摘要： A device for delivering pressurized fluid includes a handle having a lumen configured to receive a container of pressurized fluid, a cap to close the lumen and an indicator to move from a first position to a second position. The first position indicates disconnection of the container from a fluid path, and the second position indicates connection of the container to the fluid path.

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.

摘要： A device for treating tissue includes a capsule (112) having a channel (166) extending therethrough and clip arms (106) extending from a proximal end to a distal end. The proximal ends are received within the channel (166) and are movable between a tissue receiving configuration, in which the distal ends of the arms (106) are separated, and a tissue clipping configuration, in which the distal ends of the arms (106) are moved toward one another. The arms (106) include proximal and distal portions; the proximal portion includes longitudinal legs (126) extending from the proximal end to the distal portion. A plane of the legs (126) is rotated about a longitudinal axis of the arms (106) from a plane including the distal portion. The device also includes a yoke (110) having proximal and distal portions; the distal portion is releasably coupled to the legs (126) via a pin (138). The pin (138) is inserted through the distal portion.

摘要： 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.

摘要： A delivery device may comprise a sheath (10) configured to be inserted into a body lumen of a patient. The sheath may have a proximal end, a distal end, a first channel extending within the sheath from the proximal end to the distal end, and a second channel extending within the sheath from the proximal end to the distal end. A collective cross-sectional area of the first channel and the second channel may be more than 50% of a total cross sectional area of the sheath. The device may also be comprised of a handle (11) at the proximal end of the sheath, wherein the handle is configured to provide fluid communication between a first port and the first channel and a second port and the second channel.
