Patent number: 8021630Abstract: An anticoagulant-coated dipstick is selectively receivable by the central fill port of a rotor of a blood centrifuge. The dipstick includes an elongated, rod-like member having a first axial end and an opposite second axial end, and a cap affixed to the second axial end. At least a portion of a surface of the rod-like member is coated with an anticoagulant. The elongated rod-like member of the dipstick is dimensioned in length and diameter to be receivable through the central fill port of the rotor to contact a blood sample contained therein. The cap is circular in shape, with a diameter that is greater than that of the rotor fill port to entirely cover and seal the fill port to prevent leakage therethrough of a blood sample contained in the rotor, especially when the rotor is gently agitated or inverted.Type: GrantFiled: October 28, 2008Date of Patent: September 20, 2011Assignee: IDEXX Laboratories, Inc.Inventor: Alyssa J.

Patent number: 6730071Abstract: A blood collection bag assembly is provided. The assembly includes a flexible blood collection bag, a length of flexible tubing extending from and communicating with the bag and a connector secured to the end of the flexible tubing remote from the bag. The connector includes a needle pierceable resealable closure secured in sealing engagement with the end of the flexible tubing remote from the bag. The connector can be used with a conventional needle holder, such as the type used to collect specimens of blood into an evacuated tube. The blood collection bag assembly has no sharp components, and hence is safe and easy to use. Additionally, the blood collection bag assembly can be used with conventional evacuated tubes to avoid cut and drip techniques for collecting specimens of blood for analysis.Type: GrantFiled: September 25, 2000Date of Patent: May 4, 2004Inventor: Alyssa J.

Patent number: 6142957Abstract: In an aspect, the invention relates to an instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and has a distal end constructed to sever and remove a tissue sample from the body, including tissue specimens, polyps or the like. The improvement includes that the instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position.Type: GrantFiled: January 27, 1997Date of Patent: November 7, 2000Assignee: Boston Scientific CorporationInventors: Bruce H.

Patent number: 5840044Abstract: The invention features a device for obtaining tissue samples from a site deep within the body having a proximal portion constructed to follow a long torturous path to the site and a distal portion constructed with a jaw arrangement that can be opened and closed to sever a sample, including tissue specimens, polyps and the like, from the surface. The device is constructed for severing and storing at least three successive samples. The device includes a sample storing and retaining element in the space encompassed by the jaws. The element is fixed to maintain an orientation extending generally distally along a selected length to a distal end and has a profile along the length for engaging multiple samples arranged axially in the order in which they were severed from the surface with sufficient frictional force to substantially retain the samples from moving distally from the space encompassed by the jaws when the jaws are opened to sever a successive sample from the surface.Type: GrantFiled: April 3, 1996Date of Patent: November 24, 1998Assignee: Boston Scientific CorporationInventors: Alyssa J.

Patent number: 5505714Abstract: A non-rotational catheter clamp. The clamp comprises a snap-acting device which contains a rotatable inner and outer member. The inner member has an inner passageway for a catheter and an outer surface containing at least one protrusion. The outer member has an interior beveled sidewall. When the outer member is twisted or rotated in a first direction relative to the inner member, the protrusion on the inner member is compressed by the beveled sidewall, thereby compressing the inner member and the catheter. When the outer member is twisted in the opposite direction relative to the inner member, the protrusion disengages from the beveled sidewall and the catheter is decompressed. Use of the clamp in conjunction with a catheter contamination sleeve is disclosed.Type: GrantFiled: July 28, 1994Date of Patent: April 9, 1996Assignee: Arrow International Investment Corp.Inventors: Alyssa J.
