Assignee:

Lam Research Corporation - Fremont CA

International Classification:

G01R 31/26

US Classification:

324765

Abstract:

A method of determining an average electrical response to a conductive layer on a set of substrates vibrating about a vibration mean is disclosed. The method includes positioning a sensor near a position on a first substrate; and measuring a first plurality of electrical responses, wherein each of the first plurality of electrical responses is function of an electrical film property response and a first substrate proximity response. The method also includes positioning the sensor near the position on a second substrate; and measuring a second plurality of electrical responses, wherein each of the second plurality of electrical responses is function of the electrical film property response and a second substrate proximity response. The method further includes determining a first average electrical response for the first substrate and a second average electrical response for the second substrate, wherein a difference between an average first substrate proximity response and an average second substrate proximity response is about zero.

Assignee:

Abbott Laboratories - Santa Clara CA

International Classification:

A61M 25/00

US Classification:

427 228, 427 21, 118305, 118320

Abstract:

System and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and an applicator positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A positioning device maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by ejecting a pressurized medium against the surface of the expandable member.

Assignee:

ABBOTT CARDIOVASCULAR SYSTEMS, INC. - Santa Clara CA

International Classification:

A61M 5/14

US Classification:

604508

Abstract:

Methods for more uniformly delivering drugs or other treatment agents locally to the vasculature of a mammal are disclosed. These methods use one or more strategies to facilitate rapid mixing with the blood flowing past a device or otherwise improve the uniformity of drug delivery. Some of these strategies employ medical devices with diffusion members.

US Classification:

427 21, 118300

Abstract:

A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet.

US Classification:

424422, 427 23

Abstract:

Method of coating an expandable member, e.g. balloon, is provided, the method comprising providing an expandable member having an outer surface. The method includes a plasma treatment with a supply of gas performed on at least a portion of the outer surface of the expandable member. A therapeutic agent is applied on at least the plasma treated portion of the outer surface of the expandable member after the plasma treatment is performed. The plasma treatment can reduce the adhesion of therapeutic agent to the surface of the expandable member. A medical device made by the disclosed method is also provided.

A61M 25/10

US Classification:

604509, 604104

Abstract:

Method of delivering a therapeutic agent includes delivering at least a portion of a medical device within a vasculature. The medical device includes a tubular member having a proximal end and distal end defining a longitudinal axis therebetween, an expandable member proximate the distal end of the tubular member, a tissue engaging member proximate the expandable member, a sheath disposed over the tissue engaging member, and a therapeutic agent disposed on at least the expandable member or the tissue engaging member. The method further includes deploying the tissue engaging member at a select location by displacement of the sheath relative the tissue engaging member, inflating the expandable member to engage the therapeutic agent with a vessel wall, deflating the expandable member, and withdrawing the medical device from the vasculature.
