Abstract: The present invention generally provides a polyaxial fixation device having a shank with a spherical head formed on a proximal end thereof, and a receiver member having an axial passage formed therein that is adapted to polyaxially seat the spherical head of the shank. The polyaxial bone screw further includes an engagement member that is adapted to provide sufficient friction between the spherical head and the receiver member to enable the shank to be maintained in a desired angular orientation before locking the spherical head within the receiver member.

Abstract: A tissue resecting device includes an end effector assembly including a proximal hub housing and a cutting member extending distally from the proximal hub housing, and a handpiece assembly. The handpiece assembly includes a handle housing, a drive casing extending distally from the handle housing, a drive rotor extending through and distally from the drive casing, and a seal ring disposed about the drive rotor. In an at-rest position, the seal ring is sealingly engaged between the drive casing and the drive rotor to inhibit fluid ingress into the annular space. Upon engagement of the end effector assembly with the handpiece assembly, a portion of the proximal hub housing is configured to urge the seal ring from the at-rest position to a displaced position wherein the seal ring is displaced from the drive rotor to reduce friction therebetween upon rotation of the drive rotor relative to the drive casing.

Abstract: A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. An auxiliary vacuum source is configured to selectively provide additional vacuum to increase suctioning of cut tissue through the inner cutting shaft and into the vacuum generator.

The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. The tissue collection cartridge may include at least one histological agent disposed therein, may include a fill indicator configured to indicate a fill level of tissue within the tissue collection cartridge, and/or may include a latch configured to seal the port closed.

Abstract: A surgical system includes a fluid source including a fluid inflow tube, a fluid delivery device coupled to the fluid inflow tube and configured to deliver fluid from the fluid source into a patient, a surgical instrument, and a control box coupled to the surgical instrument. The control box includes one or more waste heat-generating electronic components and a heat pipe assembly disposed in thermal communication with the one or more waste heat-generating electronic components. The fluid inflow tube is disposed in thermal communication with the heat pipe assembly of the control box such that the heat pipe assembly conducts heat away from the one or more waste heat-generating electronic components and heats fluid flowing through the fluid inflow tube.

Abstract: The present invention generally provides a polyaxial fixation device having a shank with a spherical head formed on a proximal end thereof, and a receiver member having an axial passage formed therein that is adapted to polyaxially seat the spherical head of the shank. The polyaxial bone screw further includes an engagement member that is adapted to provide sufficient friction between the spherical head and the receiver member to enable the shank to be maintained in a desired angular orientation before locking the spherical head within the receiver member.

Abstract: Methods for effectuating ovarian denervation include advancing a disruptor intravaginally to access an ovarian nerve and applying the disruptor to the ovarian nerve to denervate the ovarian nerve to limit ovarian sympathetic neural activity and control hormonal secretion.
