7 medtech stories we missed this week: June 30, 2017
[Image from unsplash.com]From ConforMIS touting its knee replacement study to Consulting Radiologists’s new breast cancer detection tool, here are seven medtech stories we missed this week but thought were still worth mentioning. 1. Study: Low-dose CT scanning improves Ankylosing Spondylitis assessment A new study has shown that low-dose computed tomography (LD-CT) is more sensitive than X-rays for monitoring disease progression in people who have Ankylosing Spondylitis, according to a June 15 press release. LD-CT has previously been proven to be sensitive and reliable when assessing bone growth in different patients. The new study is designed to compare how well it can show the formation of new bony growth (syndesmophytes) and an increase in size in syndesmophytes. The study showed that LD-CT was more consistent when detecting these bone growths in AS patients than X-rays. About 30% of the patients in the study showed bony proliferation at three or more sites using LD-CT, while only 6% showed on conventional X-rays. The lead author was Dr. Anoek de Koning from the Leiden University Medical Centre in Leiden, Netherlands. 2. ConforMIS touts total knee replacement implant study ConforMIS announced in a June 13 press release announced study results for total knee arthroplasty (TKA) patients treated with customized individually made (CIM) implants or standard off-the-shelf (OTS) implants. There were 248 participants in the study. About 3.3% had events at discharge with...
Conclusions: The ANDY can be used to track the syringe used for each patient. The barcode can be read while the syringe rotates in the main body of the ANDY with a built-in omnidirectional scanner. Collection of information during syringe disposal can facilitate stock management. This system could also be extended to other types of consumable medical devices, although it would still be a challenge to differentiate each medical device. PMID: 30788181 [PubMed]
To evaluate the ability of pre-procedural CTA to predict the technical success of embolization of post-EVAR type II endoleaks arising from lumbar arteries.
The objective of this compound is to decrease the rate of rectal toxicity related to radiation therapy, by creating a gap between the prostate and rectum. Secondary benefits include decreased urinary complications and improved sexual quality of life. The hydrogel spacer maintains space for approximately 3 months, and is absorbed in about 6 months.
To evaluate the efficacy and clinical impact of 3 Tesla in-bore trans-rectal magnetic resonance-guided biopsy (3T MRGB) for prostate cancer (PCa) detection based on PIRADSv2 in patients with either suspected prostate cancer or under active surveillance.
A pulmonary arteriovenous malformation (PAVM) is an anomalous connection between a pulmonary artery and a pulmonary vein that lacks a capillary bed. The most common symptoms of PAVM are dyspnea, exercise intolerance, migraine, stroke or transient ischemic attack, and lung hemorrhage. The treatment of choice is transcatheter embolization with the most common embolic devices being coils (multiple manufacturers) or Amplatzer plugs (AVP) (St. Jude Medical, Plymouth, MN) to occlude the malformation. The newest embolic device for PAVM occlusion is the microvascular plug (MVP) (Micro Vascular Plug System, Medtronic, Minneapolis, MN).
Numerous studies conclude sphenopalatine ganglion blockade (SPGB) with local anesthetic provides effective treatment for cephalalgias with few adverse events. The purpose of this study was to demonstrate safety and efficacy of SPGBs.
To develop a model to estimate drug dose delivered to the liver following transarterial chemoembolization (TACE) with radiopaque drug-eluting beads (RO DEB) based on bead density and cone-beam computed tomography (CBCT) in a woodchuck hepatoma model.
We describe our experience using MRI fused CBCT guidance for prostate biopsy. There are no published reports on the use of CBCT guidance in prostate biopsies. We hypothesize this technique will have an adequate safety profile while accurately detecting prostate cancer.
Computed tomography (CT) interventions are often performed using a helical acquisition technique while the operator is in a control room. We compare an axial technique using a gantry-side pedal to the helical technique for chest biopsies in terms of time, number of acquisitions, and radiation dose to operator and patient.
CT-guided interventional procedures, in particular ablations and complex orthopedic procedures, can at times require the use of substantial radiation doses. A theoretical model for skin dose based on the definitions of CTDIvol and CTIDw has been published, but not validated experimentally. The aim of this study was to validate this model and benchmark against a typical mix of helical and axial scanning during CT-guided procedures.
