Abstract
Devices and methods may allow for the removal of material from a remote location in the vasculature. In an example of such a remote location, the device may be used in the vasculature of a lower extremity in combination with an external cuff. The external cuff may create a dam preventing material from flowing throughout the body. With the external cuff in place, the device of the present disclosure may be utilized to suction the material from the vasculature while rotating the catheter to assist in the removal of the material.
Claims18
A method of removing a material from a vasculature, the method comprising:
- inserting a catheter into the vasculature with a handheld device;
- locating a distal tip of the catheter at a location for treatment within the vasculature;
- placing an external cuff distal to the location for treatment to create a restricted flow;
- restricting flow within the vasculature distal to the location for treatment;
- linearly actuating a trigger of the handheld device to rotate the distal tip of the catheter;
- dislodging or destroying the material with the distal tip of the catheter at the location for treatment within the vasculature;
- and
- suctioning the material from the vasculature, through the catheter, into the handheld device.
A method for removing material from the vasculature, the method comprising:
- applying an external pressure cuff distal to a location for treatment;
- coupling a catheter to a distal end of a handheld device;
- inserting the catheter into the vasculature and locating a distal tip of the catheter at the location for treatment;
- actuating a valve of the handheld device to create a suction within a chamber of the handheld device;
- actuating a trigger of the handheld device to rotate the distal tip of the catheter;
- and
- suctioning material from the vasculature through a lumen of the catheter and into the chamber of the handheld device,
- wherein rotating the distal tip of the catheter assists in removal of the material from the vasculature, and
- wherein the chamber remains stationary during rotation of the distal tip of the catheter.
