Stamping or Machining: What Do You Choose for Your Metal Devices?

You’re developing a metal medical device and balancing a budget, deadlines, design considerations, and more. Which process do you choose—stamping or machining? MD+DI asked metal manufacturing veteran Steve Santoro, executive vice president for Micro, to compare the two processes as well as look forward to the future in metal manufacturing. Santoro has been at Micro since 2002 and has been in the contract manufacturing industry his entire career.

Santoro: The main determinant when considering stamping versus machining has to do with the fit, form, and function of a component coupled with the geometry of the part and material used. If a medical device is designed for an indefinite number of uses, then machining works best, as it produces complex parts that support durability. For products that are meant to be used just one time, stamping is a better approach as it can produce precision parts that tend to be less durable. Volume can also be a significant driver in the decision-making process. When several million components a week are needed, such as ligation clips, this can be easily achieved with stamping. To machine such quantities might require 100 machining centers. Thus, scaling to this degree with machining may not be practical in terms of capital outlay. Tooling...

In this study, we applied a data-driven approach to construct a stroke atlas of the brain using hierarchical density clustering in large number of infarct lesions, assuming that voxels/regions supplied by a common end-artery tend to infarct together.MethodsA total of 793 infarct lesions on MRI scans of 458 patients were segmented and coregistered to MNI-152 standard brain space. Applying a voxel-wise data-driven hierarchical density clustering algorithm, we identified those voxels that were most likely to be part of same infarct lesions in our dataset. A step-wise clustering scheme was applied, where the clustering thresho...

Stroke involving some areas of the cerebral hemisphere, such as insula, amygdala, and lateral hypothalamus, may cause changes in autonomic control of cardiac function. A 58-year-old woman presented to the emergency department for acute onset of left facial-brachial-crural hemiparesis and dysarthria. A brain CT scan showed subacute ischemic lesion with hemorrhagic infarction in right insular-rolandic cortex. Over the next few days ECG showed severe bradycardia with elongation of QTc, significative pauses (5 seconds), runs of nonsustained ventricular tachycardia and torsades de pointes.

A 24-year-old woman was admitted to our hospital after convulsive status epilepticus. A cerebral magnetic resonance venography revealed a persistent fetal falcine sinus. Additionally, the posterior third of the superior sagittal sinus was hypoplastic and the abnormal deep venous drainage was accompanied. These abnormalities had already been detected by magnetic resonance imaging several years ago. In the present scan, we discovered a sinus thrombosis in the hypoplastic superior sagittal sinus. In the cerebral angiography, we observed delayed venous return in the left parieto-occipital lobe and hypothesized that cerebral ve...

The cognitive deficits in these patients are known to be correlated with structural brain changes, such as white matter lesions and lacunae, and resting-state functional connectivity in brain networks. However, the associations between changes in brain glucose metab...
