Abstract
A delivery catheter system includes a catheter and an integrated embolic filter that is deployable prior to the delivery of a prosthesis in a patient's vasculature and retrievable after delivery of said prosthesis. The embolic filter is moveable from a collapsed state, in which the embolic filter is retained within the catheter body, to a deployed state in which the embolic filter extends from the catheter body and, in use, into contact with an inner wall of a patient's vasculature.
Claims12
A delivery catheter system comprising:
- a catheter including an elongate catheter body having a distal tip and a capsule containing a deliverable prosthesis;
- an integrated embolic filter, the embolic filter deployable prior to the delivery of a prosthesis in a patient's vasculature and retrievable after delivery of said prosthesis;
- and
- a deflecting member connected to an internal surface of the catheter body and to a control member, wherein the control member is configured to manipulate the deflecting member so as to adjust the position of the distal tip within the vasculature of a patient, in use,
- wherein the embolic filter is moveable from a collapsed state, in which the embolic filter is retained within the catheter body, to a deployed state in which the embolic filter extends from the catheter body and, in use, into contact with an inner wall of a patient's vasculature.

- an integrated embolic filter, the embolic filter deployable prior to the delivery of a prosthesis in a patient's vasculature and retrievable after delivery of said prosthesis,
- wherein the embolic filter is moveable from a collapsed state, in which the embolic filter is retained within the catheter body, to a deployed state in which the embolic filter extends from the catheter body and, in use, into contact with an inner wall of a patient's vasculature,
- wherein the embolic filter is connected to a releasable fastener that is releasably engaged to the capsule so as to releasably attach the embolic filter to the capsule,
- wherein relative movement between the catheter body and the capsule in a first direction beyond a predetermined distance causes the releasable fastener to disengage from the capsule.
A delivery catheter system comprising;
- a catheter including an elongate catheter body having a distal tip and a capsule containing a deliverable prosthesis;
- and
- an integrated embolic filter, the embolic filter deployable prior to the delivery of a prosthesis in a patient's vasculature and retrievable after delivery of said prosthesis,
- wherein the embolic filter is moveable from a collapsed state, in which the embolic filter is retained within the catheter body, to a deployed state in which the embolic filter extends from the catheter body and, in use, into contact with an inner wall of a patient's vasculature,
- wherein the embolic filter is connected to a resilient fastener, and wherein said resilient fastener is urged into engagement with an external surface of the capsule in a first, retracted, position so as to releasably attach the embolic filter to the capsule,
- wherein the resilient fastener expands into an internal groove on the catheter body in a second, advanced, position such that the resilient fastener disengages from the capsule to enable the capsule to be advanced independently of the embolic filter.
