Apparatus and methods for forming dilatation balloons and catheters including same are provided. The balloons are fabricated of a material such as a nylon or a polyamide material, and they have been inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilation or the like up to a maximum pre-bursting pressure application. The maximum pre-bursting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-bursting sizes. The apparatus and methods facilitate fabrication of the balloons which are subjected to longitudinal elongation and radial expansion.

Method for manufacturing balloons for medical devices

A balloon catheter with an unreinforced stem collapses compactly. A method of introducing a balloon catheter into the body passage of a patient consists of loading the balloon end of the catheter into the unattached sheath of an endoscope and passing the elongated tubular leg attached to the balloon through the lumen of a working channel of an unattached bridge of an endoscope; then joining the bridge and the sheath to form a unitary endoscope and introducing the balloon into the body passage of a patient. A kit is disclosed which includes a balloon catheter and a separate adapter which can be used to introduce inflating fluid into the balloon.

Apparatus and methods for forming dilatation balloons and catheters including same are provided. The balloons are fabricated of a biaxially orientable material such as a nylon or a polyamide material, and they have an inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatation or the like up to a maximum pre-busting pressure application. The maximum pre-busting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-busting sizes. The apparatus and methods facilitate fabrication of the balloons which are subjected to longitudinal elongation or axial orientation and biaxial or radial orientation.

Stretch-blow molding method for manufacturing balloons for medical

In a catheter which comprises a tubular body having a bore, a wire member is loosely positioned in the bore. The wire member is secured to the catheter at a position adjacent the distal end, such position being radially spaced from the axis of the catheter. The wire member extends through the bore and out of the proximal end of the catheter, so that the distal end of the catheter can be bent by pulling the wire member. The wire member may also be connected at the distal end of the catheter to an electrode, so that the wire member serves both as a bending control member and as the means for electrical connection with the electrode.
