摘要： A medical device configured to manipulate tissue within a body of a subject may include an elongate shaft having a proximal end and a distal end. The distal end of the shaft may be configured to be inserted into the body. The device may include end effectors coupled to the distal end of the elongate shaft. The end effectors may include a needle pivotably coupled to the shaft and configured to inject a fluid into the tissue. The end effectors may also include an articulating arm pivotably coupled to the shaft, and a cutting wire extending between the needle and the arm.

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 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 clipping system includes a clip, a core member and a control member. The clip includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, and clip arms. Proximal ends of the arms are slidably received within the channel to move the arms between open and closed configurations. The core member is received between and connected to the proximal ends of the arms to couple the arms to one another. The core member includes a locking feature movable between unlocked and locked configurations. The control member extends through a proximal portion of the system from a proximal end to an enlarged distal end housed within a proximal portion of the core member so that a longitudinal movement of the control member relative to the capsule moves the clip between the open and closed configurations.
