The present technology is directed to adjustable interatrial shunting systems that selectively control blood flow between the left atrium and the right atrium of a patient. The adjustable interatrial devices include a shunting element having an outer surface configured to engage native tissue and an inner surface defining a lumen that enables blood to flow from the left atrium to the right atrium when the system is deployed across the septal wall. The systems can include an actuation assembly for selectively adjusting a geometry of the lumen and/or a geometry of a lumen orifice to control the flow of blood through the lumen.

Adjustable shunts and associated systems and methods

The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes a method for monitoring a shunting element implanted in a patient and having a lumen fluidly coupling cavities of the patient's heart. The method can comprise obtaining first and second radiographic images of at least two radiopaque elements associated with the lumen of the shunting element. A spatial relationship between the radiopaque elements varies according to a size of the lumen. The first radiographic image can be taken from a first viewing angle and the second radiographic image can be taken from a second viewing angle generally orthonormal to the first viewing angle. The method also includes determining the size of the lumen based, at least in part. on locations of the radiopaque elements in the first and second radiographic images.

Systems and methods for radiographic monitoring of shunts

A device for closing a tissue opening includes a proximal housing portion having a first portion, a second portion, a third portion, and a fourth portion. The first portion and the fourth portion extending transversely to a longitudinal axis of the proximal housing portion on opposite sides of the proximal housing portion. A distal portion extends from the proximal housing portion. At least the second portion and the third portion are configured to move toward the first portion.

Clip applier and methods of use

The present technology includes systems and methods for invasively adjusting implantable devices for selectively controlling fluid flow between a first body region and a second body region of a patient. For example, in many of the embodiments described herein, a catheter can be used to mechanically and/or electrically engage an implanted medical device. Once the catheter engages the medical device, the catheter can (i) increase a dimension associated with the medical device, such as through mechanical expansion forces, and/or (ii) decrease a dimension associated with the medical device, such as by heating a shape memory component of the medical device above a phase transition temperature.

Adjustable implantable devices and associated methods

The present technology relates to intracardiac sensors and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include an implantable capacitor having a capacitance value that is variable based on the pressure within the patients heart and a sensing circuit configured to measure the capacitance value. The device can also include an implantable inductor and a power circuit configured to wirelessly receive power from an external source via the inductor. When the device is in a first configuration, the capacitor can be electrically coupled to the sensing circuit and the inductor can be electrically coupled to the power circuit. When the device is in a second configuration, the capacitor can be electrically coupled to the inductor to form a resonant circuit.

Intracardiac sensors with switchable configurations and associated systems and methods

A system having an elongate assembly, an expandable assembly having a fixed end region and a movable end region, the expandable assembly selectively transitioning between an expanded state and an unexpanded state with movement of the movable end region towards the fixed end region, and an advancement aid extending distally from the expandable assembly.

A vessel closure device delivery system including a delivery device that couples to a vessel closure clip for delivering the clip onto a blood vessel and a retractable vessel locator is removeably attached to the delivery device, the distal end of the vessel locator being adapted to transition from a collapsed state suitable for insertion into a vessel and an expanded state that lodges against a wall of the vessel from inside the vessel.

An apparatus for delivering a clip includes an introducer sheath including an outer surface extending between its proximal and distal ends. A clip is carried on the outer surface, e.g., on a carrier assembly that is slidable along the outer surface from the proximal end towards the distal end. A skin overlies the outer surface of the sheath and the carrier assembly that is separable from the outer surface as the carrier assembly is advanced from the proximal end towards the distal end of the sheath. During use, the distal end of the sheath is inserted into an opening through tissue, e.g., into a puncture communicating with a blood vessel. The carrier assembly is advanced towards the distal end of the sheath, causing the skin to separate from the outer surface of the elongate member, and the clip is deployed from the carrier to seal the opening.

Sheath apparatus and methods for delivering a closure device

A method for delivering a closure element to an opening formed in a wall of a body lumen. The method includes inserting a distal end region of an apparatus into the opening in the wall of the body lumen, moving a third grasping portion toward the first grasping portion to limit movement of the distal end of the apparatus relative to the opening in the wall of the body lumen, and moving a second grasping portion toward the first grasping portion to advance the closure element distally. The second grasping portion and third grasping portion are movable toward the first grasping portion.

A surgical device of suturing vascular vessels is described, as well as methods for suturing tissue employing the surgical device. In one form the device includes a distal member that contains a suture and needle engaging fitting. A needle is advanced through tissue adjacent the puncture wound and into the needle engaging fitting to draw lengths of suture material which can then be used to close the puncture wound. In another form the device includes a needle advanceable through tissue and into a needle capture element within a distal end of the surgical device to draw lengths of suture material which can then be used to close various puncture wounds. In still another form the device includes at least one needle advanceable to draw lengths of suture material to close various puncture wounds. A foot is pivotal between a non-deployed and a deployed position.

Vascular suturing device

A closure system and methods of use are provided for use in sealing an opening in a body tissue, such as a vascular puncture site. A method of closing the opening in the body tissue can be performed with the closure system having a closure clip. The method can include positioning the closure clip in a first closure clip position adjacent to the opening in the body tissue such that a plurality of spikes of the closure clip are inserted into the tissue at a location outward from a central axis of the opening. Subsequently, the closure clip can be positioned in a second closure clip position such that the plurality of spikes are pulled inward toward the central axis of the opening so as to pull the tissue between the opening and each of the spikes together and close the opening.
