Abstract: A pipette tip rack system includes a thermoformed clamshell tip container and a dispenser for the clamshell tip container. The tip dispenser includes a base for holding the clamshell container, cover and a lifting mechanism for lifting the lid of the tip container and the cover when a latch on the base is released. The tip dispenser is configured to facilitate one-touch operation so that a laboratory work may hold a pipette in the other hand while using the dispenser, and conveniently open and close the dispenser cover to reduce the risk of contamination. The dispenser can be used without the thermoformed tip container as well.

Abstract: A shaving device comprising a head assembly including a support member having at least one support member magnet and a blade cartridge having at least one face with at least one razor blade and configured to be rotatably coupled to the support member about a pivot axis. The blade cartridge includes at least one blade cartridge magnet having a pole aligned with a pole of the support member magnet to generate a magnetic force that urges the blade cartridge about the pivot axis towards an initial starting position (ISP), wherein the blade cartridge is further configured to rotate about the pivot axis away from the ISP upon application of an external force sufficient to overcome the magnetic force between the support member magnet and the blade cartridge magnet.

Abstract: A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.

Abstract: A transfer device and catheter assembly for the delivery of treatment elements to a selected location within the intraluminal passageways of a patient as part of an intraluminal radiation system. The transfer device includes a gate member that permits the treatment elements to have the transfer device only if the catheter is attached thereto. A pressure indicator provides a visual indication of the fluid pressure within the transfer device, and provides for a release of the fluid if the pressure exceeds a predetermined pressure. The catheter also includes detents to secure it to the transfer device and which must be manually activated to remove the catheter from the transfer device. The transfer device includes circuiting that determines whether the treating elements reside within the transfer device based upon the reflectivity of the treating elements. A method for determining whether treating elements reside in the catheter is also disclosed.

Abstract: Apparatus and method are described for delivery of a treating element, such as a radiation source, through a catheter to a desired site in the intraluminal passageways of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongated flexible catheter tube having proximal and distal end portions, with a lumen extending therebetween, and a diameter sufficiently small for insertion in to a patient's intraluminal passageways. One or more treating elements, such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal end portions under the force of liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

Abstract: This invention is a transfer device and catheter assembly for the delivery of treatment elements to a selected location within the intraluminal passageways of a patient as part of an intraluminal radiation system. The transfer device includes a gate member that permits the treatment elements to leave the transfer device only if the catheter is attached thereto. A pressure indicator provides a visual indication of the fluid pressure within the transfer device, and a pressure relief valve provides for a release of the fluid if the pressure exceeds a predetermined pressure. Transfer device also includes a treatment element detection system, low power indicator, a counter system, and an electromagnetic locking mechanism to prevent the opening or closing of the gate member when less than all of the treatment elements are in the transfer device.
