Implantable pump connector for catheter attachment
View Patent ↗A catheter system for locking a catheter to an implantable pump and for effectively flushing a catheter after implantation within a body. A locking component comprises an extension boot and catheter lock that together fluidly connect the catheter to the pump in a secure, safe and effective manner. A catheter component comprises a design having kink-resistant walls and a unique tip. A flushing component comprises a hub and stylet combination characterized by a hydrophilic coating on the stylet and a flush through hub to allow flushing of the stylet while inside the catheter.
1. A coupling device for attachment of an implantable port or pump having a curved outer contour to a catheter, said coupling device comprising:
an arm portion having a proximal end that is rigidly attached to the port or pump and a distal end, said arm portion comprising a flexible material and extending away from the port or pump and curved throughout its length to correspond to the curved outer contour of the port or pump when said arm portion is in a resting position so as to reduce an overall space occupied by the port or pump, wherein said arm portion is movable to a connecting position away from the port or pump while said proximal end remains rigidly attached to the port or pump, and wherein said arm portion retracts toward the port or pump to said resting position upon release from said connecting position; and
a stem portion at said distal end of said arm portion, said stem portion aligned substantially coaxially with said arm portion.
2. The coupling device according to claim 1 , wherein an audible confirmation is provided upon attachment of the port or pump to the catheter.
3. The coupling device according to claim 1 , wherein a tactile confirmation is provided upon attachment of the port or pump to the catheter.
4. The coupling device according to claim 1 , wherein said stem portion comprises a rigid material.
5. The coupling device according to claim 1 , wherein said stem portion comprises one of stainless steel and titanium.
6. The coupling device according to claim 1 , wherein said flexible material comprises a polymer.
7. The coupling device according to claim 1 , wherein said stem portion comprises a base and a tip.
8. The coupling device according to claim 7 , wherein said base comprises an engaging lock portion for locking said stem portion to the catheter.
9. A coupling device for coupling an implantable device having a curved outer contour to a catheter, said coupling device comprising:
an arm portion having a proximal end rigidly coupled to the implantable device and a distal end, said arm portion comprising a flexible material and extending away from the port or pump and curved throughout a length of said arm portion to correspond to the curved outer contour of the implantable device when said arm portion is in a resting position, said distal end movable away from the implantable device to a connecting position while said proximal end remains rigidly attached to the implantable device and retractable toward the implantable device to the resting position upon release from the connecting position; and
a stem portion at said distal end of said arm portion, said stem portion aligned substantially coaxially with said arm portion.
10. The coupling device according to claim 9 , wherein said stem portion comprises a base and a tip.
11. The coupling device according to claim 9 , wherein said base comprises an engaging lock portion to facilitate locking said stem portion to the catheter.
12. A coupling device for coupling an implantable device to a catheter, the implantable device having a curved outer contour, said coupling device comprising:
an arm portion having a proximal end rigidly coupled to the implantable device and a distal end, said arm portion comprising a flexible material and biased to a resting position in close proximity to the implantable device, said arm portion extending away from the implantable device and curved along a length of said arm portion to correspond to the curved outer contour of the implantable device when said arm portion is in the resting position to reduce an overall space occupied by the implantable device, at least said distal end movable away from the implantable device to a connecting position while said proximal end remains rigidly attached to the implantable device and retractable toward the implantable device to the resting position upon release from the connecting position; and
a stem portion at said distal end of said arm portion, said stem portion aligned substantially coaxially with said arm portion.
13. The coupling device according to claim 1 , wherein said arm portion extends away from the port or pump and is curved throughout a length of said arm portion such that a space is defined between said arm portion and the port or pump.
