A therapeutic device and method for its use are presented. The appliance and method are adapted to realign and straighten the toes of the foot in order to treat the effects of hammertoe, bunions, Morton's neuroma, and the like. Effectively, a harness is placed about the heel of the foot, the harness consisting of a foot strap and heel strap. Sleeves are placed about the particular toes of interest, being as few as one and as many as all of the toes on a foot. Elastic straps are interconnected between the toe sleeves and the foot strap in order to impart a force to the associated toe to straighten and/or realign the toe consistent with correcting a particular malady. The elastic strap may be connected and disconnected by means of hook and loop fasteners at the end of the strap and maintained upon the toe sleeves and foot strap. The positioning of the strap with respect to the toe sleeve and the foot strap effects the direction of the force applied to the toe in accordance with the malady to be treated.

The subject invention provides devices and methods for alleviating discomfort associated with neuroma formation. The devices and methods of the invention effectively use the body's natural response of reconstructing implanted biomaterials to minimize the size of, isolate, and protect a neuroma. In preferred embodiments, the subject device is a cylindrical cap, wherein the internal chamber of the cylindrical cap physically partitions the nerve to enable an arrangement of nerve fibers (as opposed to haphazardly arranged nerve fibers often produced in neuromas). In addition, the cap's material remodels into a tissue cushion after implantation, which protects the neuroma from being stimulated and inducing pain.

The present invention generally relates to improved medical devices, systems, and methods. In many embodiments, devices, systems, and methods for amputating a limb of a patient are provided. In many embodiments, devices, systems, and methods may provide chronic denervation of one or more nerves of a patient as part of a therapeutic treatment. The methods may employ cold for the prevention of neuromas or fibromas associated with amputation of a limb of a patient. Embodiments of the invention include needles that can be advanced through skin or other tissues to cause axonotmesis of a target nerve of the patient and to repeatedly interrupt a regeneration of the nerve so as to provide therapeutic chronic denervation of the target nerve. The therapeutic chronic denervation may delay the formation of neuromas or fibromas in a patient's residual limb and/or may provide long lasting and permanent pain relief associated with the target nerve.

Footwear including an insole formed for relieving pressure on a common digital nerve of a foot. The insole has heel, mid and forefoot sections. The forefoot section of the insole is formed with a pad having a neuroma pad section which underlies the third and fourth metatarsal heads of the foot, so that when a bottom of the foot is placed on the insole, the neuroma pad section applies an upward force to the bottom of the foot sufficient to spread the third and fourth metatarsal heads away from one another and thereby relieve pressure on the third common digital nerve to reduce the risk of neuroma. In other embodiments, the pad is formed as a separate pad for placement in footwear. An insole designed for use with thonged footwear is also disclosed.

The invention relates to synthesis of an emodin derivant with an anti-tumor function, in particular to a hydroxyl whole-protection didecyl quaternary ammonium with anti-tumor activity and a preparation method thereof. The didecyl quaternary ammonium is decyldimethylchlorosilane-[2-(4,5,7-trimethoxy-9,10-anthraquinonyl)methyl]. The preparation method is characterized by taking emodin as a raw material to carry out a series of synthetic reaction. The emodin derivant of the invention has proliferation inhibition action of different degrees on liver cancer HepG2, gastric cancer BGC, neuroma SH-SY5Y, gastric cancer AGS, cervical cancer Hela and the like as well as normal human embryonic lung fibroblast HELP and can be used for preparing medicines for treating cancers.

The invention provides application of acellular nerve hydrogel to preparation of a peripheral nerve injury repairing composition. The peripheral nerve injury repairing composition is prepared by using the acellular nerve hydrogel, so the peripheral nerve regeneration microenvironment can be simulated well, extension and myelination of axon can be promoted, the PSD95 expression level of nerve cells is reduced, and occurrence of pathological neuralgia and neuroma is inhibited. An electrophysiological experiment proves that although the acellular nerve hydrogel inhibits formation of cynapse between the nerve cells, the acellular nerve hydrogel does not influence generation of action potential and conduction along axion and can repair peripheral nerve injury well.

The invention belongs to the technical field of biological materials and nerve injury repairing, and particularly relates to a decellularized epineurium catheter and a preparation method thereof as well as application to repairing of a peripheral nerve injury. The biological characteristic of the decellularized epineurium catheter for a pig is researched from such aspects as the porosity, the swelling rate, the in vitro degradation rate and the cytotoxicity test, and the immunogenicity of the catheter is also researched. According to the decellularized epineurium catheter and the preparation method thereof, a rat sciatic nerve transversal injury model is built; after being subjected to microsurgical suturing, a nerve stump line is covered with the decellularized epineurium catheter so as to research the effects of promoting regeneration of nerves, preventing nerve adhesion and formation of nerve tumors. The invention provides the decellularized epineurium catheter which can effectively reduce surrounding nerve adhesion and reduce the occurrence rate of the nerve tumors, and a novel repairing material is provided for repairing of war traumatic surrounding nerve injuries and treatment of causalgia caused by the nerve injuries.

The present invention provides a peripheral nerve growth scaffold including poly ε-caprolactone (PCL) and microgrooves on an inner surface of the scaffold, the scaffold being adapted for use in treatment of damaged peripheral nerves. The microgrooves are suitably arranged as a pattern or array and preferably comprise sloping side walls, which arrangement has been found to provide a favourably environment for nerve and Schwann cell growth and proliferation. Experimental results demonstrate directed and aligned growth, which suitably reduces the rate of formation of neuromas. Embodiments comprising a PCL-PLA blend of the sloping side wall and a groove width greater than the spacing between adjacent grooves has been found to be particularly effective for directed cell growth and proliferation.

A method of predicting a tumor of the auditory nerve based on the latency of the auditory brainstem response (ABR) in the presence of a tumor. The ABR is masked using white noise and derived bands are calculated. The wideband (WB) response is also recorded. The derived bands are transformed and summed to form a SUM, and the transform of the WB is also taken. The ratio SUM/WB is taken, and the result is compared to normal ratios to predict the presence of a tumor.
