medical illustration of These illustrations were created for a medical device company to describe common spinal disc injuries.  Intervertebral discs act as cushions between vertebrae in the spine. Degenerative disc disease is a term used to describe the changes to spinal discs as we age. When a disc bulges, it can put pressure on the spinal nerves, causing pain. In herniated discs, the jelly-like fluid within the disc leaks out due to a rupture in the annulus. This also causes pressure on the spinal nerves and pain.
medical illustration of Journal cover illustration about the difficulties and options for the treatment of superficial femoral artery disease (SFA).
medical illustration of Spinal fusion is the most widely performed surgery for scoliosis. This illustration was intended to demonstrate a spinal fixation device for correction of posterior spine defects.
medical illustration of The hiatus is an opening in the diaphragm (the muscular wall separating the chest cavity from the abdomen). Typically, the esophagus goes through the hiatus and attaches to the stomach. In a hiatal hernia the stomach bulges up into the chest through that opening. This illustration depicts a hernia repair with a graft.
medical illustration of Cardiogenic shock occurs when the heart can't pump enough blood to the body. Cardiogenic shock is the leading cause of death in acute myocardial infarction. Symptoms of cardiogenic shock include rapid breathing and heartbeat (tachycardia), mental confusion, sweating, weak pulse and poor tissue perfusion.
medical illustration of This illustration demonstrates a rectovaginal fistula repair with a biological material plug. The procedure repairs a fistula or hole between the vagina and rectum. This illustration was created for a medical device manufacturer’s marketing and educational materials.
medical illustration of Atherectomy is a minimally invasive endovascular technique for removing plaque build-up from blood vessels in the heart and in other areas of the body. In catheter-directed atherectomy, an interventional radiologist uses a catheter to reach the site of the blockage and either cut, shave, sand or vaporize the clot with lasers.
medical illustration of Esophagogastric fundoplication procedure to relieve chronic acid reflux caused by gastroesophogeal valve defect.
medical illustration of Otitis externa refers to an inflammation of the dog's outer ear, which is commonly caused by bacterial or yeast infection.  This illustration was created to demonstrate the mode of action for a veterinary company’s new ointment.
medical illustration of Dislocation is an uncommon, but potential complication to hip replacement surgery. This illustration demonstrates the failure of a metal on metal hip implant.
medical illustration of The outside of the bone consists of a layer of connective tissue called the periosteum. The outer shell of the long bone is compact bone with a deeper layer of cancellous bone (spongy bone) which contains red bone marrow. The interior part of the long bone is the medullary cavity with the inner core of the bone cavity being composed of yellow marrow. This image was used in patient education materials.
medical illustration of Occipital Nerve Stimulation (ONS) therapy consists of applying mild electrical stimulation to the nerves via wires implanted just under the skin, near the occipital nerves at the base of the head. The wires are connected to an implanted battery that generates the stimulation, which interferes with pain signals and may evoke the sensation of tingling or paresthesia. This illustration was created as a 3D image with 2D illustration enhancements.
medical illustration of Journal cover illustration about transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis at intermediate or low risk for surgery. Currently, the two TAVR devices approved in the US are indicated only for patients at high risk or extreme risk/inoperable, but the literature is now showing that TAVR benefits patients intermediate or low risk for surgery.
