The present disclosure is related to a device for gripping catheters that are used in interventional cardiac procedures without causing internal catheter damage. The present disclosure will allow the operator to maintain improved stability and maneuverability compared with current approaches, including, primarily, digital manipulation, which can lead to fatigue, instability and inappropriate catheter movement. Specifically in the pediatric population where small movements can lead to severe and permanent complications, the present disclosure has the potential to increase the safety profile of already high-risk interventional catheterization and electrophysiology procedures.

Systems, methods, and devices for performing heart procedures include a multi-functional catheter with a multi-lumen arrangement. The multi-lumen arrangement includes a central lumen formed by an inner tube with multiple pressure channels embedded in the wall of the catheter. The central lumen has a first end hole terminating at a distal end of the multi-functional catheter. The outer lumen has one or more second side holes. Moreover, a welded tip can maintain a consistent diameter for the distal end. Multiple radiopaque markers can identify various portions of multi-functional catheter to aid in positioning the lumens at different placements in the heart and / or crossing the aortic valve. Accordingly, multiple diagnostic procedures can be performed with the multi-functional catheter, such as a coronary angiogram and a trans-valvular pressure gradient measurement, while omitting reliance on additional catheters or a digital console system.

Systems and methods are provided for treating conditions such as heart failure and / or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and / or after deploying a VAD.

The present disclosure directs a catheter extension / pre-dilation system including an outer delivery sheath, an inner member extending within the sheath, and a mechanism for engaging and disengaging the inner member to the sheath. The inner member is configured with a tapered distal tip having a delivery microcatheter and a pre-dilation balloon member attached to the tapered distal tip near the microcatheter. The outer delivery sheath and the inner member are retrofitted for different engagement / disengagement mechanisms. The delivery microcatheter provides improved crossability for the balloon member to the treatment site in a non-invasive, quick and convenient manner. During a cardiac procedure, a guidewire and a guide catheter are advanced to the vicinity of the treatment site within a blood vessel. Subsequently, the inner member and the outer delivery sheath are advanced along the guidewire within the guide catheter to the treatment site in their engaged configuration. Once at the treatment site, the balloon member is inflated for pre-dilation treatment. Subsequently, the inner member is disengaged from the outer delivery sheath and retracted from the outer delivery sheath, and a stent is delivered to the treatment site within the outer delivery sheath.

A method of machine-assisted setting up of a procedure for conduction system pacing in a patient with a heart, comprising: (a) identifying a conduction system location on an image data set of said heart, said image acquired using data collection from outside the heart; and (b) providing machine-assisted guidance of a pacemaker electrode placement to a target location associated with a portion of said conduction system in said heart, said target location suitable for capture of said conduction system by pacing with a pacing pulse from said lead.

An example method includes receiving first imaging data for a region of interest and segmenting first and second anatomical structures on the first imaging data. The method also includes determining relative positions of the first and second anatomical structures on the first imaging data based on the segmented first and second anatomical structures. The method additionally includes receiving second imaging data for the region of interest and segmenting the first anatomical structure on the second imaging data to determine an additional segmented first anatomical structure. The method further includes registering the first imaging data with the second imaging data based on the segmented and additional segmented first anatomical structures. Additionally, the method includes displaying the second anatomical structure based on the second imaging data, the relative positions of the first and second anatomical structure on the first imaging data, and the additional segmented first anatomical structure.
