Patent Images
1. An occlusive component delivery system comprising:
- at least one occlusive filamentary component comprising at least a polymeric gel; and
a delivery component having an engager comprising a separation region adapted to isolate and to allow dissolution or phase change of an intermediate portion of the occlusive filamentary component and release a distal portion of that occlusive filamentary component.

Abstract
A delivery system for placement of implantable occlusive devices allows placement of the devices place at selected treatment sites in the vascular system. Occlusive filaments produced from gel polymers are delivered by apparatus comprising various grippers, engagers, and couplers that are capable of holding onto the often slippery occlusive devices and of releasing and selectively severing them at desired treatment sites within the human body.

7. An occlusive component delivery system comprising:
-
at least one occlusive filamentary component comprising at least a polymeric gel, wherein the occlusive filamentary component has a shank with a substantially constant diameter and a distally located filament interference member; and
a delivery component having an engager, wherein the engager comprises an outer tubing member having an interior, female, distally located interference member with a passageway, the passageway having a size sufficient to allow the shank of the occlusive filamentary shape to freely slide therethrough but not the filament interference member, but the passageway allowing the passage of the filament interference member under a selected hydraulic pressure. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. An occlusive component delivery system comprising:
-
at least one occlusive filamentary component comprising at least a polymeric gel, wherein the occlusive filamentary component has a diameter; and
a delivery component having an engager, wherein the engager comprises a tubing member having an interior lumen sized to fit over and to grasp the occlusive filamentary shape but to allow passage of the occlusive filamentary shape upon application of a selected hydraulic pressure.
-
- 16. The system of claim 16, wherein the distal end of the engager comprises an interior lumen having an inner diameter larger than an adjacent diameter.
-
18. An occlusive component delivery system comprising:
-
at least one occlusive filamentary component comprising at least a polymeric gel; and
a delivery component having an engager, wherein the delivery component comprises an outer tubing member with a lumen having an open distal end and the engager comprises a proximally located pusher member and a distally located interwoven self-expanding tubular member adapted to grasp the occlusive filamentary shape when the self-expanding tubular member is situated within the outer tubing member lumen and to self-expand when the self-expanding tubular member is pushed outside the outer tubing member lumen by the pusher.
-
- 19. The system of claim 19, wherein the interwoven self-expanding tubular member comprises a metal or alloy.
-
22. An occlusive component delivery system comprising:
-
at least one occlusive filamentary component comprising at least a polymeric gel; and
a delivery component having an engager, wherein the delivery component comprises a tubing member with a lumen having a distal end and the occlusive filamentary component is situated within the tubing member lumen and is adapted to be pushed outside of tubing member lumen by application of hydraulic pressure to a proximal end of the tubing member. - View Dependent Claims (23)

24. An occlusive component delivery system comprising:
-
at least one occlusive filamentary component comprising at least a polymeric gel; and
a delivery component having an engager and a delivery lumen, wherein the engager comprises an expandable member disposed to compress and break the occlusive filamentary component when said occlusive filamentary component is present in the delivery lumen. - View Dependent Claims (25, 26)
