Abstract: A cast bioremodelable graft (22) including a cast tubular construct (33) of a bioremodelable substance (34). The bioremodelable substance is cast on or applied to a form and then vacuum pressed to dry or harden the substance. Expandable members (18) are disposed on, in, under or about the cast tubular construct to expand the graft when released from an endoluminal delivery system. A second layer (39) can be applied over the first layer (38) and the expandable stents to contain the stents there between without the need for any separate attachment. The graft is dehydrated and preferably vacuum pressed to harden the bioremodelable substance. The form is removed to form one or more lumens (23-25) in the graft, which is then loaded on an endoluminal delivery system.

Abstract: Disclosed are mammalian tumor and/or cancer cell conditioned substrate preparations having tumor inhibiting activity. In some embodiments, the mammalian tumor and/or cancer cell conditioned substrate preparations are essentially free of cellular components. These preparations comprise a conditioned heterologous acellular collagenous tissue preparation, and may be prepared using a mammalian extracellular matrix substrate. The conditioned substrates include many different anti-tumor and/or anti-cancer biomolecules, such as that population of anti-tumor biomolecules that are secreted and/or produced by mammalian tumor and/or cancer cells as they grow on a substrate, thus imparting the anti-tumor and/or anti-cancer properties to the conditioned substrates of the invention. The present disclosure also provides methods for preparing the mammalian tumor and/or cancer cell conditioned substrates, as well as methods for using the preparations to inhibit tumor growth, such as in a vaccine or wound dressing.

Abstract: Described are methods and systems for testing lumens of cannulated delivery components or assemblies thereof that may be used to deliver cells to a patient. Test cells are contacted with walls of the lumens and/or liquids that contact walls of the lumens, potentially over an incubation period. The test cells are then assessed for an effect of the wall contact, or the liquid contact, on at least one and preferably multiple characteristics of the test cells such as innate immune response, metabolic activity, viability, cytotoxic response, and/or motility. Methods and systems as described can be used in the development and/or manufacture of cannulated delivery devices, for example providing specifications for design or process inputs or outputs, design or process validations, and/or device lot approvals. Also described are devices or products produced in accordance with such methods and systems.

Abstract: Described are medical devices which are or can be used to form tubular medical devices, and related methods. Preferred devices include tubular grafts of biomaterial having lumen walls which present no seam edge that traverses the entire length of the lumen, illustratively including devices having lumen walls which have a discontinuous seam presenting multiple seam edges. Such a device may include a tubular structure formed by inserting a plurality of extensions of a biomaterial sheet through a plurality of corresponding apertures of the sheet.
