Catheter Device for Odour-Reducing Delivery and/or Discharge of Substances to/from the Human or Animal Body

A catheter device for delivery or discharge of substances, comprising:

• a balloon component configured to anchor and retain the catheter device in a body cavity;
• and
• a tube coupled to the balloon component,
• wherein the tube has an intracorporeal segment and an extracorporeal segment,
• wherein the balloon component extends around the intracorporeal segment,
• wherein at least the extracorporeal segment is formed from a multilayer film,
• wherein the multilayer film comprises at least one barrier layer made of an odor-inhibiting barrier material and at least one carrier layer configured to provide structural integrity to the multilayer film, and
• wherein a wall thickness of the carrier layer is greater than a wall thickness of the barrier layer.

A catheter device for delivery or discharge of substances, comprising:

• a balloon component configured to anchor and retain the catheter device in a body cavity;
• and
• a tube connected to the balloon component, the tube having an intracorporeal segment and an extracorporeal segment,
• wherein the balloon component extends around the intracorporeal segment,
• wherein at least the extracorporeal segment is formed from a multilayer film, the multilayer film comprising:
• (i) an outer layer comprising polyurethane, (ii) an inner layer comprising polyurethane, and (iii) a barrier layer comprising ethylene-vinyl alcohol copolymer (EVOH) between the outer layer and the inner layer, and
• wherein the extracorporeal segment is configured to elastically deform in response to an externally applied force and to spontaneously return to a starting shape when the externally applied force is reduced.

A method of delivering or discharging substances from a body cavity, comprising:

• anchoring a catheter device in the body cavity using a balloon component;
• and
• after anchoring the catheter device in the body cavity using the balloon component, passing substances from the body cavity through a tube coupled to the balloon component,
• wherein the tube comprises an intracorporeal segment and an extracorporeal segment,
• wherein the balloon component extends around the intracorporeal segment,
• wherein at least the extracorporeal segment is formed from a multilayer film,
• wherein the multilayer film comprises at least one barrier layer made of an odor-inhibiting barrier material and at least one carrier layer configured to provide structural integrity to the multilayer film, and
• wherein a wall thickness of the carrier layer is greater than a wall thickness of the barrier layer.
