A catheter for intraluminal lithotripsy including an outer wall, at least one balloon extending from the outer wall, the balloon having a first portion, a second portion proximal of the first portion and an intermediate portion between the first and second portions such that a transverse dimension of the intermediate portion is less than a transverse dimension of the first and second portions. The catheter includes a first lumen, at least one energy emitter mounted on the balloon for emitting energy to break down or soften calcium and a connector connecting the at least one energy emitter to an external energy source, the connector extending through the catheter.

Certain aspects of the present disclosure generally relate to ophthalmic surgery, and more particularly, to methods and apparatuses for controlling intraocular pressure (IOP) and administering ocular tamponades during or after ophthalmic surgery. An exemplary apparatus generally includes a proximal segment having a first inner diameter (ID), a first proximal end, and a first distal end. The apparatus further includes a distal segment having a second ID smaller than the first ID, a second proximal end, and a second distal end configured to be disposed inside a hub or a cannula transition of a valved cannula comprising the hub, a shaft, and the cannula transition between the hub and the shaft.

A medical device that includes a first body including a first actuation member including a first connector and a second actuation member. The medical device includes a second body for attachment to, and detachment from, the first body. The second body including an actuation wire, a second connector at a proximal end of the actuation wire, and a valve having one or more channels for receiving a material. Attachment of the first body with the second body results in the first connector engaging the second connector, such that movement of the first actuation member causes a corresponding movement of the actuation wire. Moving the second actuation member into the second body to interact with the valve is configured to selectively direct the material through the one or more channels.

A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer; measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer; comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

An atherectomy system includes a handle having a handle housing and a drive motor that is disposed within the handle housing and is adapted to rotate a drive cable extending through the handle and operably coupled to an atherectomy burr. A supply line extends from the handle housing. A supply line fitment may be disposed relative to the handle housing and may be configured to releasably secure the supply line relative to the handle housing such that the supply line is directed away from the handle housing in a direction that is selected from two or more directions.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

The present disclosure relates generally to medical devices and the use of medical devices for the treatment of vascular conditions. Particularly, the present disclosure provides devices and methods for using a vibrational wire guide to cut and/or core through a venous obstruction, such as a chronic clot.

The present disclosure relates to a device for meniscal repair for use in areas of a human body where tissue can either be surgically reattached to bone or surgically repaired when a tear forms in the tissue. The device may take one of three forms; in a first form, the device comprises a handle and a deployment member permitting the deployment of anchors or sutures to the tissue requiring repair; subsequently the device may take a second form comprising the handle, still in place, and a cutter member for manipulating and cutting anchors and sutures to assist in repair of the tissue; in its third form, the device comprises the handle, still in place, and a fluid injection member for applying a fluid to aid in improving biological conditions for the tissue to heal.

According to some embodiments, a medical instrument (for example, an ablation device) comprises an elongate body having a proximal end and a distal end, an energy delivery member positioned at the distal end of the elongate body, a first plurality of temperature-measurement devices carried by or positioned within the energy delivery member, the first plurality of temperature-measurement devices being thermally insulated from the energy delivery member, and a second plurality of temperature-measurement devices positioned proximal to a proximal end of the energy delivery member, the second plurality of temperature-measurement devices being thermally insulated from the energy delivery member.

A medical device, a cooling-fluid/rinsing-fluid hose, and a method for using a medical device. The medical device includes a handpiece with an interior enclosed by a handpiece housing, preferably for receiving a drive. The medical device also has an effector arranged on or coupleable to the handpiece and a supply device for supplying cooling fluid and/or rinsing fluid to the effector. The supply device includes a guide tube or guide cannula that passes through the interior in the handpiece longitudinal direction and is rigidly connected to the handpiece. The guide tube or guide cannula, which opens to the outside in a distal and in a proximal handpiece region, longitudinally guides a preferably single-use cooling-fluid/rinsing-fluid hose that is pushed into the guide tube.
