Self-Contained Three-Dimensional Bioprinter for Applications in Cardiovascular Research
(American Society of Mechanical Engineers (ASME), 2019)Bioprinting is a technique of creating 3D cell-laden structures by accurately dispensing biomaterial to form complex synthetic tissue. The printed constructs aim to mimic the native tissue by preserving the cell functionality ... -
Fingertip-Sized Pressure Sensor for Luer Taper of Three-Way Stopcock in Liquid Channel
(American Society of Mechanical Engineers (ASME), 2019)We developed an easily attachable fingertip-sized pressure sensor (FSPS) for a three-way stopcock in a liquid channel of a heart–lung machine. The FSPS has a double-pipe structure with a semispherical soft film cap on the ... -
Are Medical Grade Bioabsorbable Polymers a Viable Material for Fused Filament Fabrication?
(American Society of Mechanical Engineers (ASME), 2019)Lumbar fusion surgery has grown in popularity as a solution to lower back pain. Surgical site infection (SSI) is a serious complication of spinal surgery, affecting as high as 8.5% of the patient population. If the SSI ... -
Novel Design of a Three-Dimensional Printed Umbilical Cord Clamp: A Proof of Concept Study
(American Society of Mechanical Engineers (ASME), 2019)Parents frequently report complaints regarding the excessive size of the clamp that create concerns of hooking to the clothes and inducing premature separation of the dried cord. We aimed to design three-dimensional (3D) ... -
The Evaluation of a Novel Three-Dimensional Printed Expandable Pedicle Screw Sleeve Insert
(American Society of Mechanical Engineers (ASME), 2019)When used in combination with decompression, spinal fusion is a successful procedure for treating patients with spinal stenosis and degenerative spondylolisthesis. While a number of auxiliary devices have been proposed to ... -
Custom Patient-Specific Three-Dimensional Printed Mitral Valve Models for Pre-Operative Patient Education Enhance Patient Satisfaction and Understanding
(American Society of Mechanical Engineers (ASME), 2019)In recent years, advances in medical imaging and three-dimensional (3D) additive manufacturing techniques have increased the use of 3D-printed anatomical models for surgical planning, device design and testing, customization ... -
Process–Structure–Property Relationships in Selective Laser Melting of Porosity Graded Gyroids
(American Society of Mechanical Engineers (ASME), 2019)Selective laser melting (SLM) can be used to tailor both the geometry and mechanical properties of lattice structures to match bone properties. In this work, a process–structure–property (PSP) relationship for Ti6AL4V ... -
An Investigation Into the Challenges of Using Metal Additive Manufacturing for the Production of Patient-Specific Aneurysm Clips
(American Society of Mechanical Engineers (ASME), 2019)Cerebral aneurysm clips are biomedical implants applied by neurosurgeons to re-approximate arterial vessel walls and prevent catastrophic aneurysmal hemorrhages in patients. Current methods of aneurysm clip production are ... -
Pulse Oximeter for Low SpO2 Level Detection Using Discrete Time Signal Processing Algorithm
(American Society of Mechanical Engineers (ASME), 2019)Oximeter is an important clinical device used for measuring peripheral capillary oxygen saturation (SpO2) in blood and hence accurate results are needed in order to help physicians predict clinical problems in the initial ... -
A Systematic Review of Noninvasive Electrocardiogram Monitoring Devices for the Evaluation of Suspected Cardiovascular Syncope
(The American Society of Mechanical Engineers (ASME), 2019)The aims of this study were (1) to identify research publications studying noninvasive electrocardiogram (ECG) monitoring devices, (2) to define and categorize current technology in noninvasive ECG recording, and (3) to ... -
Percutaneous Ultrasound Gastrostomy: A Novel Device and Bedside Procedure for Gastrostomy Tube Insertion Using Magnetic and Ultrasound Guidance
(The American Society of Mechanical Engineers (ASME), 2019)This paper describes a novel percutaneous ultrasound gastrostomy (PUG) procedure and the CoapTech point-of-care ultrasound magnet-aligned gastrostomy (PUMA-G) device, which were developed to allow the placement of gastrostomy ... -
Design and Modeling of a Three-Degree-of-Freedom Articulating Robotic Microsurgical Forceps for Trans-Oral Laser Microsurgery
(The American Society of Mechanical Engineers (ASME), 2019)Trans-oral laser microsurgery (TLM) is a surgical procedure for removing malignancies (e.g., cysts, polyps, tumors) of the laryngeal region through laser ablation. Intraoperative microsurgical forceps (i.e., microforceps) ... -
Compact Two Degrees-of-Freedom External Fixator System for Correction of Persistent Clubfoot Deformity
(The American Society of Mechanical Engineers (ASME), 2019)Bone deformities are often complex three-dimensional (3D) deformities, and correcting them is difficult. To correct persistent clubfoot deformity in adolescents or adults, an external fixator is sometimes used to encourage ... -
The Role of Tissue Slip Feedback in Robot-Assisted Surgery
(The American Society of Mechanical Engineers (ASME), 2019)Slip, or accidental loss, of grasped biological tissue can have negative consequences in all types of surgery (open, laparoscopic, robot-assisted). This work focuses on slip in robot-assisted surgery (RAS) with the goal ... -
Portable Device for Measuring Blood Test Hemolyzed Samples Based on Computer Vision and Neural Network
