Abstract

An adapter device that includes an adapter body having a first end and a second end. A connection interface is coupled to the first end, has a connection direction, and is configured to couple to a cardiac device. A receiving interface is disposed at the second end and has a receiving direction. The receiving interface includes a first receiving port that is in electrical communication with the connection interface and is configured to receive a first connector pin. A sealing member is configured to be sealably disposed over the receiving interface and configured to receive and frictionally engage at least a portion of the adapter body. In some embodiments, the connection direction and the receiving direction are the same. In some embodiments, the connection direction and the receiving direction are opposite.

12 . A method of using an implantable cardiac device, the method comprising: inserting a first connector pin into a first receiving port of a receiving interface on a second end of an adapter device, including inserting the first connector pin through a sealing member of the adapter device, wherein the receiving interface has a receiving direction that is defined as the direction the receiving interface is facing to receive the first connector pin; coupling the sealing member to the adapter device; coupling a first end of the adapter device to an implantable cardiac device, wherein the first end of the adapter device defines a connection interface having a connection direction, which is defined as the direction the connection interface is facing to receive the cardiac device, and wherein the receiving direction and the connection direction are the same; coupling the adapter device to an outside surface of a body of a subject; and applying a cardiac therapy from the implantable cardiac device for a period of time.
13 . The method of claim 12 , further comprising inserting a second connector pin into the second receiving port through the sealing member of the adapter.
14 . The method of claim 12 , further comprising coupling the implantable cardiac device to an outside surface of a body of a subject.
15 . The method of claim 12 , wherein the method further comprising securing the sealing member to the adapter device using a suture wire.
16 . The method of claim 12 , wherein the first end of the adapter device comprises an IS-1 or IS-4 configuration.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Provisional Patent Application No. 63/305,574, filed Feb. 1, 2022, which is incorporated herein by reference in its entirety.
