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 medical system includes a medical device and an analysis system. The medical device includes a perforation device having a shaft. The shaft has a proximal portion, and an opposed distal portion. A perforating tip is associated with the distal portion. At least a first light emitter is associated with the distal portion and is positioned proximate the perforating tip for illuminating a region surrounding the perforating tip. The analysis system is for analyzing returned light that is returned towards the shaft from the region surrounding the perforating tip. The analysis system includes a light sensor configured to detect one or more parameters of the returned light, a processor configured to perform an analysis of the one or more parameters, and an alert system connected to the processor for alerting a user to a result of the analysis.

System and method for carrying out a medical procedure

Methods and devices are disclosed for the formation of a communication between the aorta and left atrium. The method includes introducing a puncturing device, positioning the device at a location along the aorta, and advancing the puncturing device to create a pathway. The method may include: a. via an inferior artery, advancing a perforating tip of the puncturing device towards the aorta; b. positioning the perforating tip adjacent a wall of the aorta, proximate the left atrium; and c. advancing the perforating tip to perforate through the wall of the aorta and then through a wall of the left atrium, to create a pathway between the aorta and the left atrium, wherein the creation of the pathway can be confirmed with at least one of fluoroscopy, electro-anatomical mapping, pressure measurement, contrast injection, and echocardiograph.

Methods and devices for creation of communication between aorta and left atrium

An elongated medical sheath is configured to be movable and positionable proximate to a biological feature of a patient. An expandable-and-collapsible support structure is configured to be selectively movable, at least in part, between an interior of the elongated medical sheath and an exterior of the elongated medical sheath. An energy-emitting assembly is supported by the expandable-and-collapsible support structure.

Elongated medical sheath

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.
