摘要： A clipping device includes a clip including a capsule and a pair of clip arms movable between an open configuration and a closed configuration. A tension member includes a distal portion and a proximal portion, a pair of protrusions extending from opposing surfaces of the proximal portion to be received within openings extending through proximal ends of the clip arms, the proximal portion including a relief to define a pair of fingers separated from one another at proximal ends thereof. A yoke including a central portion including a recess formed at a distal end thereof, the recess sized and shaped to releasably receive the pair of fingers of the tension member, the pair of fingers configured to flex toward one another when a predetermined force is exerted thereon to release the pair of fingers from the recess and disengage the tension member from the yoke during deployment of the clip.

摘要： A device for delivering an agent may comprise a source of agent; a mixing chamber for receiving fluid and the agent; an outlet in fluid communication with the mixing chamber to deliver the fluid and the agent; and an actuator configured to (1) deliver a first flow of the fluid substantially free from the agent through the outlet; (2) after delivering the first flow, deliver a second flow of the fluid and the agent through the outlet; and (3) after delivering the second flow, deliver a third flow of the fluid substantially free from the agent through the outlet.

摘要： A clipping device includes a clip including a capsule and a pair of clip arms movable between an open configuration and a closed configuration. A tension member includes a distal portion and a proximal portion, a pair of protrusions extending from opposing surfaces of the proximal portion to be received within openings extending through proximal ends of the clip arms, the proximal portion including a relief to define a pair of fingers separated from one another at proximal ends thereof. A yoke including a central portion including a recess formed at a distal end thereof, the recess sized and shaped to releasably receive the pair of fingers of the tension member, the pair of fingers configured to flex toward one another when a predetermined force is exerted thereon to release the pair of fingers from the recess and disengage the tension member from the yoke during deployment of the clip.

摘要： A clipping device includes a capsule including a longitudinal body and a cap mounted over a distal end thereof so that the cap is movable relative to the longitudinal body from a pre-deployed configuration to a deployed configuration in which the cap, is moved proximally relative to the longitudinal body to reduce a length of the capsule. A channel of the cap and a channel of the capsule are substantially aligned with respect to one another. At least proximal portions of a pair of clip arms are received within the channels of the cap and the longitudinal body so that the clip arms are movable relative to the capsule between an open configuration, in which distal ends of the clip arms are separated from one another, and a closed configuration, in which the distal ends of the clip arms are drawn toward one another.

摘要： A medical device comprising a housing defining at least one enclosure for storing agent in a first form, a force applicator within the housing and adjacent the enclosure, a drive mechanism for moving the agent toward the force applicator, wherein the force applicator defines a surface for applying a force to the agent to separate the agent into particles smaller than a size of the first form, and wherein the device defines a lumen for receiving the particles from the force applicator and for receiving a pressurized fluid to propel the particles through the lumen.

摘要： A clipping device includes a clip including a capsule and a pair of clip arms, proximal ends of which are slidably received within the channel to move the clip arms between an open configuration and a closed configuration. Each of the pair of clip arms includes an elongated opening extending through the proximal ends thereof. A connector includes a central portion received between the proximal ends of the clip arms and a pin extending from the central portion receivable within the opening of each of the clip arms, the connector movable from an unlocked configuration, in which the pin is received within a distal portion of the elongated opening, to a locked configuration, in which the pin is received within a proximal portion of the elongated opening, when a predetermined force is applied thereto.

摘要： A device includes a clip including a capsule and a pair of clip arms, proximal ends of which are slidably received within a channel of the capsule to move the clip arms between an open configuration and a closed configuration. The clip arms are aligned relative to one another via a pin received within openings extending through proximal ends of the clip arms. A proximal portion includes a flexible shaft extending from a proximal end to a distal end including a bushing releasably coupled to the capsule. A control member extends longitudinally through the flexible shaft from a proximal end to a distal end releasably coupled to the proximal ends of the clip arms, the distal end of the control member including a pair of holding jaws, each of which include a pair of fingers extending about the pin along opposing sides thereof to grip the pin therebetween.
