AI Technical Summary

Technical Problem

Current surgical procedures for inserting bioactive compounds, such as dihydrotestosterone (DHT), near critical organs like the portal vein require multiple tools, increasing patient injury risk and complicating precise implantation, and there is a need for a tool that can deposit the compound without repeated insertions.

Method used

A laparoscopic implantation tool with a main shaft and auxiliary shaft, capable of delivering a DHT-containing implant to a targeted region, featuring a localizing system for precise placement and a dissection device to create a lodge, allowing single insertion and continuous localization.

Benefits of technology

The tool enables precise, single-insertion delivery of DHT near the portal vein, reducing patient injury risk, maintaining implant position, and ensuring sustained DHT release over years, with the implant being radio-opaque for easy localization and soft enough to avoid vascular damage.

Abstract

The invention concerns a laparoscopic implantation tool (100) comprising, along a main axis: - a casing (5) extending longitudinally along a main axis (AA), the casing (5) an inner channel extending across the casing along the main axis (AA) from an input (52) to an output, the casing (5) comprising a cavity formed along the inner channel (51), the cavity (10) being adapted for receiving a shuttle (9) containing an implant to be inserted in a subject; - a main shaft (6) comprising a proximal (61) end and a distal end (62); the main shaft (6) extending from the output (53) of the casing (5); - a auxiliary shaft configured to slide within the main shaft (6) when exercising a pushing to the auxiliary shaft the auxiliary shaft being configured, when moving along the main shaft, to first release the implant from the shuttle and to second moving the implant through the main shaft (6).
