    Abstract: The present invention relates to a clipping system, comprising an proximal portion including a flexible shaft extending from a proximal end which, in an operative configuration, remains outside a living body to a distal end which, in the operative configuration, is inserted into the living body to a site adjacent to target tissue to be clipped, a clip releasably coupled to the proximal portion via a bushing at the distal end of the flexible shaft, the clip including a capsule including a channel extending therethrough, and a pair of clip arms, proximal ends of which are slidably received within the channel of the capsule to move the clip arms between an open configuration, in which distal ends thereof are separated from one another, and a closed configuration, in which the distal end of the clip arms are drawn toward one another, and a control member extending through the flexible shaft from a proximal end to a distal end releasably coupled to the proximal ends of the clip arms to move the clip arms between the open and the closed configurations, the distal end including a middle portion received between the proximal ends of the clip arms, a first portion of a pin and a second portion of the pin extending away from opposing surfaces of the middle portion to be received in openings extending through proximal ends of the clip arms to maintain an alignment of the clip arms relative to one another, the first and second portions being pulled proximally out of the openings of the clip arms and past a proximal edge thereof when a predetermined force is exerted on the clip arms via the distal end.

    Abstract: A clipping system comprises a catheter, a clip, a collet, and a control member. The catheter extends longitudinally from a proximal end to a distal end and includes a channel extending therethrough. The catheter includes a plurality of longitudinal slots extending through a wall thereof from the distal end along a distal portion of the catheter. The clip includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, and a pair of clip arms, proximal ends of which are slidably received within the channel of the capsule to move the clip arms between an open configuration and a closed configuration. The capsule of the clip is configured to be releasably received within the distal portion of the catheter. The collet is slidably mounted over the catheter and movable between an insertion configuration and a deployed configuration. In the insertion configuration, the collet is positioned over the distal portion of the catheter to press the distal portion against the capsule and to hold the capsule therein. In the deployed configuration, the collet is proximal the distal portion so that the clip is releasably from the distal portion of the catheter. The control member is connected to the clip arms and the collet via a yoke. The yoke includes a distal portion connected to the clip arms and a proximal portion connected to a portion of the collet. The distal and proximal portions of the yoke are connected to one another via a separable connection that is configured to separate when subject to a predetermined force exceeding a predetermined threshold value.

    IPC: A61B1/015

    Abstract: A valve stem for a medical valve may comprise a first lumen having a distal portion extending along a longitudinal axis of the valve stem; and a collapsible seal, wherein the collapsible seal forms an annular wall of the valve stem, and wherein the collapsible seal surrounds a part of the distal portion of the first lumen, wherein the medical valve has (a) a first configuration for delivering air to an air channel of a medical device, (b) a second configuration for delivering a fluid to a fluid channel of the medical device, and (c) a third configuration for delivering the fluid to the air channel the medical device, wherein, in the first configuration and the second configuration, the collapsible seal is in an expanded configuration, and wherein, in the third configuration, the collapsible seal is in a collapsed configuration.

    Abstract: The present invention relates to a device comprising: an elongate tubular body for use in a body lumen, the body lumen comprising a constriction portion that regulates flow between a first flow path and a second flow path; a stent having a proximal end and a distal end; a sleeve, coupled to the stent and formed of a flexible membrane, wherein the sleeve is configured to conform to a constricted configuration where flow through the sleeve is restricted and an expanded configuration where flow through the sleeve is enabled; wherein the stent is one of a plurality of stents including a proximal stent coupled to a proximal end of the sleeve and a distal stent coupled to the distal end of the sleeve; wherein the device includes a proximal flare formed by the proximal stent and coupled to a proximal end of the sleeve and a distal flare formed by the distal stent and coupled to a distal end of the sleeve, wherein the proximal flare is configured to affix to tissue of the body lumen in the first flow path and the distal flare is configured to affixto tissue of the body lumen in the second flow path, wherein the proximal flare and the distal flare differ in diameter; wherein the stent and the sleeve together provide a flow path through the elongate tubular body.
