Abstract
A packaged closed intermittent urinary catheter system equipped with a dispensing system and method of dispensing a packaged catheter using the dispensing system. The dispensing system is a pair of separately translatable movement control devices, each operably engaging the catheter for permitting unidirectional movement of the catheter in a first axial direction relative to the movement control devices. The movement control devices may be mounted to a hand-grippable assembly with a sliding or pivoting movable member reciprocal to a base member. Alternatively, the movement control devices are mounted to a coupling member and a spring member biases them apart.
Core Innovation
The invention provides a closed intermittent urinary catheter system equipped with a catheter dispensing device. The system includes a sterile flexible plastic bag defining a closed reservoir with an outlet opening and a catheter retained within the reservoir, with the distal insertion tip positioned adjacent to and aimed toward the outlet opening.
A movable member is mounted within the reservoir over the catheter and includes a movable catheter control device that automatically permits distal movement of the catheter relative to the movable member and automatically resists proximal movement of the catheter relative to the movable member. A base member is mounted over the catheter distal insertion tip, fixed to the bag at the outlet opening, and configured to receive the movable member for reciprocal movement in a distal-proximal direction.
The base member contains a stationary catheter control device that automatically permits distal movement of the catheter relative to the base member and automatically resists proximal movement of the catheter relative to the base member. Reciprocal movement of the movable member relative to the base member causes the catheter to be advanced distally from the bag through the outlet opening, and the movable member may be displaced by manipulating it through the front side of the bag while holding the base member stationary, or by a friction-enhancing pad adhered to an exterior surface on the front side of the bag.
Claims Coverage
The partial content includes two independent claims (clm-00001 and clm-00011), each covering a closed intermittent urinary catheter system with a sterile flexible plastic bag reservoir and a catheter advancement mechanism using reciprocal motion combined with catheter control devices that automatically permit distal movement and resist proximal movement. The independent claims further distinguish how the movable member is manipulated and the use of a friction-enhancing pad.
Sterile flexible plastic bag reservoir with outlet opening and catheter retained therein
A sterile flexible plastic bag having front and rear sides and defining a closed reservoir with an outlet opening, with a catheter defining a longitudinal axis retained within the reservoir and having a distal insertion tip positioned adjacent to and aimed toward the outlet opening.
Reciprocal distal-proximal movement between movable member and base member to advance catheter distally
A base member within the reservoir configured to receive the movable member for reciprocal movement therein in a distal-proximal direction, the base member being mounted over the catheter distal insertion tip and fixed to the bag at the outlet opening, wherein reciprocal movement of the movable member relative to the base member causes the catheter to be advanced distally from the bag through the outlet opening.
Automatically permitting distal movement and resisting proximal movement using movable and stationary catheter control devices
A movable member within the reservoir mounted over the catheter and having a movable catheter control device therein that automatically permits distal movement of the catheter relative to the movable member and automatically resists proximal movement of the catheter relative to the movable member, and a stationary catheter control device in the base member that automatically permits distal movement of the catheter relative to the base member and automatically resists proximal movement of the catheter relative to the base member.
Movable member manipulation through the front side of the bag while holding base member stationary
The movable member may be displaced relative to the base member by manipulating the movable member through the front side of the bag while holding the base member stationary.
Friction-enhancing pad adhered to exterior surface for manipulating movable member
A friction-enhancing pad adhered to an exterior surface on the front side of the bag directly opposite the movable member, wherein the movable member may be displaced relative to the base member by manipulating the friction-enhancing pad.
Across the independent claims, the core claim coverage centers on a closed intermittent urinary catheter system in which a movable member and a base member undergo reciprocal distal-proximal movement while movable and stationary catheter control devices automatically permit distal catheter advancement and resist proximal movement. Claim differentiation includes direct manipulation through the front side of the bag versus manipulation via a friction-enhancing pad, and the base member relationship to the outlet opening.
