Methods of forming a gel and related methods of treating subjects with such gels are described. The method may include preparing a composition by combining a macromer comprising a first polyethylene glycol (PEG)-based polymer, a poly(ethylenimine)-based polymer, or a poly(1,2-glycerol) carbonate-based polymer, the macromer including at least one first functional moiety, a crosslinking agent comprising a second PEG-based polymer that includes at least one second functional moiety, and a photoinitiator, and activating the photoinitiator via a light source to form the gel.

Embodiments of the present invention provide a unique new approach to generating operating condition information used for assessing flow assurance and structural integrity. More specifically, apparatuses, systems and sensor housing assemblies configured in accordance with embodiments of the present invention utilize fiber optic sensors for enabling monitoring of operating condition information within one or more elongated tubular members within a subsea environment. To this end, such fiber optic sensors connected by lengths of optical fiber are strategically placed at a plurality of locations along a length of each elongated tubular member thereby allowing critical operating conditions such as strain, temperature and pressure of the elongated tubular member and/or a fluid therein to be monitored. A viscous media is used for mitigating attenuation associated with exposure of optical fiber exposed to forces generated by pressure within the subsea environment.

An intraluminal endoprosthesis such as a stent has a metallic supporting structure and a sleeve surrounding the supporting structure. The sleeve can include fibres which are applied to an outer side of the supporting structure. The fibres each have a polymer core and a hydrogel casing connected thereto. The sleeve can also be formed from a fibre mixture of polymer and hydrogel fibres.

Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product. A polymeric material that includes a SCC polymer may also be fabricated into other medical devices, such as stents.
