Abstract
Apparatus and systems are disclosed that incorporate coupling mechanisms to enable coupling of two mating member such as medical devices such as introducers, sheaths, dilators. More specifically, the disclosure relates to releasable coupling mechanisms, to allow for releasable coupling of two medical devices such as a dilator and a sheath so the devices can be maneuvered and/or manipulated together for example during a part of a medical procedure.
Claims19
A releasable coupling mechanism comprising:
- a housing defining a primary mating member defining an opening for receiving a secondary mating member to be coupled thereto;
- and
- an elastically deformable retaining component comprises a resilient u-shaped cantilever terminating in a snap having a first ramp defining an insertion force and a second ramp defining a removal force, wherein the insertion force and the removal force are substantially equivalent, the elastically deformable retaining component being positioned within the housing, for releasably coupling the secondary mating member to the housing upon insertion thereof into the housing;
- wherein the elastically deformable retaining component has a first engaging configuration and a second non-engaging configuration, wherein the elastically deformable retaining component is moveable into its second non-engaging configuration upon insertion of the secondary mating member into the housing to enable the secondary mating member to advance into the housing and is moveable thereafter into its first engaging configuration to couple the secondary mating member to the primary mating member preventing the secondary mating member to be detachable therefrom, preventing disengagement thereof in the absence of force to prevent the secondary mating member to be removable from the opening thereof.

A releasable coupling mechanism comprising:
- a housing defining a primary mating member defining an opening for receiving a secondary mating member to be coupled thereto;
- and
- an elastically deformable retaining component comprises one or more resilient u-shaped cantilever terminating in a snap having a first ramp defining an insertion force and a second ramp defining a removal force, the elastically deformable retaining component being positioned within the housing, for releasably coupling the secondary mating member to the housing upon insertion thereof into the housing;
- wherein the elastically deformable retaining component has a first engaging configuration and a second non-engaging configuration, wherein the elastically deformable retaining component is moveable into its second non-engaging configuration upon insertion of the secondary mating member into the housing to enable the secondary mating member to advance into the housing and is moveable thereafter into its first engaging configuration to couple the secondary mating member to the primary mating member preventing the secondary mating member to be detachable therefrom, preventing disengagement thereof in the absence of force to prevent the secondary mating member to be removable from the opening.
