Publication number: 20230233777Abstract: Various embodiments of a metered dose inhaler that includes a metering valve are disclosed. The inhaler includes a reservoir containing a pressurized formulation of medicament and carbon dioxide. The metering valve includes a metering chamber, a metering valve stem, and a metering valve stem seal having an opening through which the metering valve stem passes to form a dynamic seal between the metering valve stem and outside atmosphere. The metering valve stem seal has a Shore D hardness of 45 to 80 and its opening is adapted to be stretched wider by the metering valve stem passing through it than it would be absent the valve stem.Type: ApplicationFiled: November 18, 2020Publication date: July 27, 2023Applicant: KINDEVA DRUG DELIVERY L.P.Inventors: John P.

Patent number: 11707584Abstract: An inhaler (60) has a breath actuated trigger mechanism (100) reactive to an inhalation flow to trigger the release of a substance to be inhaled. The inhaler (60) has an inspiration flow which is subject to a higher degree of flow governing post-triggering than pre-triggering. This allows the triggering flow rate to be closer to, or even higher than, the governing flow rate of the inhaler.Type: GrantFiled: April 30, 2018Date of Patent: July 25, 2023Assignee: Kindeva Drug Delivery L.P.Inventors: Peter D. Hodson, Stephen J. Howgill
