Abstract: An occluding device for occluding fluid flow through a lumen of a body vessel. The device comprises a coil and fibers attached to the coil. The coil has about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed. The fibers extend from the coil at a length.

Abstract: The two-piece percutaneous introducer sheath includes a distal portion which can remain in a blood vessel while a proximal portion can be removed after a valve at the proximal end of the distal portion is closed thus preventing undue loss of blood. Thus, a thrombus that has been pulled into the proximal portion can be removed when the proximal portion is removed without any significant blood loss after the sheath valve has been closed. Further, for any other useful therapeutic purpose, the proximal portion can be changed while the distal portion with its valve closed can remain in place in the vessel.

Abstract: A therapeutic medical procedure utilizing a miniature balloon catheter of the type including a resilient cannula adapted for attachment to a source of fluid in having a small outer diameter for insertion into small vessels containing fluid and an inflatable balloon having a mouth at the proximal end thereof. The balloon is attachably mounted on the end of the cannula in fluid communication therewith and the balloon is designed to seal when the cannula is attached therefrom. The medical technique includes inserting the balloon catheter into a small vessel and permitting the catheter to advance to a desired location in the vessel. The balloon catheter is attached to a source of fluid having an osmolarity substantially the same as the fluid in the vessel and the balloon is inflated to the volume limits of the balloon with fluid from the fluid source through the cannula until the balloon is fixed in position in the vessel. The cannula is then detached from the balloon and removed from the vessel.
