A balloon implantation kit includes an inflatable biodegradable balloon configured to be implanted in a human body and a hydrogel composition. In some cases, the hydrogel composition is provided in a container configured to be introduced into the biodegradable balloon. For some applications, the biodegradable balloon includes a joint spacer for treatment of a joint of a human subject, such as a subacromial spacer, a glenohumeral spacer, or a spacer for another joint, such as a knee, hip, ankle, or hand (e.g., CMC1) joint. In these applications, the biodegradable balloon is configured to be inserted into a space of a joint of the human body, and is shaped to provide mechanical support to the joint until the biodegradable balloon resorbs into the human body. For other applications, the biodegradable balloon includes a soft tissue spacer.

Methods of making sleeved hydrophilic urinary catheters.

The purpose of the present invention is to provide a viscoelastic composition having excellent operability, which is suitable for use in securing the field of view of an endoscope when opaque dark-colored liquid accumulates inside a canal and obstructs the field of view of the endoscope, the viscoelastic composition securing the field of view by pushing the liquid aside, and to provide a method for securing the field of view of an endoscope using the viscoelastic composition. The viscoelastic composition for securing the field of view of an endoscope comprises a substance having viscoelastic properties and water, preferably has a hardness of 550 N/m.sup.2 or less, a viscosity (25 C.) of 200 to 2,000 mPa.Math.s, and a loss tangent of 0.6 or less, and more preferably has an electrical conductivity of 250 S/cm or less. The method for securing the field of view of an endoscope comprises feeding the viscoelastic composition from a proximal part of the endoscope, through a channel, into a distal part of the endoscope.

Multifunctional crosslinkers are a reaction product between a polyaziridine compound and two or more functionalized benzophenones. The polyaziridine compound is linked to the functionalized benzophenones through two or more reacted aziridine groups. Coating compositions, comprising: a polymer, and multifunctional crosslinkers. Coated medical devices, comprise a lubricious coating bonded adjacent to an exterior surface of the medical device. The lubricious coating is prepared by UV-curing a coating composition, wherein the coating composition comprises: a water/isopropyl alcohol (IPA) soluble polymer and/or a UV-curable polymer, and a water/IPA soluble multifunctional crosslinker.

A medical device for insertion into a natural or artificial body opening, such as a urinary catheter is described. The medical device comprises a substrate having a wall enclosing an internal cavity that forms a tubular body. The wall extends between a proximal insertion end and a distal rearward end. The wall comprises at least 30 wt % of natural fibers, such as cellulose fibers. One example medical device is, at least to a large extent, made of paper.
