Containers and methods for delivering vaso-occluding filaments and particles
First Claim
1. A kit for holding vaso-occluding elements comprising:
- a plurality of hydratable vaso-occluding elements; and
a container adapted to hold the hydratable vaso-occluding elements, said container having an inlet port and an outlet port, wherein at least one of the fluid inlet and outlet ports is adapted for fluid connection with a fluid source.

Abstract
Containers for holding and delivering vaso-occluding materials, such as hydrogel particles and filaments include a fluid inlet port and a fluid outlet port that are respectively fluidly connectable with a fluid source and a delivery catheter. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping.

52. A container for holding hydratable vaso-occluding elements, said container comprising:
-
a delivery tube having an inlet end, a delivery end, a lumen extending from the inlet end to the delivery end, a length from inlet end to delivery end of at least 5 cm and a maximum lumen width along its length in the range from 0.4 mm to 5 mm; and
an inlet coupling disposed on the inlet end of the delivery tube, said inlet coupling being adapted to fluidly couple to a fluid source;
wherein the delivery tube is configured to reduce the length of the container. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)

71. A method for introducing vaso-occluding elements into an implanted catheter, said method comprising:
-
providing said elements in a hydration liquid in a delivery tube having a lumen with a length of at least 2 cm and a maximum width along its length in the range from 0.4 mm to 5 mm;
mating a delivery end of the tube with a hub of the implanted catheter; and
transferring said element(s) in the hydration liquid from the lumen and through the delivery end of the delivery tube into a lumen of the implanted catheter. - View Dependent Claims (72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90)

91. A system for delivering vaso-occluding elements, said system comprising:
-
at least one hydratable vaso-occluding element having a width when hydrated; and
a delivery tube having an inlet end, a delivery end, and a lumen extending from the inlet end to the delivery end;
wherein the lumen of the delivery tube is adapted to hold said hydratable vaso-occluding element and has a width along its length which is at least as large as the width of the vaso-occluding element and less than twice the width of the vaso-occluding element. - View Dependent Claims (92, 93)
-
- 94. A method for delivering hydratable vaso-occluding elements to a target body location, said method comprising singly dispensing one or more vaso-occluding elements through a delivery tube to a catheter lumen, wherein the lumen of the delivery tube is adapted to pass only a single vaso-occluding element at a time.
