Abstract
Embodiments disclosed herein include an embolization material. The embolication material includes a tubular strand, with an outer surface, having a distal end and a proximal end, wherein the outer surface defines one or more slits.
Claims20
A detacher for detaching embolization filler material having a flexible, annular, tubular configuration and an outer surface, with a proximal end and a distal end, comprising:
- a cannula, having an annulus, insertable into the proximal end of the embolization filler material annulus;
- a heat bond that bonds the cannula and embolization filler material to each other at the proximal end of the embolization filler material;
- a buttress tube positioned and slidable over the cannula and abutted against the surface of the embolization material;
- a rail wire positioned within the annulus of the cannula and advanced to the distal end of the embolization filler material;
- a locking knob attached to the buttress tube and engaging the cannula, wherein the cannula and buttress tube act as a pusher to move the embolization material through the delivery catheter into an embolization site.
An embolization material comprising:
- a tubular strand, with an outer surface, having a distal end and a proximal end, wherein the outer surface defines one or more slits, wherein the slits are oblique to the outer surface of the tubular strand.
An embolization material having a distal end and a proximal end, wherein the outer surface defines one or more slits.
A method for detaching tubular embolization filler material defining a lumen, from a catheter, comprising:
- bonding the tubular embolization filler material to a cannula;
- positioning a buttress tube, having a locking mechanism over the cannula so that when the buttress tube is moved distally, the buttress tube contacts the tubular embolization filler material;
- inserting a rail wire into the cannula and advancing the rail wire to a distal end of the embolization filler material;
- lock the buttress tube to the cannula and embolization filler material with the locking mechanism;
- advancing the buttress tube, cannula and embolization filler material to an aneurysm site with a delivery catheter;
- and
- unlock the locking mechanism, and move the cannula proximately while holding the buttress tube stationary until the embolization filler material is released into the aneurysm site.
