Canaloplasty for Open-Angle Glaucoma

January 13, 2020 Medical Technology Directory

Health Problem: Glaucoma is a disease of the optic nerve characterized by loss of retinal ganglion cells; remodeling of the lamina cribrosa; structural changes to the nerve; elevated intraocular pressure (IOP); and progressive, irreversible loss of vision leading to blindness. Open-angle glaucoma (OAG) is associated with partial blockage of the flow of aqueous humor. Technology Description: Canaloplasty (CP) is a minimally invasive glaucoma surgery that utilizes a specially designed microcatheter to dilate aqueous humor collector channels to reduce IOP. The microcatheter alleviates obstructions in the Schlemm canal (SC) by pushing through them physically and by injecting high-molecular-weight viscoelastic to viscodilate the...

Proton Beam Therapy for Treatment of Chordoma and Chondrosarcoma of the Skull Base

December 31, 2019 Medical Technology Directory

Health Problem: Chordomas are rare primary bone tumors originating from remnants of the embryonic notochord and most commonly arising in the skull base (32%), mobile spine (33%), and sacrum (29%). Chondrosarcomas, which arise from cartilage, are usually low-grade, indolent, invasive tumors that cause morbidity by compressing skull base neurovascular structures. Chondrosarcomas account for approximately 30% of primary bone cancers. Approximately 1% to 2% of chondrosarcomas arise in the skull base. In addition to the risk of mortality, skull base chordoma and chondrosarcoma can cause morbidity that can severely impact patients' quality of life (e.g., hearing loss, double vision). Both malignancies...

Thermal Pulsation for Chronic Dry Eye Syndrome and Meibomian Gland Dysfunction

December 31, 2019 Medical Technology Directory

Health Problem: Dry eye disease (DED) is a type of ocular surface disorder. Meibomian gland dysfunction (MGD) contributes to DED in approximately 60% of patients. The meibomian glands are present in the upper and lower eyelids and they secrete lipids that are an important component of tears. The oily lipids float to the surface of tear solution that covers the eyes, forming a thin barrier between air and water that slows evaporation to keep the eye surface from drying out. An estimated 3.2 million women and 1.7 million men aged 50 years and older are affected by DED in the...

Novocure (Tumor Treating Fields) for Treatment of Glioblastoma

December 27, 2019 Medical Technology Directory

Health Problem: Glioblastoma (GBM) is the most prevalent primary malignant intracranial tumor, representing as much as 16% of primary brain tumors. GBM is a fast-growing glioma that develops from glial cells in the brain; it is also referred to as a grade IV astrocytoma. In the United States, the annual incidence of GBM ranges from 0.59 to 3.69 cases per 100,000 people. Technology Description: Tumor treating fields (TTF), also referred to as the Optune device, is the novel method of cancer treatment that involves emitting alternating electric fields to disrupt the rapid cell division exhibited by cancer cells. TTF therapy has...

Reflectance Confocal Microscopy for Diagnosis of Cutaneous Melanoma

December 20, 2019 Medical Technology Directory

Health Problem: Melanoma is a malignant tumor of melanocytes, the pigment-producing cells of the skin that derive embryonically from the neural crest. This malignant cancer occurs primarily in adults and the most favorable prognoses are obtained when lesions are thin, minimally invasive, and confined to the primary site. Conversely, the probability of cure decreases dramatically if melanoma metastasizes locally via the lymphatics or systemically through the bloodstream. Despite efforts by public health officials to educate the public about the dangers of sunbathing, sunburns, and tanning beds, approximately 96,480 people in the United States will develop melanoma in the year 2019...
