    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 tissue closure device includes a needle and a suture extending therefrom, a proximal head including a proximal slot and a proximal locking mechanism for releasably engaging a first end of the needle in the proximal slot in a first configuration, and a distal head movably coupled to the proximal head so that the proximal and distal heads are movable relative to one another between an open configuration, in which a target tissue is received therebetween, and a closed configuration, in which the target tissue gripped therebetween. The distal head includes a distal slot and a distal locking mechanism for releasably engaging a second end of the needle in the distal slot in a second configuration, the needle movable between the first and second configurations by rotating the needle, the needle alternatingly passed between the proximal and distal heads to thread the suture through the target tissue.

    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.
