  • Patent number: 10688282
    Abstract: A medical device delivery system can be used to advance a medical device to a target area within a patient's vasculature. The system can comprise a catheter, a support sheath, and a core member coupled to a medical device. The core member can be used to longitudinally advanced or retracting medical device within a lumen of the support sheath. The support sheath can be advanced within the catheter until a distal end of the support sheath contacts or abuts a reduced diameter section of the catheter lumen. Thereafter, the core member can be advanced into the catheter lumen toward the target area.

  • Patent number: 10687843
    Abstract: An epidural space is cleared of fat and scar tissue in preparation for implantation of a medical lead by utilizing a clearing tool. The clearing tool has a flexible body that allows the clearing tool to deflect when entering the epidural space through a window in the vertebral bone and ligaments. The clearing tool is guided into the epidural space and to a target site by a guidewire present in the epidural space. Upon removal of the guidewire and clearing tool, the medical lead is inserted through the window and cleared epidural space until reaching the target site. The clearing tool may include a distal tip with a shape and size that aids in the clearing of the epidural space. The distal tip may be integral to the clearing tool or may be removable so as to allow for different sizes of the distal tip to be installed as needed.

  • Patent number: 10682152
    Abstract: A rapid exchange (RX) catheter may provide a proximal seal against a guide catheter inner lumen so that aspiration may be applied through a guide catheter. The catheter may include an exit port that defines a transfer port for aspiration and may enable minimal frictional engagement with the guide catheter proximal of the exit port. Aspiration can be applied to the lumen of the guide catheter and may be directed to and effective at the tip of the RX aspiration catheter. A tip of the RX catheter may facilitate aspiration and retrieval of the clot by expanding under load and can also partially or fully occlude the vessel.

  • Patent number: 10639107
    Abstract: A system and method for ensuring safe and tolerable insertion of a needle into a subject's body according to a preplanned or continuously monitored sequence of insertion steps. The system comprises a gripping device for gripping the needle in order to perform robotic insertion steps, yet for releasing the grip between such insertion steps, until the next insertion step is initiated. Thereby, the robot has full control of the needle during insertion steps, but does not constrain the needle between insertions, such that movement of the subject can cause neither damage nor discomfort. The gripping and insertion steps may be coordinated to keep in synchronization with the subject's breathing cycles, such that the insertion steps may be performed in the same segment of each cycle of motion of the subject's chest. The gripper can either fully disconnect from the needle, or can partially disconnect but constrain motion within limits.

    Abstract: The present embodiments provide a prosthesis deployment system, and method of deployment of a prosthesis using the same, having a positioning member at least partially disposed within a tubular segment of a tip assembly. The positioning member is movable between nondeployed and deployed configurations. In the nondeployed configuration the positioning member can permit the tip assembly to move relative to the enlarged body assembly. When an enlarged body is at a position farther away from a tip body, which may be at the edge of the tubular segment, the positioning member can move or flare to its deployed configuration to inhibit the enlarged body from moving relatively closer to the tip assembly. Axial force applied to the tip assembly during withdrawal of the tip assembly can be transmitted via the positioning member to the enlarged body assembly to facilitate its withdrawal from the body.

  • Patent number: 10463517
    Abstract: A controlled expansion stent graft delivery system has an adjustment configuration in which a retractable sheath is at a retracted position out of contact with a stent graft, but expansion of the stent graft is controlled by a control tether, which has a middle segment wrapped around a fabric tube of the stent graft. The stent graft changes diameter responsive to a tension level in the control tether. At least one of an orientation and a position of the stent graft may be adjusted during controlled expansion via the control tether.

  • Patent number: 10456554
    Abstract: A catheter for delivery of intraluminal and expandable devices. The catheter is provided with a flexible curved tip distal to the device loaded onto the catheter for delivery to a desired site within a body conduit. The curved distal tip causes the catheter to rotate to a preferred rotational orientation, which may be desirable for any device having asymmetric features, particularly when used in tortuous body conduits.

  • Patent number: 10456562
    Abstract: Devices, methods, and systems are provided for sealing a lung region. The target lung compartment is accessed and isolated via an isolation catheter. Fluid is delivered into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel. A sealing agent is injected into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel. Variables of air flow may be measured or analyzed prior to injection of the sealing agent, or the sealing agent may be introduced into the region after a suitable time has elapsed.

    Abstract: A delivery device according to principles described herein includes a catheter having three concentric shafts including an inner core, an outer sheath over the inner core and an outer support shaft at least partially extending over the inner core and the outer sheath. A timing belt having a plurality of belt teeth on a surface of the timing belt is coupled to an outer sheath over a medical device or stent on the inner core such that movement of the timing belt link causes movement of the outer sheath from its position over the medical device or stent. The delivery device is actuated by rotation of a thumbwheel a thumbwheel coupled to a barrel having a plurality of teeth such that rotation of the thumbwheel causes movement of the barrel such that the barrel teeth engage the belt teeth to cause movement of the timing belt causing movement of the outer sheath.

  • Patent number: 10449045
    Abstract: A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.

  • Patent number: 10441299
    Abstract: A catheter having a distal balloon and a deformable guidewire shaft of the catheter. The deformable guidewire shaft is adjacent to and external to the balloon. Inflation of the balloon bends the deformable guidewire shaft in order to orient or deflect a distal tip of the deformable guidewire shaft in a desired direction to guide and direct a guidewire extending through the deformable guidewire shaft towards a specific endovascular region. For example, it may be desired to orient the distal tip of the guidewire shaft towards a target vessel of a bifurcation or the balloon catheter may be used to bypass a Chronic Total Occlusion (CTO).
