US Classification:

62 66, 220752

Abstract:

A container for storing a biopharmaceutical drug product is disclosed. The container includes two surface area planar walls. A plurality of smaller side walls circumscribing each, of the planar walls. The container may also include a plurality of members extending between the first planar surface and the second planar surface and located at spaced apart locations on each of the first and second planar surfaces. A method of freezing at least one biopharmaceutical product in the container is also disclosed.

Abstract:

This disclosure is directed to devices, systems, and techniques for identifying a respiration rate based on an impedance signal. In some examples, a medical device system includes a medical device including a plurality of electrodes. The medical device is configured to perform, using the plurality of electrodes, an impedance measurement to collect a set of impedance values, where the set of impedance values is indicative of a respiration pattern of a patient. Additionally, the medical device system includes processing circuitry configured to identify a set of positive zero crossings based on the set of impedance values, identify a set of negative zero crossings based on the set of impedance values, and determine, for the impedance measurement, a value of a respiration metric using both the set of negative zero crossings and the set of positive zero crossings.

International Classification:

A61N 1/36
A61N 1/372

Abstract:

A medical device system and associated method determine an implantable medical device state prior to implantation. An impedance monitoring module monitors for a change in impedance between a pair of electrodes coupled to the impedance monitoring circuit. The system includes an enclosure for carrying the implantable medical device. The enclosure has a surface having an electrical impedance. A control module is configured to detect one of a first pre-implant state and a second pre-implant state of the implantable medical device in response to the impedance monitoring module detecting a change in impedance between the electrodes and adjust operation of the implantable medical device in response to detecting the impedance change.
