Implants: Protective Membrane Reduces Tissue Buildup

  • Magazine Article
  • TBMG-35775
Published 2020-01-01 by Tech Briefs Media Group in United States

Scientists have developed a special protective membrane made of cellulose that significantly reduces the buildup of fibrotic tissue around cardiac pacemaker implants, as reported in a recent issue of the journal Biomaterials.1 The protective membrane could greatly simplify surgical procedures for patients with cardiac pacemakers.

When a patient experiences 70 percent or greater stenosis in the carotid artery — a condition that can cause lack of cerebral blood flow, stroke, and in some cases, death — surgeons perform a procedure known as carotid endarterectomy (CEA) to remove the plaque causing the artery stenosis.1,2 The procedure consists of a longitudinal incision made from the common to the internal carotid artery, allowing for removal of the plaque that deposits in the bifurcation.

A transistor has been made from linen thread, enabling the creation of electronic devices made entirely of thin threads that could be woven into fabric, worn on the skin, or implanted surgically for diagnostic monitoring. The flexible electronic devices could enable a range of applications that conform to different shapes and allow free movement without compromising function.

Camera Enables Surgeons to More Easily Identify Cancerous Tissue

Published 2019-11-01 by Tech Briefs Media Group in United States

Many surgeons rely on sight and touch to find cancerous tissue during surgery. Large hospitals or cancer treatment centers may also use experimental near-infrared fluorescent agents that bind to tumors so surgeons can see them on specialized displays. These machines are costly, making them difficult for smaller hospitals to procure. They also are very large, making them difficult to fit into an operating suite and integrate smoothly into surgery, and they require the lights to be dimmed so the instruments can pick up the weak fluorescent signal, making it difficult for the surgeons to see.

Hydrogel Fights Orthopedic Bone Infections

Researchers have a developed a double-duty hydrogel that both attacks the bacteria and encourages bone regrowth with a single application containing two active components.

Tiny Biodegradable Circuits Release Painkillers Inside the Body

Published 2019-09-01 by Tech Briefs Media Group in United States

Patients fitted with an orthopedic prosthetic commonly experience a period of intense pain after surgery. In an effort to control the pain, surgeons inject painkillers into the tissue during the operation. When that wears off a day or two later, the patients are given morphine through a catheter placed near the spine. Yet catheters are not particularly comfortable, and the drugs spread throughout the body, affecting all organs.
