GLOBO TÉRMICO PARA EL TRATAMIENTO DE LA ESTENOSISTHERMAL BALLOON FOR THE TREATMENT OF STENOSIS
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
Es objeto de la presente invención, tal y como el título de la invención establece, un globo térmico para el tratamiento de la estenosis, preferentemente estenosis arterial no siendo descartable cualquier otro tipo de estenosis.The object of the present invention, as the title of the invention establishes, is a thermal balloon for the treatment of stenosis, preferably arterial stenosis, not ruling out any other type of stenosis.
Caracteriza a la presente invención la especial configuración, diseño y naturaleza de los materiales empleados en el globo que hacen del mismo un globo térmico para el tratamiento de la estenosis.The present invention is characterized by the special configuration, design and nature of the materials used in the balloon that make it a thermal balloon for the treatment of stenosis.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de los globos empleados en cateterismos y en el tratamiento de la estenosis.Therefore, the present invention falls within the scope of balloons used in catheterization and in the treatment of stenosis.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
La estenosis es un estrechamiento anómalo de un conducto u orificio del organismo. Este estrechamiento puede estar presente desde el nacimiento o desarrollarse a lo largo del tiempo debido a la presencia de tumores, engrosamiento o hipertrofia, o por infiltración y fibrosis de las paredes valvulares.Stenosis is an abnormal narrowing of a duct or opening in the body. This narrowing may be present from birth or develop over time due to the presence of tumors, thickening or hypertrophy, or due to infiltration and fibrosis of the valve walls.
Cualquier orificio del cuerpo puede sufrir una estenosis, y puesto que nuestro organismo tiene muchos, hay distintos tipos de estenosis y una gran variedad a la hora de clasificarlas. Algunas de las más comunes son:Any orifice of the body can suffer a stenosis, and since our body has many, there are different types of stenosis and a great variety when it comes to classifying them. Some of the most common are:
• Estenosis vasculares.• Vascular stenosis.
• Estenosis digestivas.• Digestive stenosis.
• Estenosis de la vía aérea. • Airway stenosis.
• Estenosis urológicas.• Urological strictures.
• Estenosis neurológicas.• Neurological stenosis.
La estenosis aórtica se produce cuando la aorta, la principal arteria que lleva sangre fuera del corazón, se estrecha, lo cual disminuye el flujo de la sangre.Aortic stenosis occurs when the aorta, the main artery that carries blood away from the heart, narrows, reducing blood flow.
La consecuencia de esta estenosis es que el corazón deberá trabajar más para bombear la sangre al resto del cuerpo y con el paso del tiempo este esfuerzo puede causar problemas y la debilitación del músculo cardíaco.The consequence of this stenosis is that the heart will have to work harder to pump blood to the rest of the body and over time this effort can cause problems and weakening of the heart muscle.
Las dilataciones coronarias se vienen haciendo con globos cilíndricos que no se ajustan de la manera más conveniente a la reducción progresiva de diámetro que presentan las arterias.Coronary dilations have been performed with cylindrical balloons that do not adjust in the most convenient way to the progressive reduction in diameter of the arteries.
En otras ocasiones se colocan stents, que médicamente hablando no es una solución óptima ya que se puede generar lo que se conoce como "íntima” es decir producir una absorción del stent en el tejido de la arteria, además de no reducir la causa de la estenosis.On other occasions, stents are placed, which medically speaking is not an optimal solution since what is known as "intima" can be generated, that is, the absorption of the stent in the artery tissue, in addition to not reducing the cause of the stenosis.
Por lo tanto, es objeto de la presente invención superar los inconvenientes apuntados de falta de ajuste de los globos cilíndricos y de la falta de conveniencia en el uso de stents, desarrollando unos globos térmicos como los que a continuación se describen y que quedan recogidos en su esencialidad en la reivindicación primera.Therefore, the object of the present invention is to overcome the aforementioned drawbacks of the lack of adjustment of cylindrical balloons and the lack of convenience in the use of stents, developing thermal balloons such as those described below and which are included in its essentiality in the first claim.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
Es objeto de la presente invención un globo térmico que transmite la temperatura.The object of the present invention is a thermal balloon that transmits temperature.
La estenosis de las arterias coronarias se produce por la acumulación y crecimiento de células en las paredes de las arterias coronarias ya que engordan con el colesterol que viene del flujo de sangre fresca. Coronary artery stenosis is caused by the accumulation and growth of cells in the walls of the coronary arteries as they are fattened by the cholesterol that comes from the fresh blood flow.
El tratamiento térmico de choque busca que las células cambien su posición o dirección evitando que engorden del colesterol de la sangre fresca, haciendo que dicho tratamiento reduzca la masa de células acumuladas en una arteria.The shock heat treatment seeks to make the cells change their position or direction, preventing them from fattening up from the cholesterol in the fresh blood, causing said treatment to reduce the mass of cells accumulated in an artery.
El tratamiento térmico puede ser por temperaturas altas de hasta 70°C o por temperaturas bajas del orden de 10°C como es el caso de las personas diabéticas que ya de por sí tienen una temperatura corporal más elevada que el resto.Heat treatment can be by high temperatures of up to 70°C or by low temperatures of the order of 10°C, as is the case of diabetics who already have a higher body temperature than the rest.
El Globo térmico para el tratamiento de la estenosis objeto de la invención tiene una forma alargada y cuenta con una pared exterior hecha de un material que comprende Poliamida, donde la pared exterior tiene un espesor inferior a 15 milésimas y dentro del globo hay un canal para recibir un fluido que infla el globo.The thermal balloon for the treatment of stenosis object of the invention has an elongated shape and has an outer wall made of a material that comprises Polyamide, where the outer wall has a thickness of less than 15 thousandths and inside the balloon there is a channel for receive a fluid that inflates the balloon.
De forma preferente, pero no limitativa, la poliamida es Nylon y el espesor de la pared es de entre 8 a 10 milésimas de espesor.Preferably, but not limiting, the polyamide is Nylon and the thickness of the wall is between 8 to 10 thousandths thick.
Para poder aplicar el tratamiento térmico sobre las paredes de las arterias donde se presenta la estenosis se hace necesario que el balón presente unas determinadas características, y fundamentalmente, estar realizado en Nylon que no se deforma hasta los 100°C con una pared de entre 8 a 10 milésimas frente a las 20 milésimas que presentan las paredes de los globos del estado de la técnica.In order to apply the heat treatment on the walls of the arteries where the stenosis occurs, it is necessary for the balloon to have certain characteristics, and fundamentally, to be made of Nylon that does not deform up to 100°C with a wall between 8 to 10 thousandths compared to the 20 thousandths that the walls of the balloons of the state of the art present.
Gracias a la naturaleza y espesor del balón cuando se aplica un fluido caliente la temperatura se transmite rápidamente hacia las paredes donde está ubicado el globo.Thanks to the nature and thickness of the balloon, when a hot fluid is applied, the temperature is quickly transmitted to the walls where the balloon is located.
Además, y de forma complementaria para poder lograr un mejor avance y ajuste del globo en las paredes arteriales, éste puede presentar una configuración cónica donde el extremo distal presenta una reducción de diámetro frente al extremo proximal.In addition, and in a complementary way to be able to achieve a better advancement and adjustment of the balloon in the arterial walls, it can present a conical configuration where the distal end has a reduction in diameter compared to the proximal end.
