Publication number: 20090192542Abstract: An improvement on the extra-amniotic balloon and technique of placement is disclosed. It involves a large capacity balloon, modified to efficiently place pressure on the cervix, and markers for ease and of placement. The malleable introducing stylet allows for safe and easy insertion, either manually or visually, through a cervix that is 0.5 cm or more in dilation. The optional traction collar can aid in more efficiently placing pressure on the cervix. The automatic pump for instillation of the fluid has a forward and reverse mode to allow for deflation and repositioning of the balloon if placement is less than optimal. This process can be performed by a physician or a nurse, already certified in the placement of fetal scalp electrodes or intrauterine pressure catheters. Additionally, the procedure can be performed by one person.Type: ApplicationFiled: April 2, 2009Publication date: July 30, 2009Applicant: APPLE MEDICAL CORPORATIONInventor: Steven B. Harter

Publication number: 20070100335Abstract: A cervical biopsy instrument that includes a central shaft defining a longitudinal axis and a stop extending laterally from the shaft. The stop typically is formed in substantially the shape of a circle in a plane disposed at substantially right angles to the central axis of the shaft. The instrument also includes an electrode extending from an endocervical portion of the shaft to the stop. The stop may be formed in the shape of a complete circle, or a partial circle. Any free ends are configured to be rounded and extend inwardly toward the shaft or away from the endocervical portion to prevent the presentation of sharp edges or the like which could be caught on irregularities of the uterine cervix. The stop may be affixed to the central shaft along a tangent, or ends of the stop may be affixed to the central shaft. In another embodiment, the stop encircles or partially encircles the shaft, with the shaft extending substantially through the center of the circle.Type: ApplicationFiled: October 28, 2005Publication date: May 3, 2007Applicant: Apple Medical CorporationInventor: Nathan Fischer

Patent number: 7033319Abstract: An adjustable retractor is disclosed comprising an inner ring, an outer ring spaced from the inner ring, and an elongate sleeve open at opposite ends. The sleeve is provided and extends between the inner and outer rings and is connected at the opposite ends to the rings. The outer ring is provided with a pre-loaded rotational torque to assist with rotation of the outer ring about its central axis to roll the sleeve about the outer ring to adjust sleeve length. An obstetrics version of the retractor may be used for caesarean sections. A hydraulically controlled retractor includes fluid channels in the inner and outer rings that may be dilated by injection of an appropriate fluid.Type: GrantFiled: April 20, 2004Date of Patent: April 25, 2006Assignee: Apple Medical CorporationInventors: John C. Pulford, Marco Pelosi

Patent number: 6723044Abstract: An adjustable retractor is disclosed comprising an inner ring, an outer ring spaced from the inner ring, and an elongate sleeve open at opposite ends. The sleeve is provided and extends between the inner and outer rings and is connected at the opposite ends to the rings. The outer ring is provided with a pre-loaded rotational torque to assist with rotation of the outer ring about its central axis to roll the sleeve about the outer ring to adjust sleeve length. The outer ring may be formed in a mobius configuration to provide the pre-loaded rotational torque. The outer ring has a cross-sectional shape that may have numerous different configurations. The mobius configuration may include the cross-sectional shape having an outer circumference offset by a predetermined amount about the central axis of the outer ring proceeding longitudinally along the central axis from one location on the outer ring to another location on the outer ring. A method of adjusting a retractor is also disclosed.Type: GrantFiled: March 14, 2002Date of Patent: April 20, 2004Assignee: Apple Medical CorporationInventors: John C. Pulford, Marco Pelosi

Patent number: 5437646Abstract: A laparoscopy cannula reducer has at its proximal end a resilient end seal carrying a resilient tri-cuspid valve; the valve is passive, yet allows sealing of a body cavity in surgical procedures to prevent fluid flow between the atmosphere and the body cavity, both when an instrument is carried within the cannula and when the cannula is not being used for passage of an instrument to the body and the reducer has handgripping portions for applying and disengaging the reducer over a laparoscopy cannula.Type: GrantFiled: May 27, 1993Date of Patent: August 1, 1995Assignee: Apple Medical CorporationInventors: Robert B. Hunt, Robert W. Schaefer
