising a cable connector interconnecting the header leadlet and the housing leadlet.

7 . The biostimulator of claim 1 , wherein the fixation element includes a helical anchor.

8 . A biostimulator system, comprising:
a biostimulator transport system; and a biostimulator mounted on the biostimulator transport system, wherein the biostimulator includes
a header module including a fixation element, a pacing electrode, and an electrical pin electrically coupled to the pacing electrode, and
a housing module including pacing circuitry electrically coupled to a power source, and an electrical socket to receive and electrically couple the electrical pin to the pacing circuitry.

9 . The biostimulator system of claim 8 , wherein the biostimulator transport system includes a guide rail coupled to the header module.

10 . The biostimulator system of claim 8 , wherein the biostimulator transport system includes a guide shaft coupled to the header module, and wherein the guide shaft is electrically coupled to the pacing electrode.

11 . The biostimulator system of claim 8 further comprising an attachment mechanism to mechanically couple the header module to the housing module.

12 . The biostimulator system of claim 8 , wherein the housing module includes a guide lumen radially offset from a housing axis of the housing module.

13 . The biostimulator system of claim 8 , wherein the header module includes a header leadlet electrically coupled to the pacing electrode, wherein the housing module includes a housing leadlet electrically coupled to the pacing circuitry, and further comprising a cable connector interconnecting the header leadlet and the housing leadlet.

14 . A method, comprising:
delivering a header module of a biostimulator to an interventricular septal wall; delivering a housing module of the biostimulator to a ventricular chamber; and electrically coupling the header module to the housing module within the ventricular chamber.

15 . The method of claim 14 further comprising mechanically coupling the header module to the housing module within the ventricular chamber.

16 . The method of claim 14 , wherein delivering the housing module includes tracking the housing module over a guide rail to the header module.

17 . The method of claim 16 , wherein the guide rail extends through a guide lumen of the housing module, and wherein the guide lumen is radially offset from a housing axis of the housing module.

18 . The method of claim 16 , wherein tracking the housing module includes advancing a guide catheter over the guide rail to push the housing module toward the header module.

19 . The method of claim 14 , wherein electrically coupling the header module to the housing module includes interconnecting, by a cable connector, a header leadlet of the header module to a housing leadlet of the housing module.

20 . The method of claim 19 further comprising delivering the cable connector onto the header leadlet and the housing leadlet within the ventricular chamber.
