Abstract:
Radiofrequency ablation (RFA) is a medical procedure used for treatment of cardiac disorders such as arrhythmia or destruction of cancerous tumors in lung, kidney, breast, liver or any other dysfunctional tissue diseases. RFA is also used for treatment of varicose veins, severe chronic pain as well as many other medical uses.

RFA Side Effects and Complications:
Although radiofrequency ablation is a relatively safe procedure, serious complications and side effects can occur. Potential side effects include tissue charring and blood coagulation, blood clot and stroke, cardiac perforation, pulmonary vein stenosis, etc.

Solution:
The novel design of the “RFA Thermal Imaging” is based on the medical grade thermal imaging (thermography) infrared camera and associated software. This system allows for real-time monitoring and analysis during the ...

The goal to be accomplished is to have a robot work collaboratively with a person in a patient care setting without electrical communication (e.g., Remote Control). By having a robotic bed side assistant available to assist with basic tasks within hospitals or nursing homes, the staff can be more focused on those who are in need while those who are stable can be cared for. To accomplish the task of a robot working with a patient, I broke the project up into several different tasks. These tasks include, Face Tracking, Impedance Control, and a vision system detecting angles with robotic response (Angular Response).

The Face Tracking system has the robotic arm follow the user’s face within a 2D plane ...

ROSES is a Robotic System for Endovascular Surgery, composed by a console, the master, that can control up to three slaves, and a number of disposables (at least one per each slave) that allows driving guide wires and catheters into the human body, separating the doctor from the patient, in order to eliminate ionized radiations for the doctor.

In particular the system is able to provide very fine motion control during angioplasty, using a single slave and a dedicated disposable. But using two slaves in series, it is possible to drive an initial catheter with the slave closer to the patient, and a guide wire even with movable core with the second slave. Each slave can control three parameters, ...

The cranes that are used in hydrotherapy, most of all in swimming pools, are used to move up and down patients with some disabilities. Many of these cranes are hydraulic and maneuvered manually; only a few are semi-automatic and use an electric actuator. The problem is that its use is very rudimentary and not very precise; since it would also be necessary to have two therapists to be able to lower the patient to the pool, which is also very tedious.

One of the best ways to optimize this process and make it easier, safer and more pleasant is using an automatic crane that does the whole process of raising and lowering the patient to the pool. The crane ...

Assessment of OB/GYN patients finds dissatisfaction in common procedures, with “gentleness” as an arguable unit of measure.

Problem: The pelvic exam is of particular note when it is not considered organic due to size, speed, and weight differentials. Additionally, many patients may have grown accustomed to mobility limitations that do not pose significant danger.

Innovation: The newly designed speculum features an additional component that takes the pressure out of the hands of the device operator and places the responsibility on the device itself. It features a ladder-type ribbed locking expansion component and marked units of measure on the shaft.

Marketability:
1. The pelvic exam is not typically considered an instrument of emergency and there would unlikely be a ...

Shape state analysis offers vital insights. Structures change shape before collapsing. Earthquakes are preceded by shifts in relative locations of monitoring stations. Genetic abnormalities can be detected and quantified from locations of anatomical features recognizable to specialists. These and other applications rely on comparing arrays of physical landmarks. Applicable arrays can be in any regular or irregular shape as long as 1) the landmarks reasonably characterize the entity being scrutinized, 2) the representation is uniform for all samples (frames, patients, ...), 3) some minimal degree of consistency holds. In a medical application the second condition requires a complete landmark set for every patient and, though groups can contain all ages/sizes/races ... and substantial abnormalities may be present, the third ...

Shower Belt is the world's first drowning and scalding prevention device for use in the shower. It uses your own body weight to stop the flow of water should you fall. I designed Shower Belt after the sudden and tragic loss of my friend Natalie Fryzak. Natalie succumbed to drowning as a result of an Epileptic seizure while in the bathroom. 50 million people suffer from Epilepsy world wide. With a 20% higher chance of drowning then non-effected people, it is reported 88 people a day will drown in and around the home. You can see this device is long overdue! Shower Belt also protects our elderly. With many aging in place at home retirement is why the assistive ...

Parkinsonism is a group of chronic neurological disorders characterized by progressive loss of motor function resulting from the degeneration of neurons in the area of the brain that controls voluntary movement. All types of Parkinsonism are characterized by four main signs, including tremors of resting muscles, particularly of the hands; muscular rigidity of the arms, legs, and neck; difficulty in initiating movement (bradykinesia); and postural instability. A variety of other features may accompany these characteristics, including a lack of facial expression (known as “masked face”), difficulty in swallowing or speaking, loss of balance, a shuffling gait, depression, and dementia. Peoples who suffer from Parkinsonism cannot drink fluid without any assistance and it is impossible for them to do it ...

The Smart Life Guard Pajamas (SLGP) can be useful in two main cases:

1) In the case of Sudden Cardiac Arrest – A lot of adult people suffer from cardiac problems, which can cause Cardiac Arrest. Because of this reason plenty of people die during sleep, without any chance of medical help.
2) In the case of Sudden Infant Death Syndrome (SIDS) – sudden unexpected death of a child in the age until three years.

Depending on the cases the SLGP can be designed in the needed sizes.

It can be designed with two levels of protection:

1) Heart stop alert – it senses the heart pulse rate and when absence of heart beats is registered – it reacts ...

Torque control
Power assist wheelchairs work best when there is a torque feedback, measuring the user input torque and using it to determine the torque the motor needs to supply to the wheels. But this method has not been able to reach the masses especially in developing countries because torque sensors are comparatively very expensive and are not affordable for customers from below the upper class. Soft-sense uses a new alternative to torque sensors which can be made much cheaper and also allows for other functions. Series elastic actuators are an area of research in robotics that has enabled among other functions, torque control by using a series element with the motor and measuring displacements. Using this in wheelchairs ...
