TEMPORARY CATHETER FOR BIOPSY SITE TISSUE FIXATION

摘要

Devices and methods are provided for temporarily maintaining access to a body cavity in a targeted tissue region within a patient's body. A catheter for temporarily at least partially filing a body cavity in a targeted tissue region within a patient's body includes a shaft having a distal end, a proximal end, and a cavity filling member on a distal shaft section configured to at least partially fill the body cavity. A proximal shaft section is configured to be folded so as to be subcutaneously deployed within the patient when the cavity filling member is disposed within the body cavity so as to prevent intrusion of bacteria. An anti-bacterial material is applied to or incorporated within a surface of the shaft and the cavity filling member so as to prevent bacteria growth.
