Abstract: The invention relates to a lighting device (100), which is equipped for fastening to a surgical instrument (200) or, by means of adapter (90; 91), to a body part (92), in particular a finger of a surgeon or of an operating room assistant, in order to serve as a light source during a surgical operation, in particular within a body cavity or organ cavity of genuine or traumatic origin and in other body regions that are difficult to access. At least one pin (20) pointing outward from the wall of the housing (10) is arranged on the housing (10) of the lighting device (100) in a wall area (30) directed toward the surgical instrument in the fastening position, which pin has a light emitting opening (40) at the distal end of the pin and is designed for passing through an opening (220) of the surgical instrument or of the adapter (90; 91) and thus establishing a form-closed or force-closed connection to the opening. The pin (20) is preferably movable in order to achieve optimal illumination of the operation site.

Abstract: The invention relates to a vessel connector (10) for surgically connecting two vessels and/or prosthetics to each other, comprising a sleeve-shaped body (1), the walls of which are designed to be elastic, such that the force acting on the ligature or suture is limited to the extent that no pressure points or necroses occur in the vessel. It is made of two substantially rigid outer rings (2), delimiting the sleeve-shaped body, and webs (3) present between the rings, wherein at least regions of individual webs have a shape (4) deviating from a straight line over longer distances, and it has at least one ring-shaped region (5) of higher elasticity between the rigid rings. The connector provides a blood-tight connection of at least two natural or artificial vessels, including prosthetic connections, a prosthesis to a natural vessel, or two prostheses to each other.

Abstract: For an implantable device intended for use in the human body an in-vivo colonization with autologous cells is often desired. The devices, especially prosthetic devices like implant tissues, grafts, shunts, vessels, organs or a part of organs are commonly derived from animal or human origin and comprise a collagen-based tissue matrix. The invention proposes a coating deposited on a surface of the device and comprising the matrix protein CCN1 as an extracellular matrix-associated protein mediating cell adhesion or cell migration.
