Using celiac artery access and an L-shaped microcatheter, the mouse model enables hepatic drug infusion for genetic and tumor immunology research.

Plastic tools can wear or break outdoors; this emasculator uses a metal base and replaceable blades to improve durability and maintenance.

Camming surfaces and slots draw tibial bone fragments together while removable plugs limit plate contact and bone-surface compression.

A ramped compression hole closes the wedge, while polyaxial screws help avoid elbow-structure interference and stabilize ulna fragments.

Segmented discs and a biocompatible sheet reduce the septal profile of PFO closure devices, resolving bulkiness issues while ensuring complete occlusion.

Adjustable cable loops guide small livestock orientation, resolving adaptability issues with standard large-animal aids.

Segmented tines transition from linear to coiled states, enabling minimally invasive cardiac defect closure without open heart surgery.

An obstetrical device injects air through apertures to break suction between the fetal head and maternal tissues, reducing extraction force.

Inflatable balloon seals vessel puncture via detachable distal sealing member, avoiding suture-induced tissue damage.

Segmented PFO closure clips compress overlapping septal tissue layers, resolving anatomical conformability issues that cause residual leaks.

A reversible clip mechanism secures surgical implants to deployment arms using a locking bar and rotating joint.

A collapsible occluder with an adjustable center joint resolves anatomical conformability issues by adapting to different tissue thicknesses.

A resorbable hemostasis device clamps the vessel wall to seal punctures.

Disposable applicator tubes eliminate laborious sterilization procedures while preventing cross-contamination risks in veterinary applications.

An elastic protrusion anchors a closure device against opening edges, eliminating displacement risks and reducing blood clot formation.

An extraluminal plug with one-way barbs anchors in the tissue tract to stop migration from blood pressure, reducing nursing time.

Interlocking wings close the patent foramen ovale, reducing leakage and thrombus risk.

Segmented tines and self-actuating wings compress graft vessels against target arteries, ensuring sealing without penetration in microvascular surgery.

Locking funnel cap secures PFO occluder via radial force, preventing dislodgement and residual leaks.

A spring-loaded ear canal clamp uses opposing arms to align small animal ears without manual adjustment.

Stamping sheet metal into a pivoting fastener reduces manufacturing costs while maintaining reliable tissue fastening.

A navel umbilical cord tab with a C-shaped upper level and flange-like lower level supports the cord during cleaning procedures.

Twisting elongate members deploy dual occluding bodies simultaneously, resolving complexity in secure septal closure.

An expandable anchor locator stabilizes vessel wall contact, resolving misalignment risks during tissue puncture closure.

An occlusion device with an adjustable tether adapts interseptal length to patient anatomy.

A surgical mesh incision guide uses a movable closing element to draw alignment surfaces together for precise wound edge approximation.

Ratchet locking hub compresses collagen sponge toward anchor to prevent repositioning and over-tamping during vascular closure.

Disposable foam-covered clamps apply distributed pressure to enlarged uterine vessels, reducing blood loss and shortening suturing time without tissue damage.

A 3D-printed lavage instrument with a flexible curved tip directs fluid to remove chondroids from equine guttural pouches.

Tissue hooks engage vessel walls to close access sites, reducing hemorrhage risk and recovery time.

Integrated shaft channels organize catheter tubes to prevent tangling and view obstruction during gynecological procedures.

A bioresorbable sealing tip releases via a low-force member to secure vascular punctures.

Reversible Nitinol clip closes catheter holes without enlarging them, enabling reliable hemostasis and easy removal.

Segmented bone plates with angled K-wire slots achieve precise angular correction while maintaining joint stability.

An off-center shaft rocks a convex pad along the catheter track, reducing user fatigue and injury risk during manual vascular compression.

A deformable applicator releases cyanoacrylate adhesive through a frangible ampoule and flow restrictor for precise incision closure.

A collagenous vascular puncture sealing device expands to block vessel openings, eliminating prolonged bleeding and external pressure requirements.

A spring-loaded tissue fastener deploys anchor arms to approximate and tighten the lower esophageal sphincter via an endoscope.
