Provided is an organic electrolytic solution including a lithium salt and an organic solvent containing an alkoxy-containing compound such as 1,1,3-trimethoxypropane. Each anchor member having an elongate first and second beams. This invention can be practiced by referring to the published mutation patterns for known anti-HIV drugs, or by determining the mutation pattern for a new drug. A first variant of the rod is almost completely formed by a metal foam, whereas a second embodiment comprises merely a core made of the metal foam with a relatively small diameter, which core is surrounded coaxially by a support casing and an outer sleeve. The suturing device can have an expandable area at its distal end that can expand its diameter to between approximately 10 mm and 150 mm. Preferred is a bow shaped barrel with an arched and hinged or flexible upper member and a rigid lower member.
