摘要:
A surgical handle for use with an endoscopic instrument that is insertable into a body cavity insufflated with a gas. The surgical handle includes a housing having a mount that defines an opening for receiving the endoscopic instrument. A first elongated pusher tube is located within the housing and aligned with the mount opening. The pusher tube includes an interior passage that is in fluid communication with the endoscopic instrument. A first actuator moves the pusher tube longitudinally with respect to the mount opening. The interior passage is sized to permit the flow therethrough of insufflation gas escaping from the body cavity up to a predetermined rate, the rate being set at an amount that will not result in deflation of the body cavity.

A medical backcheck valve includes a hollow housing containing an upwardly biased piston assembly for controlling liquid flow therethrough. The piston assembly comprises a substantially rigid plug having one end protruding from the upper end of the housing, and a flexible sheath covering having a relatively small diameter upper end surrounding the plug, a main seal for controlling flow through said first flow space, and a tubular lower end, secured at the bottom of the housing, for preventing liquid from entering within the covering.

Apparatus and method for inserting intraocular lenses (IOLs) into eyes. The apparatus includes a tube, an elongated member having a tip secured to its distal end, and a rod having a distal end portion. The tip is softer than the distal end of the elongated member.
摘要:
A medical injection system includes an elongate injection apparatus and an actuator apparatus. The actuator apparatus includes a fitting for coupling the actuator apparatus to a delivery catheter and a reversible gripping means to grip the injection apparatus; the gripping means is included in a plunger that is slideably engaged with the fitting and directs the injection apparatus through a fitting lumen and through a catheter lumen, when the fitting is coupled to the catheter.
摘要:
Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).
摘要:
