A medical treatment device is disclosed herein. In one example, the medical treatment device includes a core assembly which has a first conduct and a second conductor, the second conductor being formed from a first conductive material. An insulative material can surround the second conductor and define one or more uninsulated portions. A second conductive material can surround the first conductive material along at least a portion of the one or more uninsulated portions and can have a higher electrical conductivity than the first conductive material. The medical treatment device can include an interventional element formed from a third conductive material that electrical couples to the first conductor. A fourth conductive material can be disposed over the third conductive material and have a higher electrical conductivity than the third conductive material.

The present disclosure includes catheter systems and methods for treatment of occlusions, including coronary artery chronic total occlusions. The catheter system comprises a catheter coupled to a control system with a distal end inserted into a patient and proximal to a location within a blood vessel with an occlusion. The catheter comprises a flexible outer sheath surrounding a housing with a plurality of lumens to perform various functions to penetrate occlusions.

An in vivo temperature control system has a monitor for the internal temperature of a biological organ such as the esophagus, and for directly controls the temperature in the organ side depending on the monitoring. The in vivo temperature control system includes: a catheter insertable into a living body; a temperature probe containing a temperature sensor, the probe being insertable into the catheter; a liquid storage section for storing a temperature-controlled liquid; a pump for supplying the liquid from the liquid storage section to the catheter; and a control section for controlling driving of the pump based on a signal detected from the temperature probe; wherein the control section controls the pump when the signal has reached a preset threshold, and the pump is driven such that the liquid in the liquid storage section is released to the outside through the catheter.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

An adaptive flow rate control system for a surgical device, whereby the control system includes one or more nonintrusive sensors configured to be positioned on an aspiration conduit extending downstream from a handheld surgical device to measure flow and reduce clogging within the aspiration conduit is disclosed. The nonintrusive sensor may provide data to a controller of a handheld surgical device system to enable it to control operation of the handheld surgical device based at least in part on the data from the adaptive flow rate control system to prevent clogging of the aspiration system. The adaptive flow rate control system may also include a clog tracking module and a clog prediction module. The adaptive flow rate control system may include a wireless communication system configured to communicate with other components of a surgical device system and may communicate with a external network and resources on the internet.

An improved multifunction cable for use in an operating room avoids the usual tangle of wires and tubes can be a significant hazard. The cable comes pre-sterilized with a number of wires and tubes pre-installed in a protective housing making it easy to conduct myriad wires and tubes from one region of the operating room to another without any possibility of tangling or violation of sterility. At the sterile end of the cable a special terminus acts as a holder to keep the various operating instrument organized. The terminus is designed to accept a special smoke evacuating monopolar electrosurgery instrument.

Example electrosurgical devices and systems are disclosed. An example electrosurgical device includes a body, an electrosurgical electrode secured to the body, the electrosurgical electrode including a distal tip. The electrosurgical device also includes a shroud translatable relative to the electrosurgical electrode between a first position and a second position, a first magnetic component which is operably connected to the body, and a second magnetic component which is operably connected to the shroud, wherein the first and second magnetic components magnetically interact to releasably maintain the shroud in the first position.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

Intraluminal ultrasound devices, systems and methods are provided. In one embodiment, an intraluminal ultrasound device includes a flexible elongate member configured to be positioned within a body lumen of a patient, the flexible elongate member including a distal portion and a longitudinal axis; and a transducer array disposed at the distal portion of the flexible elongate member and circumferentially positioned around the longitudinal axis of the flexible elongate member. The transducer array includes a plurality of micromachined ultrasound transducers (MUTs). In addition, the transducer array is configured to obtain ultrasound imaging data of the body lumen in response to a first electrical signal, and apply an ultrasound therapy within the body lumen in response to a second electrical signal.

An electrosurgical wand is provided and includes a handle and an elongate shaft coupled to the handle and extending distally from the handle along an axis. An active electrode is disposed at a distal end of the electrosurgical wand. A return electrode abuts the elongate shaft and extends along and annularly about the axis. The return electrode has a top side adjacent the active electrode and an opposite bottom side and defines a notch. A support member is disposed in the notch between the electrodes and transitions curvilinearly from the notch to define a front surface extending laterally across and axially from the return electrode. The front surface tapers downwardly from the active electrode to define a first portion defining a first convex outer surface and also extends toward the bottom side of the return electrode to define a second portion defining a second convex outer surface.
