Description
Catéter con balón con endoprótesis no
desplegable.
Cuando un balón utilizado para angioplastia
transluminal percutánea (PTA, percutaneous transluminal angioplasty)
o para angioplastia coronaria transluminal percutánea (PCTA,
percutaneous transluminal coronary angioplasty) es inflado y
forzado a contactar con la placa, el balón puede tener tendencia a
moverse o deslizarse longitudinalmente respecto de la lesión o la
pared del vaso sometidos a tratamiento.
Los balones cortantes (aterotomía) han
demostrado recientemente su eficacia clínica para prevenir la
reincidencia de algunos tipos de reestenosis (específicamente
lesiones calcificadas y reestenosis intrastent). El balón cortante
es un catéter de dilatación coronaria con 3 o 4 aterotomos
(cuchillas microquirúrgicas) adheridos longitudinalmente a la
superficie del balón. Cuando el balón cortante se infla los
aterotomos se mueven radialmente y abren la arteria ocluida,
mediante la acción de realizar una incisión en la placa arterial y
comprimirla de forma controlada. Una ventaja adicional del balón
cortante es que mantiene su posición durante el inflamiento,
mediante el uso de las cuchillas de metal sobre la superficie
externa del balón que penetran en el tejido e impiden que el balón
se mueva.
Por consiguiente, el objetivo principal de la
presente invención es proporcionar un balón para PTA o PCTA que,
como un balón cortante, tenga un reducido potencial de deslizamiento
cuando se infla en un vaso. El documento W0 9805377 revela un
catéter con balón que tiene una malla para su expansión dentro de la
cavidad de un vaso sanguíneo, malla que está fabricada a base de un
material con memoria.

\vskip1.000000\baselineskip
La endoprótesis (stent) no desplegable de la
presente invención está definida en la reivindicación 1. Puede
utilizarse en conjunción con un catéter con balón convencional. Un
catéter para PTA o PTCA (catéter de dilatación) puede ser un
catéter coaxial con elementos internos y externos, que comprenden
respectivamente una cavidad de cable guía y una cavidad de
inflamiento del balón. Cada elemento puede tener hasta 3 capas y
estar reforzado con trenzados. El extremo proximal del catéter
tiene un núcleo de Luer para conectar un medio de inflamiento, y un
medio de relajación de tensión se extiende en dirección distal una
distancia corta desde el núcleo de Luer. Los extremos distales de
los elementos externo e interno pueden incluir una conicidad. El eje
del catéter se construye utilizando materiales y procesos
convencionales. También es posible un catéter que tenga una
canalización multi-durómetro con tecnología de
rigidez variable. El catéter debería ser compatible con un catéter
guía 6F. Opcionalmente el catéter puede ser de diseño
multi-cavidad.
El balón 1 puede estar fabricado de nailon, de
copolímero de nailon (elástico, no perforado) o de PET (alta
presión, no elástico) con un recubrimiento de uretano para
proporcionar pegajosidad. El balón puede ser un balón de múltiples
capas, que van desde una capa interna no elástica hasta una capa
externa que es la más elástica. Por ejemplo una capa más interna de
PET que proporciona un balón de presión superior, rodeada por una
capa externa de nailon que proporciona una superficie más resistente
a perforaciones. El balón puede tener un diámetro en el rango de
1,5 a 12 mm (1,5 a 4 mm para vasos coronarios y 4 a 12 mm para vasos
periféricos) y de 15 a 60 mm de longitud (15 a 40 mm para vasos
coronarios y hasta 60 mm para vasos periféricos). La presión de
inflamiento del balón estará en el rango de 8 a 20 atmósferas, en
función del grosor de la pared del balón. Una vez inflado, los
extremos o cuellos del balón tienen forma de cono.
De acuerdo con la invención, el balón está
previsto con una estructura de Nitinol (NiTi) en general designada
como 2, que incorpora pliegues para la expansión tanto radial como
longitudinal de la estructura 2 de Nitinol en respuesta a la
expansión longitudinal y radial del balón durante el inflamiento, de
modo que la estructura de Nitinol 2 mantiene el balón en su
posición prevista durante el inflamiento. Esta estructura de Nitinol
2 puede describirse como una endoprótesis no desplegable o
provisional, que sirve tanto para la rotura controlada de la
oclusión del vaso como para sujetar la pared del vaso durante un
procedimiento de angioplastia. La estructura 2 de Nitinol comprende
un hipotubo de corte por láser, que se expande tras el inflamiento
del balón pero se pliega tras el desinflamiento del balón debido a
las propiedades super-elásticas del material de
Nitinol, en lugar de permanecer expandido en la condición
desplegada como harían en general las endoprótesis.
La estructura de Nitinol o endoprótesis no
desplegable 2 tiene un extremo proximal 3 y un extremo distal 4 y,
en alguna posición entre ambos, de 3 a 12 tirantes o cables 5 (en
función del tamaño del balón - pero con mayor probabilidad de 3 o 4
tirantes) con un patrón de pliegues radiales y longitudinales. Es
bien conocido el uso del corte por láser en relación con la
fabricación de endoprótesis (por ejemplo véase la Patente de EE.UU.
Número 5 994 667, de Meridan y otros), como lo es el uso de la
aleación super-elástica de níquel y titanio
denominada Nitinol (por ejemplo, véase la Patente de EE.UU. Número 6
312 459, de Huang y otros).
Como se ve en la realización de las figuras 1 a
4, cada extremo de los cuatro tirantes 5 tiene un pliegue
sinusoidal 6 que permite que el hipotubo de corte por láser se
expanda longitudinalmente cuando se infla el balón 1. La longitud
lineal de los pliegues sinusoidales 6 está dimensionada para
acomodar la expansión longitudinal del balón 1 debida al
inflamiento. La forma en sección transversal del tirante o cable 5
puede ser redonda, triangular o rectangular. El diámetro preferido
de los tirantes 5 varía desde 0,08 mm a 0,25 mm.
En el centro longitudinal del hipotubo, un
conector circunferencial 7 con forma de U une cada tirante 5 con su
tirante adyacente. Como se ve mejor en las figuras 3 y 4, los
conectores 7 con forma de U están en lados opuestos del eje radial
central. El extremo distal 4 del hipotubo está adherido al cuello
distal del balón o al extremo distal del eje del catéter, y el
extremo proximal 3 del hipotubo está unido al cuello proximal del
balón o bien al extremo proximal del eje del catéter. Los tirantes 5
pueden estar sujetos a la región operativa del balón 1 para ayudar
al hipotubo a permanecer con el balón cuando este se infla y se
desinfla, y puede utilizarse un adhesivo tal como adhesivo de
cianoacrilato para fijar en varios puntos los tirantes sobre el
balón.
Los ejes de catéter a los que se unen el balón y
el hipotubo de corte por láser, pueden tener diámetros que oscilan
entre 2,5 F y 8 F, y el extremo distal puede ser cónico y de
diámetro ligeramente menor que el extremo proximal.
En la figura 6, las dimensiones del hipotubo de
corte por láser son para utilizarlo con un balón de 3 mm (0,118
pulgadas) de diámetro por 20 mm de longitud. La circunferencia de un
balón de 3 mm es \Pi * D = 3,14 * (3 mm) = 9,42 mm o 0,37
pulgadas. Como puede apreciarse fácilmente, la longitud total de
todos los conectores (superiores y posteriores) 7 con forma de U
debe ser mayor que la circunferencia del balón inflado 1. La
longitud de cada conector 7 con forma de U (superior y posterior)
puede calcularse utilizando la siguiente ecuación:
\frac{\Pi\cdot
d}{n},
donde d es el diámetro del balón
inflado y n es el número de tirantes. La longitud total de los
pliegues con forma de U (superior y posterior) debe exceder esta
longitud.
El número resultante se divide por 2 para
obtener la longitud que debería exceder cada lado
superior-y-posterior del conector
con forma de U. Por ejemplo: para un hipotubo de corte por láser con
cuatro tirantes, compatible con un balón de 3 mm, la longitud de
cada conector (superior y posterior) con forma de U es de 9,40 mm
(0,37 pulgadas) dividido por 4 = 2,35 mm (0,0925 pulgadas).
Dividiendo otra vez por 2 se obtiene 1,17 mm (0,04625 pulgadas).
Esta es la longitud que debe exceder cada lado del conector con
forma de U.
\newpage
Además hay uno o más conjuntos de conectores 7
con forma de U entre los pliegues sinusoidales 6. El conjunto
incluye un conector con forma de U para cada tirante (3 tirantes -
un conjunto de 3 conectores con forma de U; 4 tirantes - un
conjunto de 4 conectores con forma de U; y así sucesivamente). El
número de conjuntos de conectores con forma de U depende de la
longitud del balón y, por lo tanto, de la longitud del hipotubo de
corte por láser. Para un balón de 20 mm de longitud hay un conjunto
de conectores con forma de U separados 10 mm desde el extremo (en
el punto a medio camino a lo largo de la longitud del balón). Para
un balón de 40 mm de longitud hay tres conjuntos de conectores con
forma de U separados en incrementos de 10 mm (el primer conjunto
está separado 10 mm respecto de un extremo; el segundo conjunto está
separado 10 mm respecto del primer conjunto; y el tercer conjunto
está separado 10 mm tanto respecto del segundo conjunto como
respecto del otro extremo). La ecuación para el número de conjuntos
de conectores con forma de U es
\frac{L}{10} -
1,
donde L = longitud del balón en mm.
Otras realizaciones tales como las mostradas en las figuras 7 y 8,
no incorporan los conectores intermedios con forma de
U.
