Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.

Hydrodissection and posterior capsule opacification prevention during capsulotomy procedure

An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a jaw assembly defining a longitudinal axis and including a pair of jaws. Each jaw includes a proximal portion pivotally connected to the distal hub assembly; and a distal portion extending distally of the proximal portion thereof. The end effector additionally includes an actuation cable having a distal end operatively connected to the pair of jaws and a proximal end operatively connected to the at least one motor. In use, axial translation of the actuation cable results in one of an opening and a closing of the jaw assembly.

Wrist and jaw assemblies for robotic surgical systems

A laparoscopic instrument assembly with a handle member and a removable tip. The handle member and removable tip are mated using a double threaded design which provides a secure connection with low electrical resistance. Electrical energy is provided through an inner shaft to the removable tip, and a return energy path is formed using an outer tubing of the instrument assembly. The removal tip includes a cutting and sealing device with a resistive member that is provided with the electrical energy, thereby enabling the tip to cut and seal tissue.

Laparoscopic medical device with de-mateable tip

A tissue cutting and sealing device, having a pair of opposing elements dimensioned to grasp tissue therebetween; and a heating assembly on at least one of the opposing elements, wherein the heating assembly includes: a ceramic body; and a metalized portion extending along a top surface of the ceramic body. The top surface of the ceramic body preferably has a width greater than the metalized portion.

Thermal cautery and thermal ligating devices improved by the addition of a thermally conductive plate proximate the resistive heating element used in those devices.

Thermal cautery devices with improved heating profiles

A device for handling tissue; including: a main body; a pair of opposing arms connected to the main body, the opposing arms having working surfaces thereon; a heating element disposed on one of the working surfaces; and a resistive element wired in parallel with the heating element.

System for regulating heating in a tissue sealing and cutting device

A resistance heater for use in a tissue sealing and cutting device, including a tubular heating element adapted to conduct current therethrough; and a thermally conductive electrical insulator disposed within the tubular heating element.

Tubular resistance heater with electrically insulating high thermal conductivity core for use in a tissue welding device

A medical device for photodynamically treating cancerous tissue, such as prostate cancer, comprising a body, a needle extendable from the body and at least one light-emitting (e.g., laser) diode mounted on the needle. The body is sized and configured for introduction into the urethra of a patient. The needle is movable between a retracted position housed substantially within the cylindrical body, and a deployed position in which the needle extends from the cylindrical body to enable it to penetrate into prostate tissue. The light-emitting diode is adapted to emit light to activate a photosensitizing agent (e.g., porfimer sodium) in or adjacent cancerous tissue in the prostate. Methods of treating cancer and other embodiments of medical devices for cancer treatment are also disclosed.

Method of testing thermal cautery devices

A method for treating tissue of a mammalian body in which the conductivity of the tissue is characterized. The amount of a conductive liquid to supply to the tissue is determined as a function of the conductivity of the tissue and injected into the tissue over an interval of time. Electromagnetic energy is supplied to the tissue to form a lesion in the tissue. A computer-readable memory and a radio frequency generator and controller utilizing such method are further provided.

Method for treating tissue with a wet electrode and apparatus for using same

A transurethral apparatus for radio frequency ablation treatment of the prostate having prostatic tissue of a human male having urethra which extends through the prostate comprising an elongate probe sized so that it is adapted to be introduced into the urethra and having a passageway extending therethrough. The elongate probe has proximal and distal extremities. Proximal and distal pairs of needle electrodes are provided which are carried by the distal extremity of the probe. A control mounted on the proximal extremity of the probe and extends through the passageway and is coupled to the proximal and distal pairs of needle electrodes for movement of the needle electrodes into and out of the prostate. A RF generator is provided for supplying RF energy to the needle electrodes for solely creating bipolar ablation with respect to the proximal and distal pairs of needle electrodes.
