Stent and Catheter Systems for Treatment of Unstable Plaque and Cerebral Aneurysm

A kit for the treatment of an unstable plaque or an aneurysm at a desired location in a patient, the kit comprising:

• at least one guide catheter (GC) adapted for placement proximal to the desired location;
• at least one guide wire adapted for placement distal to the desired location;
• at least one microcatheter adapted for placement distal to the desired location over the guide wire;
• at least one resorbable stent (RS) assembly adapted for placement adjacent to the desired location and deployable through the at least one microcatheter each RS assembly having a RS adapted to stabilize the unstable plaque or aneurysm for a therapeutically effective time period and resorbable into the patient over a resorb time.

A co-axial stent system (COSS) comprising:

• a catheter system retaining:
• a collapsible resorbable stent (RS) having:
• a collapsible cylindrical body for compressed containment within the catheter system;
• and,
• resorption properties where the RS is resorbable within a patient over a resorb time;
• a collapsible metal stent (MS) affixed to a stent wire (SW) passing through the catheter system, the MS having:
• a collapsible cylindrical body for compressed containment within the catheter system and the RS;
• sufficient self-expansion properties enabling the MS to bias the RS against the arterial vessel upon deployment;
• wherein the MS may be unsheathed and re-sheathed from the catheter system and wherein upon deployment of the RS and re-sheathing of the MS, the RS remains deployed within an arterial vessel.

A co-axial stent system (COSS) comprising:

• a catheter system having an outer catheter, an inner catheter and a microwire having a proximal zone running external to the outer catheter and a distal zone entering the inner catheter through a distal slot in the outer catheter, the inner catheter having a distal inner zone retaining:
• a collapsible resorbable stent (RS) having:
• a collapsible cylindrical body for compressed containment within the distal inner zone of the inner catheter between the outer catheter and inner catheter;
• and,
• resorption properties where the RS is resorbable within a patient over a resorb time;
• a collapsible metal stent (MS) affixed to the distal inner zone between the outer catheter and the inner catheter, the MS having:
• a collapsible cylindrical body for compressed containment within the distal inner zone and within the RS;
• sufficient self-expansion properties enabling the MS to bias the RS against the arterial vessel upon deployment;
• wherein the MS may be unsheathed and re-sheathed from the catheter system and wherein upon deployment of the RS and re-sheathing of the MS, the RS remains deployed within an arterial vessel.
