  • Publication number: 20240033085
    Abstract: A method for traversing an anatomical vessel wall of a subject is provided. The invention allows the crossing of a wire from one anatomical lumen, such as an artery, vein, esophagus, intestine or airway, through tissue, into another anatomical lumen, or cavity, or into a solid mass of tissue. In some aspects, the invention allows the crossing of a wire from the greater cardiac vein (GCV) into the left atrium without relying on another device in the left atrium to facilitate the crossing.

  • Publication number: 20220175530
    Abstract: Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

  • Patent number: 9452067
    Abstract: A mandrel for supporting a stent and rollers for pressing a radiopaque marker into a stent are disclosed. The mandrel can have a forward portion for carrying the stent and a rear portion for urging the stent forward portion into a gap between the rollers. The mandrel may be pushed or pulled into the gap, which is sized to allow the rollers to press the marker into engagement with the stent. Prior to moving the mandrel into the gap, the marker may be placed on a surface of the stent or partially inside a recess in the stent. Several markers can be efficiently and uniformly pressed onto the stent by moving the mandrel into the gap in one continuous movement in an axial or lateral direction. Markers can also be pressed onto the stent by placing the stent in the gap and rotating the stent about its central axis.

  • Publication number: 20150313661
    Abstract: A focal ablation assembly, used with an endoscope comprising an endoscopic tube, comprises a cryogenic catheter, a balloon and a reinforcing element. The cryogenic catheter is placeable within the endoscopic tube channel and has a distal end placeable at the distal end of the endoscopic tube. The balloon is mountable to the catheter distal end and extends distally of both of the distal ends. The reinforcing element at least partially defines the shape of the balloon in the expanded state. The balloon defines a balloon volume when expanded and has a thermally conductive therapeutic region which provides effectively no thermal insulation. In some examples the focal ablation assembly comprises a delivery catheter extending along the channel with a distal portion fluidly coupled to the balloon interior, whereby refrigerant can be introduced into the balloon interior and towards the therapeutic region by the delivery catheter.

  • Patent number: 9050073
    Abstract: A cryogenic ablation catheter includes a catheter shaft, a balloon and a connector respectively at the catheter shaft proximal and distal ends, a refrigerant delivery tube assembly including a refrigerant delivery tube rotatable within the catheter shaft lumen, and a refrigerant delivery element with an outlet located inside the balloon which directs refrigerant outwardly against the balloon at different rotary positions as it rotates. A cryogenic balloon ablation system includes the cryogenic ablation catheter, a catheter coupler mating with the connector, a motor including a rotatable hollow motor shaft, and a delivery line fluidly coupled to a cryogenic gas source for supplying cryogenic gas to the refrigerant delivery tube. At least one of the refrigerant delivery tube and the delivery line passes at least partway through the hollow motor shaft. The coupling tip of the connector and the refrigerant delivery tube rotate with the motor shaft.
