Patent number: 10758395Abstract: A physical rehabilitation device for the treatment of a medical condition of the foot known as plantar fasciitis includes a splint which is connected to the toe and ankle of a patient. The splint can be used in a method for treating plantar fasciitis known as “dynamic splinting”. This device allows the patient to bend the ankle and thus dynamically change the flexion in the foot of the patient. The device itself is unique, but the method of treatment made possible by this device is also unique.Type: GrantFiled: August 25, 2017Date of Patent: September 1, 2020Assignee: Arthrology Designs, LLCInventor: Derek Amanatullah

Publication number: 20200222063Abstract: A modular system for total knee arthroplasty includes a modular trial implant assembly. The modular implant assembly includes an elongate shaft configured for insertion into an elongate cavity in a bone, a reamer removably coupleable to the elongate shaft via a connection that allows the reamer to rotate while the elongate shaft remains in a substantially fixed angular orientation. The reamer has an outer surface that tapers toward the distal end configured to form a tapered cavity in an end of a bone in which the reamer is inserted and rotated. The modular trial implant assembly further includes a trial implant removably coupleable to a proximal end of the reamer. A modular final implant assembly includes an elongate stem, a tapered body and an implant body, each having a size and shape that can substantially correspond to a size and shape of the elongate shaft, the reamer and the trial implant, respectively.Type: ApplicationFiled: March 27, 2020Publication date: July 16, 2020Inventor: Derek Amanatullah

Patent number: 9468570Abstract: The present invention is a device and method for manufacturing such a device which is a significant and non-obvious improvement over previous methods of removing plaster or fiberglass casts used for medical treatment. Current cast saw blades create enough heat through friction to burn patients upon the removal of a plaster of fiberglass cast. This device is an improved cast saw blade design which substantially reduces the risk of thermal burns to patients during the process of removing plaster or fiberglass medical casts. The present invention includes a saw blade design which inhibits a rise in the surface temperature of the cast saw blade during use by using a core material (i.e., Gallium) within the blade, the core material having a lower melting temperature than the blade material, as a heat sink.Type: GrantFiled: December 10, 2013Date of Patent: October 18, 2016Inventor: Derek Amanatullah
