A catheter according to the present invention includes a multiple lumen catheter for delivery of a liquid embolic composition through a first lumen and delivery of a solidification agent through a second lumen. The catheter allows adjustment of the relative longitudinal position of the two lumens to control the solidification of the embolic composition within a blood vessel. The multiple lumen catheter system is used by inserting the catheter endovascularly into an aneurysm site and injecting a liquid embolic composition through the first lumen while injecting a solidification agent through the second lumen to wash the area of the aneurysm of blood which has become saturated with solvent, while replacing it with a fresh solidification agent. The controlled solidification of the liquid embolic composition by use of the solidification agent allows the aneurysm to be filled precisely and rapidly even when the aneurysm is located such that gravity does not cause the liquid embolic composition to flow into the aneurysm.

Thrombectomy methods and apparatus for removing a thrombus from a blood vessel involving high velocity injection of a thrombolytic agent, e. g. , a plasminogen activator, through multiple, closely spaced, side wall infusion holes in a high strength catheter distal end infusion segment to lyse the adjacent thrombin. The infusion catheter is formed with a catheter lumen extending from a proximal end connector assembly to a distal end valve that is normally closed but is penetrable to allow introduction of a guidewire through the catheter lumen and distal end valve and to thereby allow advancement of the infusion catheter over the guidewire, thereby allowing access of the distal infusion segment to a wide number of locations. The infusion holes extend from the catheter lumen through the catheter side wall. Thrombolytic agent is pumped in a pulsatile manner through the catheter lumen under high pressure after removal of the guidewire and closure of the distal end valve.

Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

A temporary vascular filter system comprising a catheter and an elongate filter slideably carried near the distal end of said catheter. The vascular filter system can be inserted into a vessel percutaneously with the filter in a narrow-diameter “closed position” and expanded into a large diameter “open position” at the desired intravascular site. After deployment, the proximal portion of the catheter can be secured to the patient at the insertion site. While deployed, the filter component is capable of sliding along a portion of the catheter throughout a range of motion. The filter may have two filter meshes, which may have different degrees of porosity. The temporary vascular filter system can be left in the patient for hours or days and then collapsed into a withdrawal tube for removal from the patient.

An acute stroke recanalization system and processes include catheter-based improved reconstrainable or tethered neurological devices which are deliverable through highly constricted and tortuous vessels, crossing the zone associated with subject thrombi/emboli, where deployment impacts, addresses or bridges the embolus, compacting the same into luminal walls which enables perfusion and lysis of the embolus, while the improved neurological medical device itself remains contiguous with the delivery system acting as a filter, basket or stand alone stenting mechanism, depending on the status of the embolus and other therapeutic aspects of the treatment being offered for consideration.

Prosthetic nucleus apparatus and methods for treating an intervertebral disc are disclosed. Prosthetic nucleus apparatus may include a barrier sealant membrane and a prosthetic nucleus material. The barrier sealant membrane forms a chamber which can receive the prosthetic nucleus material. The barrier sealant membrane can be formed by depositing a layer of material on a tissue surface within a de-nucleated space within an intervertebral disc. The prosthetic nucleus material may be positioned within the chamber of the barrier sealant membrane after the barrier sealant membrane is deposited within the de-nucleated space. The barrier sealant membrane and the prosthetic nucleus material may be positioned within a patient through an axial trans-sacral bore. A plug may also be included to prevent expulsion of the barrier sealant membrane and prosthetic nucleus material.

Disclosed are methods for treating endoleaks arising from endovascular repair of abdominal aortic aneurysms. The disclosed methods involve the in situ sealing of endoleaks after placement of an endovascular prostheses in the abdominal aorta. Sealing of endoleaks is achieved by injection of either a biocompatible polymer or prepolymer fluid composition into the endoleak which composition in situ solidifies to seal the leak. Preferably, the biocompatible fluid composition comprises a contrast agent to allow the clinician to visualize the sealing process.
