Business Combinations [Abstract]
Acquisitions	4. Acquisitions. During January 2023, we paid $2.0 million to acquire shares of Series Seed-1 Preferred Stock of Solo Pace Inc. ("Solo Pace"), owner and developer of a temporary external pulse generator and grounding pad with associated remote control module. Our investment has been recorded as an equity investment accounted for at cost and reflected within other assets in the accompanying consolidated balance sheets because the equity interest does not have a readily determinable fair value and because we are not able to exercise significant influence over the operations of Solo Pace. Our investment in Solo Pace represents an ownership of approximately 19% of its outstanding capital stock.

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).
