RU2024119929A - BLADDER CATHETER FOR INTRAVESICAL THERAPY DEVICES - Google Patents

Claims (30)

1. An insertion device assembly for deploying an intravesical therapy device into the bladder of a patient, comprising: a placement catheter defining a lumen, the lumen extending from the proximal end of the catheter to the outlet; a receiving funnel attached to the catheter for placement at the proximal end of the catheter; a probe removably inserted through a receiving funnel in the lumen of a placement catheter, wherein the probe comprises (i) a probe body extending between a proximal end of the probe and a distal end of the probe, wherein the probe body has dimensions allowing the intravesical therapy device to be passed through the lumen and the outlet into the bladder, and (ii) a blade attached to the probe body around the proximal end of the probe, wherein the blade is configured to engage with the receiving funnel. 2. An insertion device assembly according to claim 1, wherein the blade is formed by injection molding around the probe body at the proximal end of the probe or is formed integrally with the probe body. 3. An insertion device assembly according to claim 1 or 2, wherein the blade defines a curved thumb rest at the proximal end and optionally further defines a curved finger rest opposite the curved thumb rest. 4. An input device assembly according to any one of claims 1 to 3, wherein the blade comprises a gripping surface. 5. An inlet assembly according to any one of claims, wherein the blade is sized to allow for receipt into a receiving hopper. 6. An insertion device assembly according to any one of claims 1-5, wherein the blade comprises a nozzle configured to interlock with a receiving funnel for removably attaching the probe to the catheter for placement. 7. An assembled inlet device according to item 6, in which the branch pipe is designed to engage with the inner surface of the receiving funnel. 8. An assembled inlet device according to claim 6 or 7, wherein one or both of the branch pipe and the receiving funnel comprises at least one clamp adapted to be attached to the other of the branch pipe and the receiving funnel. 9. An inlet assembly according to any one of paragraphs 6-8, wherein the nozzle defines an annular ridge, and wherein the receiving funnel defines an annular channel having dimensions to ensure the possibility of mating with the annular ridge. 10. An assembled input device according to any one of paragraphs 6-9, in which the nozzle is designed with the possibility of generating acoustic and/or tactile feedback during engagement with the receiving funnel. 11. An insertion device assembly according to any one of claims 1 to 10, wherein the receiving funnel is formed by injection molding around the proximal end of the catheter or is integrally formed with the catheter for placement on the proximal end of the catheter. 12. An assembled inlet device according to any one of claims 1-11, wherein the receiving funnel has one or both of an oval profile and an oval perimeter. 13. An assembled input device according to any one of claims 1-12, wherein the receiving funnel extends asymmetrically in a direction transverse to the probe body. 14. An assembly for introducing the device according to any one of claims 1-13, in which the receiving funnel defines a lumen of the funnel, adapted to transfer a lubricant from the receiving funnel into the lumen of the catheter for placement, and optionally the receiving funnel is sized to ensure the possibility of receiving at least 1 ml of the lubricant. 15. The insertion device assembly of claim 14, wherein the receiving funnel is shaped to facilitate transfer of the lubricant from the bag into the lumen of the catheter for placement. 16. An assembled input device according to any one of paragraphs 1-15, in which the probe body has a continuous cross-section along the entire probe body. 17. An insertion device assembly according to any one of claims 1-16, wherein the placement catheter is transparent or translucent to visually determine the position of the intravesical therapy device or probe within the lumen. 18. An insertion device assembly according to any one of claims 1-17, wherein the distal end of the placement catheter comprises (i) a rounded atraumatic tip and/or (ii) a coude bend that is optionally aligned with the major axis of the withdrawal funnel such that the orientation of the withdrawal funnel indicates the orientation of the coude bend. 19. An insertion device assembly according to any one of claims 1-18, wherein the placement catheter comprises depth markings indicating the insertion depth and the orientation of the outlet. 20. An insertion device assembly according to any one of claims 1-19, wherein the placement catheter has (i) a length of 10 cm to 40 cm and/or (ii) an outer diameter of 5 Fr (outer diameter 1.67 mm) to 30 Fr (outer diameter 10 mm). 21. An insertion device assembly according to any one of claims 1-20, wherein one or both of the placement catheter and the probe comprises a radio tag. 22. An insertion device assembly according to any one of claims 1 to 21, wherein one or more of the placement catheter, blade, receiving funnel and probe are made of the same or different polymeric materials. 23. An input device assembly according to any one of paragraphs 1-22, in which the blade comprises: a central portion of the body surrounding the proximal end of the probe; a thumb rest defined at the proximal end of the blade; and a pair of side portions extending laterally from the central portion of the body between the thumb rest and the distal end of the blade. 24. An input device assembly according to claim 23, wherein the thumb rest has a concave surface facing away from the central body, an oval-shaped periphery, or both a concave surface facing away from the central body and an oval-shaped periphery. 25. A kit of parts comprising an insertion device assembly according to any one of claims 1-24; and an intravesical therapy device suitable for insertion into a patient's bladder using the insertion device assembly.
