    摘要: Implantable materials visible under ultrasound may be delivered to a selected placement site and biodegrade after a certain period of time. Ultrasound visible implantable materials may be delivered through an applicator and may include ultrasound contrast agents and/or radiopaque agents. Applications include monitoring the delivery of an implant of the implantable materials to the placement site with ultrasound and delivery of therapeutic agents to a tissue at the placement site for treating a patient.

    摘要: Methods are provided for making freeze dried hydrogel and structures therefrom that may be introduced into a patient's body for medical applications. Precursor components are combined to initiate crosslinking. The combined precursor components are placed in a chilled tray, and allowed to crosslink to a desired level of complete crosslinking before and/or after being placed onto the tray. The partially crosslinked hydrogel is frozen and freeze dried. After freeze drying, the hydrogel is conditioned to substantially complete crosslinking, and formed into one or more structures, e.g., plugs, hemostatic, or other medical devices. For example, the hydrogel may be cut, machined, rolled, folded, compressed, and/or cored into that may be loaded into delivery devices that may be introduced into a body to implant or otherwise deliver the structures into the body, e.g., to seal a puncture or other passage through tissue.
