EXPANDABLE SHEATH FOR INTRODUCING AN ENDOVASCULAR DELIVERY DEVICE IN TO A BODY

Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the del...

description Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a variable diameter inner liner wound in a spiral slidable configuration and an outer layer. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath. Los aspectos de una vaina expansible se pueden usar junto con un conjunto de catéter para introducir un dispositivo protésico, tal como una válvula cardíaca, en un paciente. Dichos aspectos pueden minimizar el traumatismo en el vaso al permitir la expansión temporal de una parte de la vaina introductora para acomodar el aparato de entrega, seguido de un retorno al diámetro original una vez que pasa el dispositivo protésico. Algunos aspectos pueden incluir una vaina con un revestimiento interior de diámetro variable enrollado en una configuración deslizante en espiral y una capa exterior. La vaina descrita está configurada para expandirse desde un diámetro en reposo predeterminado dr hasta un diámetro expandido de durante la aplicación de una fuerza radial hacia el exterior mediante el paso de un dispositivo médico a través de la vaina
