Abstract
A retrieval catheter 1 comprises a distal tubular sheath 2 with a reception space 5 into which an embolic protection filter 10 may be retrieved. An elongate connector 10 extends proximally from the sheath 2 to allow a clinician to control movement of the sheath 12. The sheath 2 is backloaded over a procedural catheter such as a balloon catheter 20, for example for post dilitation of a stent 55. The procedure is more efficient and procedure time is reduced because a catheter system is provided which allows a procedural step to be carried out and a filter 50 to be retrieved.
Claims45
A method for carrying out an interventional procedure at a treatment location in a vasculature comprising the steps of:
- deploying an embolic protection device distal of a treatment location in a vasculature;
- providing a procedural catheter for carrying out a procedure at a treatment site in the vasculature, the procedural catheter having a proximal end and a distal end;
- providing an embolic protection device retrieval catheter having a distal end defining a reception space for an embolic protection device and a proximal end;
- loading the proximal end of the retrieval catheter over the distal end of the procedural catheter;
- advancing the procedural catheter to the treatment location;
- advancing the retrieval catheter over the procedural catheter to present the distal end of the retrieval catheter to the deployed embolic protection device;
- retrieving the embolic protection device into the retrieval catheter;
- and
- removing the retrieval catheter and with it the embolic protection device from the vasculature.
An interventional catheter system comprising:
- a procedural catheter for carrying out a procedure at a treatment site in the vasculature, the procedural catheter having a distal end and a proximal end;
- and
- an embolic protection device retrieval catheter having a distal end defining a reception space for an embolic protection device and a proximal end, the proximal end of the retrieval catheter being adapted for loading over the procedural catheter.
A catheter having a reception space for receiving a medical device, the catheter being expandable around the reception space for ease of movement of a medical device relative to the reception space.
A transportation device comprising a reception portion having a reception space for receiving a medical device, and a control tether extending proximally of the reception portion to facilitate control of the position of the reception portion.
