Abstract: The present disclosure relates generally to the field of medical devices for treating heart disease. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. A system for delivering a chordae tendineae into a heart may include a delivery catheter. A clamp catheter may be configured to translate through the delivery catheter. A spreader may be disposed on the clamp catheter. A first clamp may be at least partially contained in the spreader in a closed configuration and may be attached to the chordae tendineae. An anchor catheter may be configured to translate through the delivery catheter and may have an anchor attached to the chordae tendineae. A sheath may be extended over the anchor catheter and anchor and may be configured to restrain an arm of the anchor.

Abstract: This document provides medical device systems and methods for obtaining tissue samples. For example, this document provides medical device systems and methods for transbronchial needle biopsy tissue acquisition. In some cases, a needle biopsy system includes an actuator device, an outer needle with a lumen therethrough, and an inner needle at least partially disposed within the lumen. The outer needle can extend distally from the actuator device. A distal tip of the inner needle can be capable of being fully disposed within the lumen. The inner needle can extend distally from the actuator device. The actuator device can be configured to translate the outer needle proximally and distally. The actuator device can be configured to translate the inner needle proximally and distally independently of the outer needle.
