The present invention relates to a medical device for placement at a predetermined location within a vessel of the human body, and more particularly, relates to a collapsible aneurysm embolization device that is delivered through the lumen of a catheter and exits the catheter at a predetermined position within the vessel to thereby embolize a blood vessel defect, such as an aneurysm.

Endovascular aneurysm embolization device

A dilation catheter suitable for use in medical procedures is provided which includes a balloon disposed on an elongated flexible tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between a collapsed and expanded condition. The catheter includes a brace fitted over the balloon for restricting expansion of a selected portion of the balloon for forming a perfusion channel that allows fluid to be perfused past the balloon when it is expanded in a body vessel. A medical procedure for dilation under perfusion conditions is also provided.

Perfusion balloon brace and method of use

A flow directed catheter for use in medical diagnostic or therapeutic procedures having a strain relief segment between the relatively stiff proximal section of the catheter and the floppy distal tip portion in which the strain relief segment is formed of a polymeric material containing a radiopaque agent.

Flow directed catheter having radiopaque strain relief segment

A medical device for placing an embolic coil at a preselected location within a vessel comprising a positioning catheter having a distal tip for retaining the embolic coil which when pressurized with a fluid expands outwardly to release the coil at the preselected position. The positioning catheter includes a coaxial stiffening tube and helically wound coil transition zone to provide improved positioning of the embolic coil.

Embolic coil hydraulic deployment system having improved catheter

The stent delivery method and apparatus uses an elongate sheath having a rounded or tapered distal end portion which has a central opening and which is constructed in a manner that permits the distal end portion to expand easily. The method comprises the steps of: placing a stent on a balloon catheter or a balloon on a balloon guidewire thereby forming a stent on a balloon assembly; placing the stent on a balloon assembly in the elongate sheath having an elongate axis; pushing the sheath and stent on a balloon assembly to a desired site in the lumen of a vessel; positioning the stent on a balloon assembly at the desired site; withdrawing the sheath from the stent on a balloon assembly causing the distal end portion of the sheath to expand to pass over the stent and leaving the stent and balloon at the desired site in the lumen; expanding the balloon and stent to expand the stent to a desired diameter; collapsing the balloon; and, removing the balloon and the sheath from the lumen. The central opening permits a guidewire tip to extend therethrough.

Stent delivery method and apparatus

A dilation catheter suitable for use in medical procedures is provided. The catheter includes a balloon disposed on an elongated tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between an inflated expanded condition and a deflated collapsed condition. The balloon includes a longitudinally extending spiral wall which forms a longitudinally extending spiral channel spaced inwardly from the exterior surface of the balloon when the balloon is in its expanded condition to allow fluid to be perfused past the balloon.
