Multi lumen IVC filter retrieval device

A multi lumen IVC filter retrieval device, comprising:

• a sheath having a first lumen that traverses an entire length of the sheath, said first lumen having a proximal portion and a distal portion, said first lumen containing a snare that can be deployed out a distal end of the sheath and retracted back into the distal portion of the first lumen;
• said sheath having a second lumen within the proximal portion of said first lumen, said second lumen opens through a sidewall of the sheath proximal of the distal end of the sheath so that said second lumen does not extend distal of said proximal portion of said first lumen into said distal portion thereof, wherein said second lumen occupies the proximal portion of said first lumen but does not occupy the distal portion of said first lumen;
• said second lumen contains an assist device that can be deployed through the sidewall of the sheath and used during an IVC filter retrieval procedure;
• and
• said distal portion of the first lumen provides a space unobstructed by said second lumen, thereby allowing a full inner diameter of said first lumen to contain a retrieved IVC filter and snare in the distal portion of the first lumen while still providing access for the assist device in the second lumen.
