Abstract: Embodiments include particle delivery devices and systems and methods of delivering particles to a site. The device and system embodiments include a suspension reservoir which might be a syringe for temporarily storing and delivering a particle suspension. The particle delivery device also includes a mechanical linkage or other structure which allows the suspension reservoir to rotate or otherwise be moved with respect to, or about, a reservoir axis. Rotation or other movement of the suspension reservoir provides a means for maintaining the particles in suspension during particle storage, loading and delivery processes.

Abstract: An implantable prosthesis for repairing a tissue or muscle wall defect. The prosthesis includes a perforated sheet of a biologically compatible material to cover the tissue or muscle wall defect. The perforated sheet has a plurality of perforations extending through the sheet. The perforations may be distributed across the perforated sheet in a non-grid arrangement. The perforations may be non-uniformly distributed across the perforated sheet in groups of perforations arranged in a plurality of concentric circular patterns. Each perforation may be separated from an adjacent perforation by a web of material having a length between adjacent perforations that is a predetermined multiple of the diameter of the perforations.

Abstract: A system and method of automatically creating a window for display on a display device coupled with a user computer are provided. An application server of the system receives search criteria inputted through user interaction at a user computer displaying web pages of a particular website. The system determines that the website may be exited from the user computer. An exit window having information related to the search criteria is launched for display in response to the determination that the website is being exited.
