Embodiment Construction

[0012] It is contemplated that embodiments of the present invention may be utilized for the collection of cells or tissue samples from the body of a patient for medical testing. However, collection of cells or tissue samples from the uterus of a patient will be discussed below in an exemplary manner.

[0013] In one aspect of the present invention, a device for collecting cells and other biological materials is presented. The medical device is comprised of a distal end portion for collecting cells, such distal end comprising a substantially porous tip; a proximal end portion comprising a pump; and an elongated middle portion comprising a lumen in fluid connection with the distal and proximal end portions and extending therethrough.

[0014] According to a preferred embodiment, the substantially porous tip is comprised of an open cell flexible material such as foam or sponge. The foam may be comprised of polyolefin, urethane, polyurethane, or silicone materials. In a preferred embodiment...

Abstract

This invention relates generally to medical devices, and more particularly, an apparatus and method for collecting cells or tissue samples from the cervix of a patient for medical testing.

Description

FIELD OF THE INVENTION [0001] This invention relates generally to medical devices, and more particularly, an apparatus and method for collecting cells or tissue samples from the cervix of a patient for medical testing. BACKGROUND OF THE INVENTION [0002] Cancer is responsible for significant health problems in populations of women in the United States and throughout the world. In particular, gynecological cancers, including ovarian, uterine, cervical, and vuvlar cancers, are responsible for over 5,000 deaths in the United States each year. Although recent years have seen advances in detection and treatment of these cancers, mortality rates remain significantly high. [0003] Cervical cancer can be prevented and possibly cured if detected early enough in its precancerous or precursor stages. There are a variety of known techniques for the early detection of cervical cancer. Most of these techniques include the scraping or sampling of tissue from the uterine or endocervical canal using a...
