A medical device clamping assembly (10) includes proximal and distal axially aligned members (60,12). The proximal and distal members (60,12) are movable relative to each other. A channel (22) is defined through the members (60,12) for receipt of at least a portion of a treatment device (34) therethrough. A clamping member (88) is configured between the proximal and distal members (60,12) and defines a portion of the channel (22). The clamping member (88) is actuated between an unclamped configuration and a clamped configuration by moving one of the distal or proximal members (12,60) relative to the other. In its clamped position, the clamping member (88) clamps upon and restricts axial movement of the treatment device (34) through the assembly (10); however, the assembling may move on or within the treatment device (34) and does not necessarily limit at least partial retraction of the device (34) from a patient but rather only restricts insertion of the device (34) beyond that point at which the assembly (10) contacts a stopper (20).

La présente invention se rapporte à un ensemble de retenue (10) pour dispositif médical, qui comprend des éléments proximal et distal (60, 12) alignés axialement. Les éléments proximal et distal (60, 12) peuvent se déplacer l'un par rapport à l'autre. Un canal (22) défini à travers les éléments (60, 12) est destiné à recevoir au moins une partie d'un dispositif de traitement (34). Un élément de retenue (88) disposé entre les éléments proximal et distal (60, 12) définit une partie du canal (22). L'élément de retenue (88) est actionné entre une configuration de non-retenue et une configuration de retenue, par le déplacement de l'un des éléments distal et proximal (12, 60) par rapport à l'autre. Dans sa position de retenue, l'élément de retenue (88) se fixe sur le dispositif de traitement (34) et restreint le mouvement axial de ce dernier à travers l'ensemble (10) ; toutefois, l'ensemble peut se déplacer sur le dispositif de traitement (34) ou à l'intérieur de ce dernier, et ne limite pas nécessairement la rétraction au moins partielle du dispositif (34) du corps d'un patient, mais restreint plutôt l'insertion du dispositif (34) au-delà du point où l'ensemble (10) entre en contact avec une butée (20).
