The instant disclosure relates to electrophysiology catheters for tissue ablation. In particular, the instant disclosure relates to a cryogenic ablation balloon with a catheter handle that interfaces with capital equipment.

Pulmonary vein isolation balloon catheter

Aspects of the present disclosure are directed to flexible catheters for both electrophysiology mapping and ablation using a high-density array of electrodes. These catheters may be used to detect electrophysiological characteristics of tissue in contact with the electrodes, and conduct monopolar and bipolar ablations of the tissue.

Radio-frequency ablation and direct current electroporation catheters

Various embodiments of the present disclosure can include a medical device for providing therapy to heart tissue. The medical device can comprise a balloon, a movable manifold, wherein the movable manifold comprises a first plurality of openings and the movable manifold is inside the balloon and the movable manifold is configured to distribute a fluid within the balloon, an elongate shaft with a proximal end portion and a distal end portion, wherein the distal end portion of the elongate shaft is coupled with the balloon, a central lumen, wherein the movable manifold is movably coupled with the central lumen, and a supply lumen comprising a supply lumen proximal end and a supply lumen distal end, wherein the supply lumen is longitudinally movable and in fluid communication with the movable manifold, wherein the movable manifold is configured to move longitudinally in response to an actuation of the supply lumen proximal end.

Apparatus and system for cryo-therapy balloon

An elongate medical device having a device longitudinal axis and a device distal region, the medical device comprising a balloon at the device distal region and having a balloon longitudinal axis, the balloon comprising a balloon inflatable portion with a first length configured to transition from a deflated state to an inflated state and includes a portion of the balloon proximal portion and a portion of the balloon distal portion, a balloon proximal portion with a second length, a balloon distal portion with a third length, wherein, in the inflated state, the balloon is symmetrical about the balloon longitudinal axis and the balloon comprises a first profile shape with a second length and a second profile shape with a third length, and wherein the balloon distal portion comprising the second profile shape comprises a tissue contacting surface where a substantial portion of the tissue contacting surface is concave.

An electrode assembly includes an electrode pair including a first electrode and a second electrode configured to be selectively energized for delivery of electroporation therapy. The electrode assembly also includes an expandable isolation member disposed axially between the first electrode and the second electrode. One of the first electrode and the second electrode is positioned proximally of a proximal end of the expandable isolation member and the other of the first electrode and the second electrode is positioned distal to a distal end of the expandable isolation member. The expandable isolation member is configurable between a collapsed configuration and an expanded configuration. The expandable isolation member includes a circumferential sealing surface configured for sealing engagement with tissue of a patient such that the expandable isolation member inhibits fluid and electrical communication between the first electrode and the second electrode when engaged with the tissue.

Electrode assembly including expandable isolation member

Embodiments include medical devices comprising a handle assembly including a wire tensioner component and an adjustment knob, the adjustment knob configured to rotate about a longitudinal axis of the handle assembly; an elongate shaft coupled to the handle assembly, the elongate shaft defining a lumen and including a deflectable section; a first wire coupled to the adjustment knob and extending from the adjustment knob through the lumen to at least a distal end portion of the deflectable section; and a second wire coupled to the wire tensioner component and extending from the wire tensioner component to at least the distal end portion of the deflectable section, the second wire having a deflectable extraluminal section configured to deflect independently of the deflectable section.

Esophageal deviator

The instant disclosure relates to electrophysiology catheters for tissue ablation. In particular, the instant disclosure relates to a cryogenic ablation balloon with safety features that facilitate identification of a leak into an interstitial space between inner and outer balloons as part of the ablation balloon catheter assembly, and prevents egress of cryogenic fluid out of the ablation balloon.

The instant disclosure relates to electrophysiology catheter for tissue ablation. In particular, the instant disclosure relates to a system controller for facilitating an ablation therapy at a cryogenic ablation balloon. In an embodiment, an ablation an ablation catheter system comprising a catheter shaft including proximal and distal ends, a catheter handle coupled to a proximal end of the catheter shaft, a cryogenic ablation ballon coupled to the distal end of the catheter shaft, the ablation ballon configured and arranged to deliver a cryogenic ablation therapy to target tissue, an ablation system controller coupled to the catheter handle.

Cryogenic ablation system

An elongate medical device shaft may comprise an elongate body and an annular electrode disposed on the elongate body. The annular electrode may define a longitudinal axis and have an outer diameter. The outer diameter may be greater at an axial center of the electrode than at an axial end of the electrode. Additionally or alternatively, the elongate body may comprise three longitudinal sections having three wall thicknesses. The middle wall thickness may be less than the proximal and distal wall thicknesses and the distal wall thickness may be less than the proximal wall thickness. Additionally or alternatively, the shaft may comprise an inner cylindrical structure and an outer tube. The outer tube may comprise a first radial layer and a second radial layer that is radially-outward of the first radial layer, the first radial layer, second radial layer, and inner structure having different stiffnesses.
