  • Patent number: 10864007
    Abstract: An abrading device and method for irritating and blotting a membrane, particularly the pleural membrane. The method uses a device which is small enough to be inserted and withdrawn through a thoracoport. The device includes a proximal end configured to be gripped by a surgeon and a distal end configured to be inserted into the patient. A stainless steel shaft connects the distal and proximal ends of the abrading device. The distal end includes a series of nylon bristles. The bristles are attached to the device wire wrapped around the distal end of the device. The connecting shaft and wrapped wire are malleable. Once the device is inserted, the surgeon grips the proximal end and manipulates the device so that the series of nylon bristles abrades the walls of the pleural space. Once the abrading process is complete, the surgeon can easily withdraw the device back through the thoracoport.

The apparatus comprises a handle with a hollow catheter flexibly extending distally from the handle. A cytology brush is stored within the hollow at a distal end of the cannula, and can be extended and retracted from the cannula by manipulating the handle. The cytology brush has a cylindrical proximal brush, a cylindrical distal brush, and a tissue collection gap longitudinally separating the proximal and distal brushes. The bristles of the brushes can have different material properties and can have an effective diameter greater than the cannula. In use, tissue samples accumulate within the bristles and within the tissue collection gap. When retracted into the hollow of the cannula, the apparatus maximizes the amount of tissue collected by folding the bristles over the tissue collection gap to shield the tissue samples collected within.

  • Patent number: 8864683
    Abstract: The present invention relates to a brush (1) for cleaning or sampling body tissue. The brush (1) comprises a support (2) that is provided with at least one row (3) of brush hairs (5) as well as one second row (4) of brush hairs (16). The first and second rows are mutually parallel and are situated next to one another. Each brush hair (5,6) has a proximal end (7) facing the support (2) and a distal end (9) facing away from the support (2). The first row (3) of brush hairs (5) comprises a strip (30) that extends in the longitudinal direction of the first row (3) and a longitudinal side (32) of which is fixed to the support (2). The proximal ends (7) of the brush hairs (5) in the first row (3) are fixed to the other longitudinal side (34) of the strip (30).

  • Publication number: 20140276210
    Abstract: A medical device for collecting cells includes a rotatable drive wire having a proximal portion, a distal portion, an offset portion of the distal portion, and a head member attached to the offset portion. The drive wire is coupled to an axially translatable rack member via a rotation mechanism that converts axial translation of the rack member into rotation of the drive wire. The offset portion of the drive will rotate eccentrically relative to the longitudinal axis of the drive wire to increase the diameter of the rotation of the head portion. The head portion can contact an inner surface of the body cavity to collect cells, and the eccentric rotation of the head member can limit trauma experienced by the patient relative to traditional scraping of a cell collection brush.
