Abstract
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.
Claims22
A connection device for attaching a catheter to an implantable port or pump, wherein the catheter is in fluid communication with said port or pump, comprising:
- a coupling device extending from said port or pump, comprising an arm portion and a stem, wherein the shape of the arm portion is substantially similar to an outer contour of said port or pump, and wherein the stem comprises a base portion and a tip portion;
- and
- a locking device slideable along a length of the catheter, comprising varying diameter portions that communicate directly with diameters of the base portion and tip portion of the stem, wherein a locking connection is established therebetween.
A connection device for attaching a catheter to an implantable port or pump, comprising:
- a coupling device extending from the implantable port or pump, comprising an arm portion and a stem, wherein the shape of the arm portion is substantially similar to an outer contour of the implantable port or pump, and wherein the stem comprises a base portion and a tip portion;
- and
- a locking device slideable over the catheter, comprising varying diameter portions that communicate directly with diameters of the base portion and tip portion, wherein a locking connection is established therebetween,
- wherein the base portion of the stem comprises a body portion and an engaging portion, wherein the engaging portion has a diameter that is greater than a diameter of the body portion, and wherein the tip portion of the stem comprises a barbed end, having a diameter larger than a lumen of the catheter.
A locking device for securing a catheter to a stem of an extension device, wherein the stem comprises a base portion and a tip portion, the base portion comprising a body portion and an engaging portion and the tip portion comprising a barbed end, comprising:
- a first diameter portion that is approximately equivalent to the diameter of said barbed end;
- a second diameter portion adjacent the first diameter portion that is approximately equivalent to the diameter of said tip portion;
- a third diameter portion adjacent the second diameter portion that is approximately equivalent to the diameter of said body portion;
- a fourth diameter portion adjacent the third diameter portion that is approximately equivalent to the largest diameter of the engaging portion;
- and
- a fifth diameter portion adjacent the fourth diameter portion having a diameter less than the diameter of the fourth diameter portion.
A coupling device for attachment of an implantable port or pump to a catheter, comprising:
- an arm portion having a proximal end that is fixedly attached to said port or pump and a distal end, said arm portion comprising a flexible material and shaped substantially similar to an outer contour of said implantable port or pump, said arm portion being biased to a resting position in close proximity to said port or pump, wherein said arm portion is movable to a connecting position away from said port or pump, and wherein said arm portion retracts to said resting position upon release from said connecting position;
- and
- a stem positioned at a distal end of said arm portion.
