A purse suturing device for a hollow viscus, such as the oesophagus or rectum, is a specialised surgical stapler used to prepare tissue for an anastomosis (the joining of two body structures).

This device is particularly useful in areas where hand-sewn suturing is difficult or impossible, such as during laparoscopic or pelvic surgery.Key components and features of the device include:Circular Stapler: Comprises a tubular stapler head, a handle with an actuator, and an anvil.

Dual-Position System:Pursing Position: The anvil is retracted from the stapler head, creating space for a suturing thread to be wound around the viscus.Stapling Position: The anvil moves close to the stapler head, compressing and folding the tissue layers together.Suturing Thread: Typically a plastic monofilament like polypropylene, which is wound around the tissue and tightened against the anvil's pole to create a pursed fold.

Pushing Stick: An optional tool used to fasten the thread tightly around the pole without needing to tie a knot.Staple Carrier: Includes a series of projections and recesses that hold the staples and provide space for the pushing stick to operate.This device improves surgical outcomes by providing a more secure and better-vascularised edge for subsequent procedures compared to traditional linear staplers, which can sometimes leave portions of the suture outside the target area.

Efficient management of the selective collection of urban waste. Currently, more than 70% of the solid waste deposited in containers is either incinerated or ends up in landfills due to the lack of classification (e.g. paper, glass, plastics, and organic matter), which prevents its industrial reuse.

The CaliWASTE smart container aims to improve this classification, guaranteeing that only the waste destined for this specific container is deposited, based on the estimation of the density (Kg/m3) of the deposited waste. The CaliWASTE container contains inside a compartment equipped with a set of integrated electronic devices: weight sensor, volume sensor, electronic control unit, and a processor that calculates the density of the introduced waste, so that, if the resulting value is within the predefined range of acceptable values, a folding lap opens to an inclined position in which the waste is discharged by gravity.

The collected information is sent to the waste manager, to enable the optimisation of the waste collection routes and schedules.

This patent describes a method for producing gluten-free bakery and patisserie products (both leavened and unleavened) that achieves organoleptic and rheological properties comparable to traditional gluten-containing counterparts, primarily through physical processes while minimizing additives.

A new 'bubble-shaped' column bioreactor for the aseptic cultivation of plant cells in suspension, designed to enable the recovery and replacement of the culture medium and reuse of residual biomass for subsequent operations.

Offshore system dedicated to the generation, storage, and distribution of green hydrogen. At its core is a floating platform equipped with either solar panels or a wind turbine, supplying the clean energy required to pump seawater, desalinate it, and perform electrolysis. The complete system includes an evaporator, a condenser (for water desalination), and an electrolyzer. The hydrogen produced is stored at low pressure using adsorption techniques in the form of metallic hydrides. HydroVERDE also integrates advanced electronic and telecommunication systems to optimize hydrogen loading and unloading. It features IoT-based power electronics monitoring and external communication interfaces for data exchange and geolocation, enabling real-time adaptation of hydrogen production to energy demand.

Bubble column bioreactor for the aseptic cultivation of plant cells in suspension. Its design characteristics also allow for the harvesting of the culture medium, its replacement with another medium, and the reuse of the remaining biomass within the same vessel for a subsequent culture operation.

This patented device resolves these clinical challenges by integrating a circular stapler mechanism directly with a suture thread. The system features a tubular sheath containing a stapling head and a separate anvil with a central mast.During the procedure, the anvil is separated from the stapling head to create a working space. A suture thread is looped around the viscus and tightened against the anvil's mast, gathering and folding the tissue. The anvil is then pulled close to the stapling head, compressing the folded tissue, and the stapler is fired. The staples drive through the double-layered tissue and bend securely against the anvil, locking the purse-string fold and thread firmly in place.

Key Advantages & FeaturesSecure & Vascularized Closure: Unlike linear stapling methods, this device creates a uniform, well-vascularized purse-string tissue border that is securely locked by closed staples, reducing the risk of post-operative leaks.Knotless "Pusher Stick" System: The device includes specialized projections and recesses that allow the surgeon to use a pusher stick to tighten the thread without needing to tie a knot.

Incision-Free Specimen Extraction: Because the thread can be tightened without knotting, the purse-string suture can be temporarily opened and closed.

This allows surgeons to extract the resected, diseased portion of the viscus directly through the hollow organ (e.g., transanally), potentially avoiding the need for an additional abdominal incision during laparoscopic procedures.

Versatile Compatibility: The mechanism can be manufactured as a standalone instrument or designed to securely couple with conventional circular anastomosis staplers currently on the market.
