Abstract: Disclosed embodiments include apparatuses, systems, and methods for coupling devices. In an illustrative embodiment, an apparatus includes a locking body defining an opening with a first section having a first width and a second section having a second width smaller than the first width. The locking body is slidably mountable on a first device with a first coupling to receive a second coupling having a flange with a width that is smaller than the first width and larger than the second width. A slidable mounting mechanism slidably secures the locking body on the first device. The locking body slides between an open position, in which the first section is positionable to enable the first coupling to receive the second coupling, and a closed position in which an edge of the locking body around the second section abuts the flange to prevent withdrawal of the second coupling.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices, systems, and methods for controlled volume ablation of tissue. In one example, a catheter may include an elongated member having a distal end extending along a longitudinal axis. A first electrode may extend along the elongated member. The first electrode may have a distal portion arranged on a circumferential surface about the longitudinal axis at the distal end. A second electrode may extend along the elongated member. The second electrode may have a distal portion arranged on the circumferential surface about the longitudinal axis at the distal end of the elongated member. A sheath may be slidably disposed about the elongated member. The sheath may be configured to change position by sliding along the member to insulate a portion of one or both of the first and second electrode.

Abstract: A medical device can include an elongate outer member and an elongate inner member in the elongate outer member. The elongate outer member defines a first lumen and includes a lateral suction port that is in fluid communication with the first lumen. The elongate inner member is rotatable relative to the elongate outer member and defines a second lumen. The second lumen includes an opening at a distal end of the elongate inner member to allow passage of fluid into the second lumen. The elongate inner member has a first lateral passage where the first lateral passage is rotatable into partial alignment with the lateral suction port to provide or control suction or other fluid communication between the lateral suction port and the second lumen. The medical device also has an electrode at a distal end of the inner member.

Abstract: A catheter includes an inflatable balloon for insertion into an organ of a patient, one or more electrodes and a coil. The one or more electrodes are disposed on a surface of the inflatable balloon and are configured to be placed in contact with tissue of the organ, and to perform at least one of: (i) sensing one or more electrical signals from the tissue, and (ii) applying one or more ablation pulses to the tissue. The coil is disposed on the surface of the inflatable balloon, and is configured to output a signal indicative of at least one of: (i) a temperature of the tissue, and (ii) a magnetic field indicative of a position of the catheter in the organ.

Abstract: The invention relates to an ablation catheter for treatment of a patient's tissue, for example for a PVI procedure on a patient's heart, comprising an elongated catheter shaft and an ablation portion being arranged at a distal end of the catheter shaft with a plurality of electrodes accommodated along the ablation portion, wherein the ablation portion comprises at least two loop sections forming a three-dimensional spiral. In order to increase safety of ablation treatment, spare adjacent tissue (e.g. nerves, vessels, esophagus) and shorten ablation time, a pitch, or clearance of two neighboring loop sections is greater than an ionization threshold of the medium around the distal section, for example blood or gases resulted from electrolysis. The invention further relates to an operation method of such ablation catheter.

Abstract: A catheter with a variable circular loop responsive to a contraction wire for coiling is supported by a member having a tapered distal section that transitions from a circular cross-section to a generally rectangular cross-section while maintaining a uniform cross-sectional area along the entire tapered length for improved coiling characteristics. A radially constrictive sleeve prevents separation of the contraction wire from the support member to minimize misshaping of the loop during contraction.
