An apparatus for sealing and severing a web of film. The apparatus includes a first jaw located on one side of the web of film and a second jaw located on a second side of the web of film. The first and second jaws cooperate to grip the web of film. Located within the first jaw is a heater member for sealing and severing the web of film. The heater member is secured so that the time and/or pressure at which the heater member engages the web of film may be varied independent of the first jaw.

Apparatus for sealing and severing a web of film

An apparatus for sealing a web of film including a heater member for melting a portion of the film to create side and chevron seals. A back-up bar is located diametric the heater member. The heater member includes two elongated heater bars and two wing heater bars.

Apparatus for sealing a web of film

A method of making a curved-tip (coude) catheter which comprises: inserting an end of a flexible, thermoplastic tube into the bore of a closed-end, hollow, tubular die which defines the desired curve of the curved-tip catheter. The tubular die is heated to a temperature above the plastic melt temperature of the thermoplastic tube, while advancing the tube into the die, to cause at least about 0.5 cm. of the tube end to collapse into a generally solid, curved mass. The die and tube contained therein are then cooled to a temperature below the plastic melt temperature, and the tube is withdrawn having a closed, formed coude tip.

Apparatus for making coude catheters

A method of making a elbowed end (coude) catheter which comprises: inserting an end of a flexible, thermoplastic tube into the bore of a closed-end, hollow, tubular die which defines the desired curve of the elbowed end catheter. The tubular die is heated to a temperature above the plastic melt temperature of the thermoplastic tube, while advancing the tube into the die, to cause at least about 0.5 cm. of the tube end to collapse into a generally solid, curved mass. The die and tube contained therein are then cooled to a temperature below the plastic melt temperature, and the tube is withdrawn having a closed, formed coude tip.
