Abstract: The present disclosure relates generally to apparatuses and methods for delivering an occlusion device to a paravalvular leak. In some embodiments, a paravalvular occlusion apparatus includes a catheter having main body including a proximal end and a distal end, a visualization element disposed in the distal end of the main body, and a working channel extending from the distal end of the main body. The catheter further includes an elongate shaft extendable from the working channel, wherein an occlusion device is coupled to the elongate shaft. In some embodiments, an occlusion device includes a leading end including a first section, and a trailing end opposite the leading end, the trailing end including a second section. The first section and the second section of the occlusion device are operable to be positioned along a perimeter of a prosthetic valve for blocking the paravalvular leak.

Abstract: Tissue puncture devices, and systems and methods for accessing tissue (e.g., cardiovascular tissue) according to the present disclosure may include a tubular sheath extending along a longitudinal axis, the tubular sheath having a proximal end and a distal end, a needle disposed coaxially in the sheath, the needle having a proximal end and a distal end and being movable along the longitudinal axis of sheath, and a needle control mechanism disposed at the proximal end of the needle, the needle control mechanism being configured to lock the distal end of the needle in a first position retracted within the distal end of the sheath, and release the needle to an unlocked second position such that the distal end of the needle is extendable beyond the distal end of the sheath.

Abstract: A spring element for a contact force sensing medical catheter. The spring element includes a first ring, a second ring spaced apart from the first ring, a plurality of struts connecting the first ring to the second ring, and a plurality of interlocking features. The second ring and the first ring are coaxially aligned with a longitudinal axis of the spring element. The plurality of struts is configured to permit elastic, relative axial and radial displacement between the first ring and the second ring. The plurality of interlocking features is configured to limit the relative axial and radial displacement between the first ring and the second ring.

Abstract: According to aspects of the present disclosure, a retrieval catheter assembly for retrieving an intragastric balloon may include a tubular member configured to pass through a wall of the intragastric balloon. The retrieval catheter assembly may also include a retrieval member coupled to the tubular member and movable between an undeployed configuration and a deployed configuration. In the undeployed configuration the retrieval member may be substantially aligned with the tubular member. In the deployed configuration at least a portion of the retrieval member may diverge from the tubular member and may be configured to engage the wall of the intragastric balloon.

Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as a heart valve, may include a delivery catheter having a distal end comprised of two or more rotatably coupled knuckles. An anchor delivery mechanism is disposed distally of the two or more knuckles, and includes a first pincer arm having a distal end and a proximal end rotatably coupled to a distal end of the anchor delivery mechanism at a first connection point, and a second pincer arm having a distal end and a proximal end rotatably coupled to the distal end of the anchor delivery mechanism at a second connection point opposite the first connection point. In a closed position, the distal ends of the first and second pincer arms are positioned together. In an open position, the distal ends of the first and second pincer arms are rotated apart from each other.
