System, device and method combining bioabsorbable foam with vacuum technology for neoplastic cysts

A catheter system comprising:

• a catheter, wherein the catheter comprises an elongated body having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, a sheath disposed about the elongated body, the sheath comprising a distal tip that extends distally beyond the distal end of the elongated body to form a chamber distally of the distal end of the elongated body;
• an absorbent material having a compressed configuration sized to fit within the chamber of the sheath and an expanded configuration larger than the compressed configuration, the absorbent material comprising a radiolucent material, an echogenic material, a drug eluting material, a bioabsorbable material, or a combination thereof;
• a handle coupled to a proximal end of the sheath, the handle comprising a release mechanism shaped and configured to release the absorbent material from the chamber;
• a vacuum passage configured to apply a proximal suction force through the lumen;
• and a push rod coupled to the release mechanism and extending through the lumen, wherein the push rod is configured to release the absorbent material from the chamber, and wherein the push rod forces the absorbent material from the chamber.

A device comprising:

• an absorbent material disposed within the chamber;
• a handle coupled to a proximal end of the sheath, the handle comprising a release mechanism configured and positioned to release the absorbent material from the chamber;
• a vacuum passage configured to apply a proximal suction force through the lumen and to the distal end of the sheath;
• and a push rod coupled to the release mechanism and extending through the lumen, wherein an entirety of the absorbent material is distal to the push rod.
