{{AFC comment|1=It's painfully obvious to me that this article's author has absolutely no clue about this company or its field of endeavor, and is likely paid to mash a bunch of links together to get on WP.

Revision as of 20:23, 23 December 2020

  • Comment: This draft was resubmitted rapidly, within a few hours, after being declined, with only minor changes. Resubmitting a draft too rapidly after it was declined is not useful and is not likely to result in approval. When a draft that has been declined is resubmitted, the reviewers look at the history, and expect that the submitter will attempt to address the concerns of the reviewers. If the submitter is not sure what the reviewer wants, it would be a good idea to discuss with the reviewer rather than just resubmitting (and annoying the reviewers).
    You may ask for advice on how to improve this draft at the Teahouse or on the talk pages of any of the declining reviewers. (The declining reviewers may advise you to ask for advice at the Teahouse.)
    The author is very strongly advised to discuss with the reviewers, or at least to rework this draft substantially, rather than just resubmitting.
    If this draft is resubmitted rapidly again, it is likely to be rejected, and it may be nominated for deletion, or a topic-ban may even be requested against further submission by the responsible editor.
    Does the author of this draft have any sort of financial or other connection with the subject of this draft? Please read the conflict of interest policy and the paid editing policy and make any required disclosures.
    You may ask for advice about conflict of interest at the Teahouse.
    If this draft is resubmitted without addressing the question about conflict of interest, it may be Rejected or nominated for deletion.
    This draft still reads as if it was written by the company. Robert McClenon (talk) 21:46, 29 November 2020 (UTC)
  • Comment: The title of this draft has been disambiguated.
    If this draft is accepted, a hatnote will need to be added to the primary page to refer to this page.
    The primary page is Umbra, penumbra and antumbra. Robert McClenon (talk) 21:43, 29 November 2020 (UTC)

Penumbra, Inc. is a medical device company[1][2] headquartered in Alameda, California.[3][4] The company was founded by Arani Bose and Adam Elsesser in 2004.[5] It manufactures devices for interventional therapies to treat vascular conditions such as stroke and aneurism.[6]

History

Penumbra initially focused on treatments for ischemic stroke.[7] In 2019 the first patient was enrolled in a study of mechanical power-aspiration for thrombus removal in coronary vessels.[8] In 2018 the company acquired 40% of the outstanding shares of virtual reality joint venture MVI Health[clarification needed] from collaborator Sixense[clarification needed], boosting its interest to 90%.[9] In 2017 the company acquired the Italian distrubutor Crossmed S.p.a.[clarification needed][10]

Criticism of Penumbra

Criticism of Penumbra has followed various aspects of its products and business practices. In 2016 a lawsuit claimed the Penumbra Coil 400 caused brain damage after surgery.[11] The company's specialized catheter has been linked to the deaths of stroke patients, and it is (allegedly) a target of short sellers.[12][13][14] A request has been sent to The SEC and U.S. Food and Drug Administration launch an investigation.[15] A scientist who has published research articles showing the reliability of Penumbra's medical products is (allegedly) an internet fabrication.[16]

Recalls

In 2011 the company recalled its Penumbra Coil 400.[17] In 2017 the company recalled a 3D revascularization device.[18] In 2020 the company recalled one of its catheter used during heart surgery due increased risk of mortality and serious injury.[19][20][21]
