    Abstract: A surface coating composition for providing a self-assembling monolayer, in stable form, on a material surface or at a suitable interface, as well as a method of preparing such a composition and a method of using such a composition to coat a surface, such as the surface of an implantable medical device, in order to provide the surface with desirable properties. The method provides the covalent attachment of a SAM to a surface in a manner that substantially retains or improves the characteristics and/or performance of both the SAM and the surface itself. Covalent attachment is accomplished by the use of one or more latent reactive groups, e.g., provided by either the surface and/or by the SAM-forming molecules themselves.

    Abstract: A crosslinkable macromer system and related methods of preparing the system and using the system in the form of a crosslinked matrix between a tissue site and an implant article such as a tissue implant or on the porous surface of a prosthetic device. The macromer system includes two or more polymer-pendent polymerizable groups and one or more initiator groups (e.g., polymer-pendent initiator groups). The polymerizable groups and the initiator group(s), when polymer-pendent, can be pendent on the same or different polymeric backbones. The macromer system provides advantages over the use of polymerizable macromers and separate, low molecular weight initiators, including advantages with respect to such properties as nontoxicity, efficiency, and solubility. A macromer system of the invention can be used as an interface between the tissue site and implant article in a manner sufficient to permit tissue growth through the corsslinked matrix and between the tissue site and implant. In a preferred embodiment, polymers with pendent polymerizable groups, for use in the macromer system, are prepared by reacting a polysaccharide polymer with a reactive moiety in an organic, polar solvent such as formamide.

    Abstract: A reagent composition adapted to be coated onto a support surface in order to provide that surface with a high density of reactive groups. The surface, thus coated, can be used for any suitable purpose, and is particularly well suited for use as a solid phase synthesis support surface. The synthesis support surface, in turn, can be used in repetitive and combinatorial syntheses such as the synthesis of polynucleotides, polypeptides and polysaccharides. The polymeric coating can be used to provide increased effective surface area, particularly in situations in which the effective area of the support surface is itself limited, as on the surface of a silicon wafer. In so doing, the polymeric coating provides an optimal combination of such properties as reactive density and surface area or volume.

    Abstract: An anchored dilator includes a push tube having proximal and distal push tube portions. A dilator tip is coupled with the distal push tube portion and is configured for selectable coupling with a catheter. The dilator tip includes an anchor cuff having a cuff interface. The anchor cuff is configured to transition between a shuttle configuration having a shuttle profile and an anchored configuration having an anchored profile larger than the shuttle profile. A cuff operator assembly is configured to transition the anchor cuff between the anchored and shuttle configurations. The cuff operator assembly includes a cuff operator movably coupled with the dilator tip, and an operator shaft coupled with the cuff operator. The operator shaft extends toward the proximal push tube portion. Actuation of the cuff operator with the operator shaft transitions the anchor cuff between the shuttle configuration and the anchored configuration.
