摘要： An example medical device is disclosed. The example medical device includes a shaft having a proximal end region, a distal end region and an outer surface. The medical device also includes a hemostasis clip coupled to the outer surface of the distal end region of the shaft, wherein the hemostasis clip is configured to shift between an open position and a closed position. Further, the medical device includes a tension member coupled to the hemostasis clip, wherein actuation of the tension member shifts the hemostasis clip between the open position and the closed position.

摘要： A device for delivering an agent comprises a housing (106) defining an enclosure (104). The housing (106) is configured to store an agent. The device further comprises an inlet (112), in fluid communication with the enclosure (104), for receiving a flow of pressurized fluid; an outlet (114) in fluid communication with the enclosure (104); and a filter (120) disposed within the enclosure (104). Pores of a wall of the filter (120) are configured such that the fluid is permitted to pass through the pores into a channel (122) defined by an inner surface of the wall. An actuation member is configured to transition between a first configuration, in which portions of the agent disposed proximally to the actuation member are prevented from passing distally of the actuation member, and a second configuration, in which portions of the agent disposed proximally of the actuation member are capable of passing distally of the actuation member.

摘要： A closure device includes a first ring structure having a first distal portion and a first medial portion and a second ring structure having a second distal portion and a second medial portion. The first and second distal portions are movable between an open position, where the first and second distal portions form an angle relative to one another for receiving target tissue therebetween, and a closed position, where the first and second distal portions are drawn toward one another for gripping the target tissue. The device also includes an anvil about which the first and second medial portions are formed. Either one of proximal motion of the anvil relative to the first and second rings or proximal motion of the medial portions relative to the anvil causes the first and second distal portions to move into either one of the open position or the closed position.

摘要： A medical device may comprise a handle portion; an insertion portion having a proximal end portion at the handle portion, wherein the insertion portion includes a Iumen therein and a distal end having a distal opening in communication with the lumen; and a member disposed within the lumen, the member having a distal end portion with an imaging device. The member may be configured to transition between a first configuration and a second configuration, in the first configuration, the imaging device may face distally, and, in the second configuration, the imaging device may face proximally. Extending the distal end portion of the member distally past the distal opening may cause the member to transition from the first configuration to the second configuration.

摘要： A device for treating a tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, clip arms, proximal ends of which are slidably received within the channel of the capsule so that the clip arms are movable between an open configuration, in which distal ends of the clip arms extend distally past the distal end of the capsule to be separated from one another, and a closed configuration, in which the clip arms are restrained via an interior surface of the capsule so that distal ends of the clips arms are drawn toward one another, and a reinforcement element coupled to the clip arms, the reinforcement element preventing deflection of the clip arms when engaging a target tissue.
