摘要: A medical article having a metal or glass surface with the surface having an adherent coating of improved biocompatibility. The coating is made by first applying to the surface an silane compound having a pendant vinyl functionality such that the silane adheres to the surface and then, in a separate step, forming a graft polymer on the surface with applied vinylsilane such that the pendant vinyl functionality of the vinylsilane is incorporated into the graft polymer by covalent bonding with the polymer. Biomolecules may then be covalently attached to the base layer.

摘要: An improved spacer material for improving the biocompatibility of a biomaterial and a method for making it in which a polyalkylimine is covalently attached to an aminated substrate and combined with a crosslinking agent which is at least difunctional in aldehyde groups. The polyalkylimine can be, for example, polyethyleneimine and the crosslinking agent can be, for example, glutaraldehyde. Preferably, the crosslinking agent is applied in dilute solution and at a pH suitable to accomplish light crosslinking of the polyalkyaimine and also provide aldehyde linkages at the interface between the biomolecule and the spacer.

摘要: An improved spacer material for improving the biocompatibility of a biomaterial and a method for making it in which a polyalkylimine is covalently attached to an aminated substrate and combined with a crosslinking agent which is at least difunctional in aldehyde groups. The polyalkylizine can be, for example, polyethyleneimine and the crosslinking agent can be, for example, glutaraldehyde. Preferably, the crosslinking agent is applied in dilute solution and at a pH suitable to accomplish light crosslinking of the polyalkylimine and also provide aldehyde linkages at the interface between the biomolecule and the spacer.

摘要: To minimize the incidence and consequences of device related infection that occur after prosthetics implants of neuro-muscular stimulating devices, an infection resistant intra-muscular lead has been developed and is disclosed herein. Infection incidence has been decreased by using biomaterials able to release antibacterial drugs (gentamicin) at a controlled rate for the first 3-6 weeks after implant.

摘要: A combination ion sensing and reference electrode and a method for producing it. The electrode is formed of bi-lumen plastic tubing using one lumen as sensing chamber and the other as a reference chamber. A portion of the sensing chamber extends distally relative to the reference chamber, and is permeated with an ion selective material by soaking that portion in a solution containing the ion selective material. The method of manufacture is thereby simplified and sealing of the chambers is improved.
