Abstract: A system for treating tissue includes an applicator having a bushing and a control member and a clip assembly having a capsule with a channel extending therethrough. The channel includes proximal and distal portions. The distal portion extends distally from the proximal portion and flaring outward in a single plane to form opposing flared sections. The assembly also includes clip arms include proximal ends slidably received within the channel to move the arms between tissue receiving and tissue clipping configurations. The assembly further includes a yoke including a distal portion connected to the arms and a proximal portion configured to be connected to the member so that longitudinal movement of the member relative to the capsule moves the arms between the tissue receiving and clipping configurations. The yoke is positioned in the capsule so that the yoke is deformable in the plane in which the capsule flares outward.

Abstract: A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

Abstract: The present disclosure relates to tissue traction devices and systems. In one example, a tissue tensioning system may include a filament having a first end comprising an attachment member, a second end, and a length therebetween extendable externally along a catheter. A first tissue fastener may be engageable with the attachment member and with a target tissue. The second end of the filament may be translatable to adjust a tensional force along the filament.

Abstract: The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue clip devices and related systems and methods. In an embodiment, a tissue clip may include a grasper including jaws at a first end, and a spring portion at a second end, and a longitudinal axis extending along a length of the grasper from the first end to the second end, wherein the spring portion is configured to bias the jaws toward each other. A wedge may be slidably disposed between the jaws such that an apex of the wedge is oriented toward the spring portion. A filament may be coupled to the wedge at a first end of the filament and may extend through a channel of the spring portion of the grasper to a second end of the filament.

Abstract: A system for treating tissue includes a clip assembly including a pair of clip arms, proximal ends of which are slidably received within a channel of a capsule to be moved between a tissue receiving configuration, in which distal ends of the clip arms are separated from one another, and a tissue clipping configuration, in which the distal ends are moved toward one another. The system also includes an applicator including a catheter and a control member extending therethrough. The control member configured to be connected to the clip arms to move the clip assembly between the tissue receiving and tissue clipping configurations. The system also includes a coupler attached to one of a proximal end of the capsule of the clip assembly and a distal end of the catheter, and configured to releasably couple the capsule and the catheter to one another.

Abstract: A system for treating tissue includes a clip assembly having a pair of clip arms. Proximal ends of the clip arms engage a distal portion of a central member slidably received within a channel of a capsule to be moved between an open configuration and a closed configuration. The central member includes the distal portion and a proximal portion connected to one another via a releasable connection which releases when subject to a force exceeding a predetermined threshold level. The system also includes an applicator releasably coupled to the clip assembly. The applicator includes an outer sleeve through which a control member extends. A distal end of the control member engages a cavity of the proximal portion to move the central member relative to the capsule. A lumen of the outer sleeve is sized and shaped to slidably receive the capsule therein.

Abstract: A medical device includes a shaft including a lumen configured to direct a flow of fluid through the shaft and an electrode. A proximal end of the electrode and a distal end of the shaft form a coupling configured to releasably couple the proximal end of the electrode with the distal end of the shaft. When the proximal end of the electrode is coupled to the distal end of the shaft, fluid delivered through the lumen is emitted from the electrode.

Abstract: According to one aspect, a tissue fastening device may comprise a body configured to include a plurality of fasteners; an anvil rotatable relative to the body; and a tissue cutting device. The body may define a longitudinal channel configured to receive the tissue cutting device. The tissue fastening device may further comprise a fastener actuator configured to move proximally relative to the body to deploy the plurality of fasteners from the body; and an actuation wire coupled to the tissue cutting device and the fastener actuator. The actuation of the actuation wire may cause the fastener actuator to deploy at least one of the plurality of fasteners into tissue distally of tissue cut by the tissue cutting device.
