Delivery system for a vascular device with articulation region
First Claim
1. Apparatus for deploying and retrieving a vascular device disposed on an elongated member from within a lumen of a delivery sheath, the apparatus comprising:
- a handle having a collet for selectively grasping and releasing the elongated member;
and a lumen flushing section coupled to the handle to allow translation and rotation therebetween, the lumen flushing section having a side port in fluid communication with the lumen of the delivery sheath and configured to allow the elongated member to pass therethrough to the handle.

Abstract
Apparatus and methods are provided for use in deploying and retrieving a vascular device suited for filtering emboli from a vessel and performing thrombectomy and embolectomy. The vascular device comprises a support hoop having an articulation region connected near a distal end of a guide wire, and a blood permeable sac affixed to the support hoop so that the support hoop forms a mouth of the blood permeable sac. A specialized delivery system allows precise control over deployment and retrieval of the vascular device, and the introduction or withdrawal of fluids from an operative site.

-
3. The apparatus of claim 2, wherein the apparatus has a delivery state, wherein the handle is translated longitudinally to a proximal-most position relative to the lumen flushing section, and the support hoop is retracted within the delivery sheath, and a deployed state wherein the handle is translated longitudinally to a distal-most position adjacent the lumen flushing section, wherein the support hoop extends beyond a distal end of the delivery sheath and engages an interior wall of a patient'"'"'s vessel.
-
4. The apparatus of claim 3, wherein the support hoop folds at the articulation region when the vascular device is contracted to the delivery state.
-
5. The apparatus of claim 3, wherein the mouth of the blood permeable sac is closed when the apparatus is in the delivery state.
-
6. The apparatus of claim 5 wherein opposite sides of the support hoop close towards one another when the apparatus is contracted to its delivery state.
-
7. The apparatus of claim 1 wherein the elongated member serves as a guide wire.
-
8. A method of deploying and retrieving a vascular device suitable for trapping emboli or thrombus during a medical procedure, the method comprising:
-
providing apparatus comprising a vascular device disposed on an elongated member within a lumen of a delivery sheath, a fluid port section coupled to the delivery sheath, and a handle coupled to the fluid port section for relative translation and rotation;
positioning the elongated member through the fluid port section;
engaging the elongated member to the handle so that motion of the handle is transmitted to the elongated member; and
advancing the delivery sheath to a desired location within a patient'"'"'s vessel. - View Dependent Claims (9, 10, 11, 12, 13)
translating the fluid port section proximally relative to the handle to withdraw the delivery sheath from a distal region of the elongated member;
expanding the vascular device to a deployed state within the patient'"'"'s vessel;
performing the medical procedure, the vascular device trapping emboli or thrombus;
translating the handle proximally relative to the fluid port section to retract the vascular device to a contracted state within the lumen of the delivery sheath; and
removing the vascular device and delivery sheath from the patient'"'"'s vessel.
-
-
10. The method of claim 9 further comprising flushing the lumen of the delivery sheath with saline injected through a side port of the fluid port section.
-
11. The method of claim 10 further comprising drawing suction through the side port to remove blood from an operative site at a distal end of the delivery sheath.
-
12. The method of claim 10 further comprising delivering medicaments through the side port to an operative site at a distal end of the delivery sheath.
-
13. The method of claim 8, wherein advancing the delivery catheter to a desired location within a patient'"'"'s vessel further comprises rotating the handle with respect to the fluid port section to position a distal end of the elongated member within a desired branch of a bifurcated vessel.
-
14. Apparatus for deploying and retrieving a vascular device disposed on an elongated member from within a lumen of a delivery sheath, the apparatus comprising:
-
a handle configured to selectively grasp and release the elongated member; and
a fluid port section coupled to the handle to allow translation and rotation therebetween, the fluid port section having a side port in fluid communication with the lumen of the delivery sheath and configured to allow the elongated member to pass therethrough to the handle. - View Dependent Claims (15, 16, 17, 18, 19, 20)
a support hoop attached to a distal region of the elongated member, the support hoop having an articulation region interposed between curved regions, and a blood permeable sac affixed to the support hoop so that the support hoop forms a mouth of the blood permeable sac.

-
16. The apparatus of claim 15, wherein the apparatus has a delivery state, wherein the handle is translated longitudinally to a proximal-most position relative to the fluid port section, and the support hoop is retracted within the delivery sheath, and a deployed state wherein the handle is translated longitudinally to a distal-most position adjacent the fluid port section, wherein the support hoop extends beyond a distal end of the delivery sheath and engages an interior wall of a patient'"'"'s vessel.
-
17. The apparatus of claim 16, wherein the support hoop folds at the articulation region when the vascular device is contracted to the delivery state.
-
18. The apparatus of claim 16, wherein the mouth of the blood permeable sac is closed when the apparatus is in the delivery state.
-
19. The apparatus of claim 18 wherein opposite sides of the support hoop close towards one another when the apparatus is contracted to its delivery state.
-
20. The apparatus of claim 14 wherein the elongated member serves as a guide wire.
