  • Patent number: 6607494
    Abstract: A cytology cell sampler for use in collecting mucosal cell samples from a human comprising a handle and a head portion. The handle is grasped by the operator and the head portion is then abutted a patient's mucosal surface for sample collection. The head portion has a first plate and a plurality of secondary plates with the first plate attached to the handle opposite the end grasped by the operator. The first plate has a longitudinal axis generally along a longitudinal axis of the handle, and the plurality of secondary plates project from the first plate generally perpendicular to the longitudinal axis of the first plate. There is at least one collection space between the plurality of secondary plates. Each secondary plate has a shaped free edge for contacting the mucosal surface of the human, collecting a sample between the plurality of secondary plates by scraping the mucosal surface with the shaped free edges.

  • Publication number: 20020120265
    Abstract: The present invention goes to a tissue electrocautery device that accommodates anatomical structures lying at more than one longitudinal axes. Such a circumstance is encountered when attempting to perform symmetric tissue electrocautery of an endocervical canal where the longitudinal axis of the vaginal vault is at an angle to the longitudinal axis of the endocervical canal. The device of the present invention uses a hollow housing, elongate along a first longitudinal axis, having a proximal portion with a proximal end and a distal end, and includes a distal portion from the distal end. The distal portion is elongate along a second longitudinal axis and pivotable in relation to the proximal portion at a selectable angle to the first longitudinal axis.

  • Patent number: 6418930
    Abstract: An incontinence pessary device for use within a vaginal vault of a woman, the incontinence pessary device comprising a resilient main support body, at least two resilient lateral support bodies, and a suburethral support body. The resilient main support body has a primary plane of orientation that will correspond to the sagittal plane of the woman's pelvis when inserted and be at least responsive to forces oriented along the main plane. The at least two resilient lateral support bodies project from a position on the main support body toward generally opposite sides of the main support body in a secondary plane generally perpendicular to the primary plane. Thus, when inserted, the at least two resilient lateral support bodies provide lateral and additional rotational stabilization, being at least responsive to forces oriented along the secondary plane.

  • Patent number: 5951490
    Abstract: A uterine curette device for curetting the endometrial lining the uterus using a cannula having a hollow curetting head including at least one longitudinal blade and corresponding slot through which endometrium can be suctioned into the curetting head. The at least one longitudinal blade bowing outward and having two margins with at least one margin having a curetting edge where the margin meets the outer surface of the curetting head. Endometrium is curetted by rotating the cannula about its longitudinal axis so that the at least one curetting edge curettes off the endometrial sample which is then suctioned into the cannula.
