A medical device assembly for carrying out a cardiac procedure includes an ultrasound catheter having an elongate shaft including an ultrasound tip configured to emit ultrasound signals and receive reflected ultrasound signals. The assembly includes a sheath having an elongate member including a proximal portion, a distal portion having a distal end, a central portion between the proximal portion and the distal portion, and a catch for engaging the shaft of the ultrasound catheter. The central portion defines a longitudinal axis of the elongate member. The distal portion includes a curved section that spaces the distal end away from the longitudinal axis. The catch is configured to engage the shaft of the ultrasound catheter such that the shaft extends longitudinally along the central portion and the ultrasound tip is spaced longitudinally from the elongate member distal end.

Medical device assembly and related methods

A method for carrying out a cardiac procedure includes a. engaging a shaft of an ultrasound catheter with an elongate member of a medical sheath; b. positioning an ultrasound tip of the ultrasound catheter outside of a lumen of the elongate member; c. intravenously advancing the elongate member of the medical sheath towards a heart of a patient, to position a distal end of the elongate member adjacent a target anatomy within the heart; d. using the medical sheath as a guide to intravenously advance the ultrasound catheter towards the heart of the patient and position the ultrasound tip proximate the target anatomy; and e. using the ultrasound tip to image the target anatomy.

A stop-movement device is configured to be mounted to a first elongated medical assembly and a second elongated medical assembly. The stop-movement device has a body configured to stop, at least in part, relative movement between the second elongated medical assembly and the first elongated medical assembly.

Stop-movement device for elongated medical assembly

An elongated medical assembly is configured to be maneuverable proximate to a first biological feature of a patient. The elongated medical assembly is also configured to facilitate movement along an elongated length of the elongated medical assembly of a first medical device and a second medical device.

Elongated medical assembly

A medical sheath includes an elongate member having a proximal portion defining a proximal end and a distal portion defining a distal end. A first lumen extends through the elongate member and is open at the proximal and the distal end for passage of a medical device through the lumen. The medical sheath further includes an anchoring mechanism that is deployable from the elongate member. The anchoring mechanism includes an anchor that is removably securable to an anatomical feature to secure the elongate member to the anatomical feature, and a connector securing the anchor to the elongate member.
