Abstract: In some examples, a catheter assembly includes a delivery catheter defining a delivery catheter lumen, a delivery catheter handle connected to the delivery catheter, a retrieval catheter defining a retrieval catheter lumen configured to receive the delivery catheter, and a retrieval catheter handle connected to the retrieval catheter. A proximal end of the retrieval catheter handle is configured to removably couple to a distal end of the delivery catheter handle.

Abstract: In some examples, a thrombus removal device includes an elongated support member and an expandable element configured to segment the thrombus into smaller pieces as the thrombus moves into a basket defined by the expandable element. The expandable element is configured to expand radially outward from a delivery configuration to a deployed configuration. In the deployed configuration, the expandable element defines a proximal mouth configured to receive a thrombus and a distal basket configured to receive at least part of the thrombus after it has moved through the proximal mouth. A proximal portion of the expandable element defines a plurality of arms configured to segment the thrombus into smaller pieces.

Abstract: A computer system includes processor hardware configured to execute instructions from memory hardware. The instructions include training a machine learning model to generate an entity expiration likelihood output, obtaining a set of multiple database entities, and processing, by the machine learning model, feature vector inputs associated with each database entry to generate an entity expiration likelihood output. The instructions include determining a subset of the database entities having the highest entity expiration likelihood outputs, and, for each database entity in the subset, determining output impact scores for parameters of the feature vector input associated with the database entity, generating a feature list based on the determined output impact scores, and automatically selecting an executable sequence according to the entity expiration likelihood output associated with the database entity.
