  • Publication number: 20090112064
    Abstract: A non-invasive device for lubricating and facilitating the insertion and removal of an endoscope into a body cavity. In one embodiment, the device consists of an annular outer tube having an inner diameter sized to permit sliding of an endoscope there through. The outer surface of the outer tube may be suitably textured for improved gripping. A reservoir is positioned on the outer tube and may be compressed to discharge lubricating fluid on a passing endoscope. The tube surface is textured to enhance control and ergonomics and is flexible to allow manipulation, removal and placement. A flange may be positioned at the proximal end of the tube to provide a barrier to movement of excess lubricant onto the central portion of the tube. The invention also comprises the use of a reservoir for lubricants to be applied to the endoscope as it passes through the device and the enhanced control by way of a threaded internal pattern that engages an endoscope outer surface.

The catheter assembly has a hydrophilic coating applied to at least a portion of the outer surface of a catheter tube or shaft which may be surrounded by a sleeve to provide a no-touch, sure grip feature. The catheter assembly is disposed within the catheter receiving cavity of the package together with a limited amount of a vapor donating liquid provided as a source of vapor to activate the hydrophilic coating. The amount of vapor donating liquid is less than the amount that would otherwise be sufficient to cause a spill hazard. It may be loose liquid as a desired percentage of the volume of a tube-receiving portion of the catheter receiving cavity of the package, or it may be contained in a liquid sequestering element.

  • Patent number: 7365126
    Abstract: A shaped medical device article prepared from a polymer melt composition comprising a polymer ester, a transesterification catalyst, and a tri- or tetraalkoxy silane, by forming and solidifying said composition, and after solidification, subjecting the composition to reaction conditions to effect hydrolysis at least some alkoxysilyl groups remaining in the composition to form silanol groups and to effect condensation of said silanol groups to form a ceramic network. The polymer ester may be a vinyl ester homopolymer or copolymer, or a polymer having ester groups in the backbone thereof.

  • Publication number: 20080086096
    Abstract: Described is a catheter which includes a reinforced polymer shaft. The polymer includes nano particles having a dimension of less than about 6 nm. Described is also a method of forming a medical device. Granules of a selected polymer are prepared. Reinforced granules of the selected polymer are prepared. The reinforced granules include nano particles. The granules and the reinforced granules are then mixed in a ratio selected to obtain a desired concentration of the nano particles. The granules and the reinforced granules are extruded to form a substantially tubular element.

  • Publication number: 20080051736
    Abstract: According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.

  • Patent number: 7331940
    Abstract: A percutaneous access device is provided including a sleeve having an inner lumen extending therethrough that is adapted to slidably receive a catheter, and at least one flange disposed around the sleeve and adapted to be positioned adjacent a tissue surface. In a preferred embodiment, the device includes a first flange disposed around the sleeve and adapted to be positioned adjacent a first tissue surface, and a second flange disposed around the sleeve and spaced apart from the first flange such that the second flange is adapted to be disposed adjacent a second tissue surface opposed to the first tissue surface. In use, the flanges 16, 18 are positioned on opposed sides of tissue so that the device 10 is effective to prevent tissue surrounding the percutaneous access device from coming into contact with the catheter as it is introduced through the sleeve 12.
