An ear canal clamp for small animals includes a base and a clamping mechanism. The clamping mechanism includes two clamping arms movably mounted on the base, a biasing member mounted on the base and constrained between the clamping arms, and two ear canal positioning members mounted respectively to the clamping arms and facing each other. The clamping arms are configured to move toward each other and compress the biasing member to increase the distance between the ear canal positioning members. A biasing force generated by the biasing member when compressed is used to push the clamping arms to move oppositely with respect to each other.

A novel apparatus to remove a foreign object embedded in an animal's paw is disclosed herein. In a general embodiment, the apparatus has an adhesive base that attaches to the animal's paw. When the animal steps on the apparatus with its paw, the adhesive base gently and painlessly extracts the foreign object from the animal's paw. The adhesive base is separated from the paw with the foreign objects adhere to the adhesive base.

A closure system for delivering a sealant to an arteriotomy. A distal section of the closure system can include overlapping inner and outer sleeves that can expand with expansion of the sealant. A proximal section of the closure system can include a handle portion and a sheath adapter extending from the handle portion. The handle portion can include one or more actuators that when depressed or engaged can assist in deployment of the sealant in the arteriotomy and can further include tamping of the sealant and/or retraction of an expandable member. The sheath adapter can removably engage a side port or an irrigation line of a standard procedural sheath. When the sheath adapter is secured to the procedural sheath, movement of the closure system can also move the procedural sheath.

A device for occluding a perforation in a blood vessel includes an expandable member. The expandable member includes a central expandable balloon disposed between a proximal and a distal balloon, wherein the proximal and distal balloons each contain first and second compositions, respectively. The proximal, central and distal balloons have respective stiffnesses, and the central balloon has a third stiffness that is less than the first and second stiffnesses. Upon expansion, the central balloon causes the proximal balloon and the distal balloon to substantially simultaneously release the first and second compositions, thereby allowing the first composition and the second composition to combine in-situ and form, therein, a biocompatible foam to occlude a perforation within the vasculature.

The present disclosure provides an apparatus generating spinal cord contusive model of animals, including an external fixation member fixed outside a body of an experiment animal, an impactor configured to impart a spinal cord of the experiment animal, and an impactor guide member fixed to the external fixation member to guide a fall of the impactor, wherein the impactor is provided with an acceleration sensor.

Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices include the use of a RBC flocculant, such as polyDADMAC, and an approximate blood hematocrit for the type of animal, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal type hematocrit, and a calculated RBC packing ratio value for the collection device. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.

A method and process for providing three dimensional (3-D) virtual image of a patient in metaverse or 3-D hologram for surgical or other procedures, wherein the avatar of a medical practitioner, imitating the actions of the practitioner performing the procedure, can visually identify the organs and the location of the instruments in real-time inside patient. The image data stream generated in real time can be saved in a data base for later re-creation of the image. The re-creation of the image with spatial coordination and updating in time is usable as a review and a teaching/training tool. The implemented Metaverse provides all details collected and combined from the multiple imaging systems. It is usable as a diagnostic tool, a practice tool a teaching tool and real time direction and feedback tool by the medical community for procedures. The real-time image in Metaverse provides critical visual capabilities during procedures.
