  • Publication number: 20240207033
    Abstract: A method of manufacturing a therapeutic device includes providing a member that defines first pores having a first average size that (i) allows passage of a therapeutic agent through the first pores and (ii) prevents passage of immune cells through the first pores. The method further includes spinning the member about an axis of the member and applying a fibrous material to the member while the member spins to form a coating that surrounds the member. The coating defines second pores having a second average size that is larger than the first average size, and the second pores are sized to promote vascularization along the coating. The member and the coating together form a container of the therapeutic device, and the container defines an interior region for accommodating a plurality of cells capable of producing the therapeutic agent.

  • Publication number: 20240207588
    Abstract: A method of manufacturing a therapeutic device includes forming a container wall that is sized to contain multiple cells capable of producing a therapeutic agent within an interior region of the container wall. The method further includes exposing the container wall to a solvent to remove material from the container wall to define first pores along an interior portion of the container wall and second pores along an exterior portion of the container wall. The first pores have a first average size that (i) allows passage of the therapeutic agent through the first pores and (ii) prevents passage of immune cells through the first pores. The second pores have a second average size that is larger than the first average size, and the second pores are sized to promote vascularization along the exterior portion.

  • Publication number: 20240197959
    Abstract: An implantable device for providing a therapeutic agent includes a container configured to contain multiple cells capable of producing the therapeutic agent within an interior region of the container and a substance capable of reacting to generate oxygen for the multiple cells within the interior region of the container. The container defines first pores defined by an interior wall portion of the container and second pores defined by an exterior wall portion of the container. The first pores have a first average size that (i) allows passage of the therapeutic agent through the first pores and (ii) prevents passage of immune cells through the first pores. The second pores have a second average size that is larger than the first average size, and the second pores are sized to promote vascularization along the exterior wall portion.
