427 21

Abstract:

Methods for applying an antimicrobial coating to a medical device is disclosed. Generally, the methods comprise providing a medical device, dispensing an antimicrobial coating onto the device, flushing excess coating from the device, and curing the coating onto the device. In one aspect, the coating includes a UV-curable, antimicrobial composition. In this aspect, the medical device can be coated and the coating can be cured with UV light in a manner of seconds. In another aspect, the coating includes an antimicrobial solution that contains an acrylate-type polymer or copolymer. In this aspect, the medical device can be coated and the coating can be heat-cured in a manner of minutes. Both the UV-curable composition and the antimicrobial solution can also include rheological modifiers, as necessary. Additionally, the compositions include one or more antimicrobial agents, which may be selected from a wide array of agents.

Assignee:

Becton, Dickinson And Company - Franklin Lakes NJ

International Classification:

A61M 25/02

US Classification:

60416404, 604180

Abstract:

Intravenous catheter devices are provided which may include one or more adhesive portions which are positioned and configured to temporarily maintain a position of a catheter assembly following catheterization. A release liner covering and protecting the adhesive portions may be automatically removed to reveal the adhesive upon withdrawal of an introducer needle of the catheter assembly. The adhesive may be configured such that a clinician may insert the catheter assembly into the patient, adjust the catheter adapter of the catheter assembly to a desired position, withdraw the introducer needle, thereby removing a protective, non-adhesive release liner from the adhesive of the positioned catheter assembly, thereby temporarily fixing the position of the catheter assembly at the desired position by contacting the exposed adhesive to the skin of the patient.

International Classification:

A61M 25/02

US Classification:

604180

Abstract:

Sterile intravenous catheter securements and securement dressings that provide simpler, more effective, and lower risk intravenous catheter placement and securement in a patient are described. Catheter securement dressings may include one or more adhesive portions positioned and configured to maintain a position of a catheter assembly following catheterization. Catheter securement dressings may be secured to a patient with an adhesive portion, and the catheter assembly may then be placed into the patient through an access opening in the catheter securement dressing. Portions of catheter securement dressings may then by folded over and adhered to each other and portions of the catheter assembly to secure the catheter assembly to the patient.

International Classification:

B05D 302
B05D 508
C07F 902

US Classification:

427 23

Abstract:

The lubricant of this invention is lecithin. The lubricant is applied to the surface to be lubricated by forming a colloidal solution of water and lecithin. This solution may also include a surfactant, Vitamin E or its derivative. In addition, a solution stabilizer and an antimicrobial agent may be used to clarify the solution and to inhibit microbial growth in the solution.

Assignee:

Becton Dickinson and Company - Franklin Lakes NJ

International Classification:

C10M15502
A61M 2500

US Classification:

508208

Abstract:

This invention relates to a new water soluble lubricant for a medical device, such as a catheter and an introducer needle. The lubricant is a silicone based water soluble compound. Preferably, a silicone surfactant is used such as a block copolymer polyalkylene oxide-modified polydimethylsiloxane. Alternatively, an alkylene oxide modified silicone glycol may be used as the lubricant. In addition, lecithin can be added as a lubricant. The lubrication solution includes a solution stabilizer to clarify the solution and antimicrobial agents to inhibit microbial growth in the water solution or on the coated product. Vitamin E or its derivatives may also be used in the lubrication solution.

US Classification:

508208

Abstract:

The two part tipping lubricant of this invention comprises water as the solvent. The lubricant is a silicone surfactant, which is non-ionic and which is a good lubricating fluid. No separate surfactant or lubricant is needed. The lubricant solution into which the catheter is dipped may also include low percentages of a solution stabilizer and an antimicrobial agent to clarify the solution and to inhibit microbial growth in the water solution. Vitamin E or its derivative may also be used in the lubrication solution to prevent degradation of the solution.

Abstract:

This invention relates to a process of making a shaped tip on a catheter. In this process, a lubricant solution is placed on a catheter, the catheter is placed on a mandrel, the catheter is heated, and the mandrel is engaged with a die to form a shaped tip on the catheter. The tipping lubricant of this invention comprises water as the solvent. The lubricant is a silicone surfactant, which is non-ionic and which is a good lubricating fluid. The lubricant solution into which the catheter is dipped includes low percentages of a solution stabilizer and an antimicrobial agent to clarify the solution and to inhibit microbial growth in the water solution. Vitamin E or its derivative may also be used in the lubrication solution.
