Abstract: A method for determining a recovery voltage in a battery includes detecting a transient increased current draw event drawing current from the battery, the transient increased current draw event starting at a start time and ending at an end time; and in response to detecting the transient increased current draw event, waiting until time and/or voltage criteria are met to determine recovered battery voltage. An implantable pulse generator (PG) device for stimulating a human organ includes a battery, a power sink drawing current from the battery, wherein drawing increased current from the battery for transient periods causes battery voltage to decrease; and a status indicator detecting a transient increased current draw event and waiting a minimum time duration after the transient increased current draw event to measure battery voltage in order to determine a recovery voltage.

Abstract: This document describes, among other things, a method of operating a medical device comprising updating a regulatory approval status stored in at least one of the medical device or a second device operable to communicate with the medical device, and enabling or disabling the at least one function in the medical device based on the regulatory approval status. The regulatory approval status corresponds to at least one function performable by the medical device.

Abstract: This document discusses, among other things, contrasted components for a medical device, and methods of making and using contrasted components. An example device includes a header including an opening configured to receive a set screw and a plug, and an insulative component, such as a plug or sleeve, that is insertable in the opening over the set screw. The insulative component has a visible exterior surface that is visually contrasted from a portion of the header proximate the opening. An example method includes forming from a first material a medical device header block having an opening configured to receive a plug, adding a marker to the first material or a second material, and forming from the second material a plug insertable in the opening. The marker in the second material creates or enhances a visual difference between the first material and the second material.

Abstract: An apparatus and method for determining the condition of a battery in an implantable cardiac rhythm management device is described. A battery's status is determined from a record of the device's operational history. The operational history may include the total number of events or event durations recorded during a specified time period. The battery charge consumption is then estimated by means of charge coefficients associated with each type of event.

Abstract: One aspect relates to a method to provide trended measurement of cardiac resynchronization therapy (CRT). In various embodiments of the method, data related to a status of a prescribed cardiac resynchronization therapy (CRT) in a cardiac rhythm management (CRM) device is recorded, and the data is processed into trended data useful for assessing the status of the prescribed CRT. The trended data is presented for use to assess the status of the prescribed CRT and assist with determining programming adjustments for improving the prescribed CRT. Other aspects are provided herein.
