Abstract: A device includes a body configured to be placed on an eye and multiple tine assemblies configured to secure the body to and release the body from the eye. The body includes multiple corners and multiple sides. Each corner includes a passage through the corner. Each side connects an adjacent pair of corners. Each tine assembly includes a twist pick configured to be inserted through one of the passages. Bottom surfaces of the sides are raised relative to bottom surfaces of the corners such that the bottom surfaces of the sides are spaced apart from the eye when the bottom surfaces of the corners are resting on the eye. Each of at least one side includes multiple openings configured to allow manipulation of a position of the body and a groove configured to receive a projection from a surgical tool in order to position the surgical tool on the eye.

Abstract: A surgical tool includes a housing having a driver and a surgical blade configured to be bi-directionally rotated by the driver. The surgical tool also includes a footplate configured to receive the surgical blade. The footplate includes a bottom portion configured to rest on ocular tissue of a patient's eye. The bottom portion includes a slot configured to allow passage of a portion of the surgical blade through the bottom portion of the footplate and into the ocular tissue of the patient's eye. The footplate also includes multiple walls having multiple openings. The openings are configured to receive additional portions of the surgical blade such that the surgical blade is rotatable relative to the footplate. The footplate further includes an additional opening or open side configured to allow viewing of the surgical blade and the slot during use.

Abstract: An ocular fixation device includes a body configured to be placed on an eye. The ocular fixation device also includes multiple twist picks configured to be turned to secure the body to the eye and to release the body from the eye. The body includes connection points on which a surgical tool is mountable on the body.

Abstract: A surgical tool includes a rocker assembly configured to cause rotation of a surgical blade to form an incision. The rocker assembly includes a gear. The surgical tool also includes a ratchet configured to rotate in a first direction and a second direction. The surgical tool further includes a linkage arm connecting the rocker assembly and the ratchet so that rotation of the ratchet causes rotation of the rocker assembly. In addition, the surgical tool includes a spring configured to be extended by the ratchet when the ratchet is rotated in the first direction. The spring is also configured to retract and cause the ratchet to rotate in the second direction.

Abstract: A method of radio frequency (RF) welding of a flexible PVC sheet to a rigid copolyester carrier by holding a flexible PVC sheet and a rigid copolymer carrier together between heated RF dies. A predetermined temperature differential is maintained between the RF dies, with the flexible sheet side at a higher temperature than the rigid carrier side and adjusted so that a weld plane is established along the interface between the PVC and the copolyester. An RF weld signal is passed through the first and second RF dies and the PVC and copolyester therebetween, so that the flexible PVC sheet and the copolyester rigid carrier partially melt and become welded together at the weld plane.

Abstract: A fluid infusion pump includes a disposable cassette having an inlet, an outlet, and a fluid chamber between the inlet and the outlet. There is a fixed wall of the fluid chamber and a movable wall of the fluid chamber. A pump body receives the cassette in a fixed operating relationship such that an actuator in the pump body is activatable for reciprocal advancement and retraction with respect to the cassette and is adapted to confront the movable diaphragm when the cassette is received in the pump body. There is a detachable coupling between the actuator mounted in the pump body and the movable wall so that fluid is expelled from the fluid chamber on advancement of the actuator and positively drawn into the fluid chamber upon retraction of the actuator.
