  • Patent number: 10925667
    Abstract: An irrigated ablation catheter includes a tip electrode with a thin shell and a plug, defining a plenum chamber. The tip electrode has an inlet of a predetermined size and noncircular shape, and a predetermined number of outlet fluid ports having a predetermined diameter in the shell wall. The tip electrode thus considers a diffusion ratio of total fluid output area to fluid input area, a fluid port ratio, and a fluid inlet aspect ratio where the fluid inlet has a noncircular radial cross-section. The plenum chamber has a narrow proximal portion opening to a wider distal portion so that fluid pressure decreases while fluid velocity increases thereby increasing turbulence which decreases momentum for a more uniform distribution of fluid in the tip electrode. Extending distally from the plug is a baffle member shaped to diffuse fluid entering the tip electrode and to house an electromagnetic position sensor.

  • Patent number: 10918438
    Abstract: Systems, methods, and devices allow percutaneous mapping, orientation and/or ablation in bodily cavities or lumens. Such may include a structure that is percutaneously positionable in a cavity, such as an intra-cardiac cavity of a heart. Transducers carried by the structure are responsive to blood flow. For example, the transducers may sense temperature, temperature being related to convective cooling caused by blood flow. A controller discerns positional information or location, based on signals from the transducers. For example, blood flow may be greater and/or faster proximate a port in cardiac tissue than proximate tissue spaced from the port. Position information may allow precise ablation of selected tissue, for example tissue surround a port in the intra-cardiac cavity.

  • Patent number: 10881443
    Abstract: Devices and methods for shaping an ablation treatment volume formed in fluid enhanced ablation therapy are provided. The devices and methods disclosed herein utilize the interaction of fluids to create ablation treatment volumes having a variety of shapes. In one embodiment, a method for forming an ablation treatment volume having a desired shape includes delivering therapeutic energy to tissue to form an ablation treatment volume and simultaneously delivering a first fluid and a second fluid to the tissue. The first and second fluids can convect the therapeutic energy in a desired direction such that the ablation treatment volume has a desired shape.

  • Patent number: 10869717
    Abstract: Described here are devices and methods for forming a fistula between two vessels. In some instances, the fistula may be formed between a proximal ulnar artery and a deep ulnar vein. The fistula may be formed using an electrode, and may be formed with a first catheter placed in a first blood vessel and a second catheter placed in a second blood vessel. In some instances, access to the proximal ulnar artery may be achieved through a brachial artery, and access to the deep ulnar vein may be achieved through a brachial vein.

  • Patent number: 10850110
    Abstract: This accessory comprises a remotely steerable catheter (40) extended by a tip (50) comprising a base (52) to which the catheter (40) connects to and a cylindrical portion (54) defining a volume (56) suitable for housing the capsule (10). A sub-catheter (30) and the capsule are telescopically extendable with respect to the catheter between i) a retracted position and a deployed position wherein the capsule is removed from the connector and is carried by the distal end of the sub-catheter, and the distal end of sub-catheter and the proximal region (18) of the capsule being provided with disconnectable means of attachment (20, 36). The tip presents, between its base (52) and its cylindrical portion (54), a flexible portion (58) providing, between the base and the cylindrical portion, an elastic deformability in bending and compression.

  • Patent number: 10849674
    Abstract: An instrument for large-area ablation of the mucosa including at least one first gas supply line and at least one second gas supply line whose distal ends are arranged to form an acute angle (?), so that the ends diverge distally. A free space between the distal ends of the gas supply lines allows the user to view the tissue region behind the distal end of the instrument. Due to the acute angle (?), electrodes arranged at least partially in the ends of the gas supply lines generate a wide plasma beam with which the mucosa ablation can be performed. The instrument can be guided precisely due to the view through the free space. A connecting element according to the invention is provided for attaching the ends of the gas supply lines.

  • Patent number: 10842533
    Abstract: An electrode array and a delivery assembly are disclosed. The array is wrapped around a flexible core part of the delivery assembly. A sheath, also part of the delivery assembly, is disposed over the array and core. Steering cables extend through the core. Once the delivery assembly-encased array is inserted in the body, the combination is advanced to the tissue over which the array is to be deployed. By pulling on the steering cables the array and assembly are steered into position. Once the array is in position, the sheath is retracted, the array deploys over the target tissue.
