Abstract
A method for joining at least a first and a second component of a catheter using a clamping tool and heat treatment, without the use of heat shrink tubing. A device for joining at least two catheter components of a catheter includes or consists of: a clamping tool, a heating device, and optionally a cooling device. A (heat shrink tubing-free) catheter or catheter part, preferably a guide wire exit port, can be obtained by joining of at least two catheter components of the catheter by using the device or and/or the method.
Claims23
A method for joining at least two catheter components of a catheter, comprising:
- providing a clamping tool comprising a housing, at least one clamping element and an elastic component, wherein the at least one clamping element and the elastic component are configured to be arranged within the housing, wherein the at least one clamping element comprises a clamping element opening or recess configured to arrange the at least two catheter components therein and the elastic component comprises an elastic component opening or recess configured to arrange the at least two catheter components therein, and wherein the elastic component comprises ferromagnetic particles,
- arranging at least one electrical and/or thermal conductor in an internal space or in a lumen of at least one of the at least two catheter components,
- arranging the at least two catheter components within the clamping element opening or recess and within the elastic component opening or recess,
- pressing the at least one clamping element against the elastic component thereby applying a joining pressure to at least one of the at least two catheter components,
- subsequently or simultaneously heating the at least two catheter components while applying the joining pressure to at least one of the at least two catheter components to obtain joined components, and
- removing the joined components from the clamping tool.
