Enhanced Biocompatibility of Porous Nitinol [PDF]

Journal of Materials Engineering and Performance, 2009
Porous Nitinol (PNT) has found vast applications in the medical industry as interbody fusion devices, synthetic bone grafts, etc. However, the tendency of the PNT to corrode is anticipated to be greater as compared to solid nitinol since there is a larger surface area in contact with body fluids.

On the experimental testing of fine Nitinol wires for medical devices [PDF]

, 2011
Nitinol, a nickel titanium alloy, is widely used as a biocompatible metal with applications in high strain medical devices. The alloy exhibits both superelasticity and thermal shape memory behaviour. Basic mechanical properties can be established and are

Differential Scanning Calorimetry (DSC) Analyses Of Superelastic And Nonsuperelastic Nickel-Titanium Orthodontic Wires [PDF]

, 1996
The purpose of this study was to determine the transformation temperatures for the austenitic, martensitic, and rhombohedral (R) structure phases in representative as-received commercial nitinol (NiTi) orthodontic wire alloys, to reconcile discrepancies ...

Low-cost prototyping of nitinol wires/frames using polymeric cores and sacrificial fixtures with application in individualized frames anchoring through the atrial septum

Scientific Reports, 2023
Self-expanding frames for minimally invasive implants are typically made from nitinol wires and are heat treated to maintain the desired shapes. In the process of heat treatment, nitinol structures are placed in a high-temperature oven, while they are ...

Functional architected Al–NiTi interpenetrating phase composites with primitive aluminum cores fabricated using spark plasma sintering

Journal of Materials Research and Technology
Interpenetrating phase composites (IPCs) are composite materials characterized by co-continuous and interlocked matrix and reinforcing phases. This distinctive combination often leads to superior performance compared to conventional composite assemblies.

Delayed pericardial effusion or tamponade following left atrial appendage closure: A single-center experience

Journal of the Formosan Medical Association, 2023
Background: Pericardial effusion or pericardial tamponade (PE/PT) is a relatively common complication of left atrial appendage closure (LAAC). However, delayed PE/PT is rare with limited data.

Observations and models for needle-tissue interactions [PDF]

, 2009
The asymmetry of a bevel-tip needle results in the needle naturally bending when it is inserted into soft tissue. In this study we present a mechanics-based model that calculates the deflection of the needle embedded in an elastic medium.
