Interventional sinus endoscope
An apparatus and method are presented for a therapy delivery device including a catheter, an endoscope and an endoscope shaft, one or more attachment features for attaching the catheter to the endoscope, wherein the catheter has an expandable lumen at a distal end and wherein the expandable lumen expands upon injection of a therapy at the proximal end of the catheter. Attachment features may be a series of clips along the length of the catheter for attaching to an endoscope or a second lumen on the catheter wherein an endoscope may through one of said lumens. Targeted therapy delivery may be a hydrogel or a chitosan hydrogel to provide a treatment within a sinus of a patient.
1. An apparatus, comprising: a therapy delivery device, comprising:
a multi-lumen catheter comprising at least a first lumen and a second lumen, the first lumen surrounding the second lumen; and
an endoscope and an endoscope shaft,
wherein a distal end of the endoscope shaft is insertable through said second lumen of the multi-lumen catheter,
wherein the first lumen of the multi-lumen catheter is an expandable lumen at a distal end, and
wherein the distal end of the first lumen comprises a plurality of pores along a top surface, and selectively expands upon injection of a therapy such that the distal end of the first lumen expands more than a section of the first lumen extending towards the distal end of the first lumen,
wherein the section of the first lumen comprises a non-compliant polymer having a compliance range of 0-10%, and the distal end of the first lumen comprises a compliant polymer having a compliance range of 20-100%.
2. The apparatus of claim 1 , wherein the therapy includes at least one of a gel, a hydrogel, a fluid, a liquid, a dye and a contrast agent.
3. The apparatus of claim 2 , wherein the therapy is a chitosan based hydrogel.
4. The apparatus of claim 1 , wherein the multi-lumen is a bilumen.
