Nanotexturing for Biomedical Implants
It is known the foreign body response to implants, such as breast implants, includes a “walling off” of the implant, or a capsule formation. Previously, texturing has been shown to reduce this capsule formation, using methods such as polyurethane coatings [11-15]. A new proposed texturing method is …

Polymer Composite Spinal Disc Implants
The goal of this research study was to create an artificial annulus fibrosus similar to that of the natural intervertebral disc, as well as find preliminary results for vertebral endplate connection and nucleus pulposus internal pressure, for the correction of disc degeneration in the spine. The …

Spinal cord implants for nerve regeneration
It has only been in the last couple decades that the potential for regeneration in the spinal cord became accepted. However, there is still no proven method for enabling this regeneration. An implant model was developed to help aid in repair, recovery, and regeneration in the spinal cord following …

ELECTROSPINNING ROBOT FOR REGENERATIVE COATING OF IMPLANTS
… biocompatible soy based scaffolds. Craniofacial implants are often complex in geometry, and conformal bandages are particularly hard to produce in these areas. Soy based scaffolds will be produced for 3D-printed replicas of these situations. Finally, the methods developed across this aim enables …

Development of Precision 3D-Printed Medical Implants
… Metal 3D printing enables complex porous implants that enhance osseointegration, reducing aseptic loosening risks. Furthermore, in this research, the osteogenic responses to pre-designed structures of porous titanium alloy samples to optimize bone-implant integration was evaluated. Bone …

Enhancing voice pitch perception in cochlear implants
Cochlear implants (CIs) are among the most successful sensory prostheses in the world, partially restoring hearing and, to many users, speech perception. However, they suffer in more complex tasks such as pitch perception. In particular, poor voice pitch perception affects CI users’ ability to …

Screw fixation of implants to the spine
Bone screws are used to fix various implants to the human spine. Screw fixation can be difficult in osteoporotic bone because of its reduced strength. This research aimed to investigate screw fixation techniques in the spine. A questionnaire study, representing British and Irish spine surgeons, …

Sustained-release implants for intraperitoneal cisplatin delivery
The objective of this work was to develop materials for continuous low-dose delivery of cisplatin directly into the abdomen, also known as intraperitoneal (IP) chemotherapy. IP chemotherapy can help treat peritoneal metastasis in many advanced gynecologic and gastrointestinal cancers and has shown …

Using cold spray to package electronic implants
… in electronics manufacturing, electronic implants keep decreasing in size and are moving towards integrated-circuit (IC) based designs. As implant electronics become significantly smaller with the use of ICs, traditional implant packaging become a limiting factor on implant …

Development of biodegradable implants for sustained drug delivery
… thesis, reservoir and matrix-type subcutaneous implants were produced and demonstrated adjustable release rates for several compounds. Reservoir-type implants were produced using 3D printing and showed promising and adjustable in vitro release rates for model compounds: methylene blue, ibuprofen …

Wireless Communication with Medical Implants: Antennas and Propagation
With the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. Extended range and …

Wh-Question Processing in Children with Cochlear Implants
<p>Children with cochlear implants (CIs) have exhibited difficulty accurately answering and producing wh-questions. The syntactic construction of wh-questions include syntactic movement, whereby the wh-question phrase that replaces the subject or object noun is fronted to the beginning of the …
