Organosilicon compounds having organooxysilyl groups at ends and a polysulfide group at an intermediate of the molecule, which are linked through a divalent hydrocarbon group containing a monosulfide or polysulfide group are novel. Each cutting blade of each cutting strip has a portion staggered with respect to an adjacent cutting blade of an adjacent cutting strip along a circumferential direction around the longitudinal axis, and a remaining portion aligned with the adjacent cutting blade of the adjacent cutting strip along the circumferential direction. A method for relieving pain by topical application of the composition is also provided. Embodiments are disclosed which include vapor-permeable portions which facilitate lyophilization of materials in situ. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter.
