Abstract
A device and method of making a peel-away introducer sheath adapted for use in transcutaneous insertions of medical instrumentation according to an embodiment of the present invention includes, forming at least two anchor apertures in an end portion of a peel-away sheath tube, molding a fitting around the end portion by passing molten resin into a fitting mold and through the at least two anchor apertures, and cooling the resin within the mold and the at least two anchor apertures to thereby fasten the fitting to the sheath tube.
Claims16
A method of manufacturing a peel-away introducer sheath adapted for use in the transcutaneous insertion of medical instrumentation, said method comprising the steps of:
- forming at least two anchor apertures in an end portion of a peel-away sheath tube;
- molding a fitting around the end portion by passing a molten resin into a fitting mold, passing the molten resin around an exterior of the sheath tube, passing the molten resin into an interior space within the sheath tube, and passing molten resin through the at least two anchor apertures with the resin flowing between the exterior and the interior space through the apertures;
- and
- cooling the resin within the mold and the at least two anchor apertures to thereby fasten the fitting to the sheath tube.
A method for making a tear-away introducer having a sheath tube splitable along at least one longitudinal axis of the tube and a fitting in a contiguous mechanical connection with the sheath, the method comprising the steps of:
- forming at least two anchor apertures in an end portion of a peel-away sheath tube;
- inserting an inner mold portion into the end portion of the sheath, the mold portion having at least two channels defining respective flow paths;
- aligning the channels of the inner mold portion with the anchor apertures of the sheath whereby each of the flow paths are in fluid communication with an aperture;
- forming an outer mold portion around the inner mold portion inserted into the end portion of the sheath tube;
- passing molten resin into the outer mold portion whereby molten resin flows through the flow paths an the respective anchor aperture;
- and
- cooling the resin within the outer mold portion and the at least two anchor apertures to thereby fasten the fitting to the sheath tube in a contiguous mechanical connection.
