Abstract:

Embodiments of the present invention include a medical probe having an insertion tube, a basket assembly, an axial electrode, and a plurality of radial electrodes. The insertion tube is configured for insertion into a body cavity of a patient. The basket assembly has a proximal end that is connected distally to the insertion tube and includes a plurality of resilient spines, which are configured to bow radially outward from an axis of the basket assembly and are conjoined at a distal end of the basket assembly. The axial electrode is disposed at the distal end of the basket assembly, having a diameter of at least 1.5 millimeters, and is configured to contact tissue in the body cavity. The plurality of radial electrodes are configured to contact the tissue in the body cavity and include radial electrodes disposed on the spines.

International Classification:

A61B 18/14
A61B 18/12

Abstract:

Medical apparatus includes an insertion tube configured for insertion into a body cavity of a patient and an expandable assembly connected distally to the insertion tube and comprising electrodes, which are configured to apply electrical energy to tissue within the body cavity. A flexible porous sheath is fitted over the expandable assembly and configured to contact the tissue within the body cavity so that the electrical energy is applied from the electrodes through the sheath to the tissue.

A61M 1/00

Abstract:

A catheter that includes a mechanism for deflecting a distal portion of a catheter may include a deflection knob including a first thread, a rod including a second thread that is coupled to the first thread, and a puller wire that is connected to the rod. The rod may additionally include a pocket to which the puller wire may be connected via a joining feature that may be secured in the pocket and attached to a proximal end of the puller wire. The joining feature may include a first ferrule joined, e.g., crimped, to the proximal end of the puller wire and a second ferrule secured, e.g., bonded, in the pocket and joined, e.g., crimped, to the first ferrule.

B06B 1/02
B06B 1/06

Abstract:

A system and method include vibrating a needle of a phacoemulsification handpiece by driving one or more piezoelectric crystals in the handpiece with one or more electrical signals having different respective frequencies using one or more respective drive modules. The needle is inserted into an eye of a patient. The frequencies of the electrical signals are tuned to respective one or more target frequencies, and respective electrical impedances seen by the drive modules are registered. In response to an electrical impedance seen by at least one of the drive modules undergoing a change exceeding a preset impedance change, an indication is provided that material in the eye surrounding the needle has changed, a level of vibration of the needle is changed, and/or the frequency of at least one of the drive modules is adjusted to an electrical resonant frequency thereof.

Abstract:

An eye surgery system includes an Input/Output (I/O) device and a processor. The I/O device is configured to enable a user to define one or more eye surgery protocols, and further configured to, using the I/O device, present a graphical user interface (GUI) that displays one or more user defined eye surgery protocols. The processor is configured to (a) present the one or more user defined eye surgery protocols on the I/O device using the GUI, (b) test compatibility of the one or more user defined eye surgery protocols with the eye surgery system, and (c) provide an indication of the compatibility to a user of the eye surgery system.
