Abstract
Various aspects of the present disclosure are directed toward an embolic filter system. The embolic filter system generally includes a filter and an elongated element. In some examples, the elongate element extends to a position distal to a proximal end of the filter and operates to protect against medical devices entangling with the filter. In some examples, the elongate element is soft and compliant and operates with a hemostatic seal to provide for a hemostatic seal within a lumen of the elongate element while maintaining the lumen as a working lumen through which medical devices can be passed.
Claims11
An embolic filter comprising:
- an elongate element having a proximal end and a distal end, the elongate element including a first structural element and a first covering material, the elongate element having sufficient structural integrity to support being advanced within a delivery sheath;
- and
- a filter portion positioned such that the distal end of the elongate element extends beyond the filter portion, the filter portion including a second structural element and a second covering material, wherein a portion of the second covering material includes a plurality of perforations configured to filter embolic debris from blood flowing into the filter portion;
- wherein a distally directed force applied to the proximal end of the elongate element is operable to cause a distal translation of the elongate element and the filter portion to the delivery sheath.
An endoprosthesis delivery device comprising:
- an expandable filter element mounted on a catheter shaft, having a capture area within the expandable filter element when the expandable filter element is deployed;
- an elongated conduit configured such that a leading end of the elongated conduit extends through and beyond the expandable filter element when the expandable filter element is deployed at a treatment site, the elongated conduit configured to allow for delivery of an endoprosthesis beyond the expandable filter element;
- and
- wherein the elongated conduit includes at least one aperture through a side wall providing fluid communication between the capture area and an interior of the elongated conduit;
- wherein the elongated conduit and the catheter shaft form a single monolithic unit.
