John S. Ehlert has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220354471
    Abstract: An exemplary ultrasound biopsy device includes a probe and a holster. The probe is insertable into the holster to form a completed assembly. To assemble the probe to the holster, the probe is initially slid laterally onto the holster and then slid forward to latch the probe into engagement with the holster. The holster is coupled to a vacuum control module by one or more conduits and a power cable. The conduits and/or power cable may be retracted into the vacuum control module. The probe of the biopsy device includes a blade assembly at the distal end. The blade assembly comprises a blade that snaps onto a nosecone via a pair of resilient notched ends. A frictional fitting needle cover can be inserted over the needle and blade assembly to protect the user from the sharp blade.

  • Publication number: 20220240907
    Abstract: A biopsy device comprises a body, a needle, a cutter, and a tissue sample holder. The tissue sample holder comprises an outer cup and a cap. A tray retains severed tissue samples from a biopsy procedure. In some versions, the tray is selectively detachable from the cap in a one-handed operation by the user. The tray may be ejected into a sample container, such as a formalin cup. The cap may include a threaded portion that is configured to engage a complementary threaded portion of a sample container to seal the sample container once the tissue samples have been transferred to the sample container from the tissue sample holder of the biopsy device. One or more ports may be provided in the cap to manage excess fluid within the outer cup of the tissue sample holder, and/or to provide integrated access for a marker delivery device.

  • Publication number: 20220031291
    Abstract: A biopsy system includes various features. A tissue sample holder kit of the system comprises a rotatable member with chambers configured to receive tissue receiving features of a tissue sample tray. A biopsy device of the system includes user input features and user feedback features disposed on a body. A user interface of the system includes a graphical representation of a tissues ample holder. A biopsy site marker applier of the system includes markings associated with different biopsy device configurations. The biopsy system may undergo a multi-step initialization process. In operation, the biopsy system may execute pneumatic control algorithms including the use of vacuum, saline, and atmospheric air.
