An elongated medical needle includes an electrically-insulated elongated body having an outer surface extending between an electrically-insulated distal section and an electrically-insulated proximal section. An insulated electrically-conductive wire is aligned proximately along the outer surface between the electrically-insulated distal section and the electrically-insulated proximal section. An exposed electrically-conductive portion is mounted at the electrically-insulated distal section. The exposed electrically-conductive portion is electrically connected to the insulated electrically-conductive wire.

An incision instrument includes an insertion section and a manipulation section. The insertion section includes a first insulating member and an incision section inserted within the first insulating member. The incision section includes a tubular shaped first conductive member which has conductivity; a second conductive member disposed in the first conductive member; a contact section provided on an outer circumference surface of the second conductive member; and a second insulating member fixed to a distal end of the first conductive member and having an opening section. The manipulation section includes a manipulation main body section and a handle member. The second insulating member is positioned between the contact section and the first conductive section in a state in which the second conductive member is protruded from the opening section of the second insulating member.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

The invention relates to a tissue ablation system including an ablation device having a deployable applicator head configured to be delivered to a tissue cavity and ablate marginal tissue surrounding the tissue cavity. The deployable applicator head is configured to be delivered to a tissue cavity while in a collapsed configuration and ablate marginal tissue surrounding the tissue cavity while in an expanded configuration.

There is provided a medical instrument achieving a simple and efficient configuration. The medical instrument includes: an elongated part formed in a linear or tubular shape, at least a part of which is inserted into a living body; and an alloy part provided in the elongated part and formed from an alloy containing titanium and tantalum.

A coagulation suction device that includes a hollow suction tube, at least first and second bipolar wires, and an insulation cover. The hollow suction tube includes a closed distal tip, a proximal open end, and at least one suction opening positioned proximal of the closed distal tip. A position of the closed distal tip is adjustable relative to remaining portions of the hollow suction tube. The at least first and second bipolar wires extend along the hollow suction tube to the closed distal tip. The at least first and second bipolar wires each having an exposed distal end. The insulation cover encapsulates the at least first and second bipolar wires along a length of the first and second bipolar wires and terminates proximal of the exposed distal ends of the at least first and second bipolar wires.

The present invention is an ablation device having a screen sphere configuration for the ablation of marginal tissue surrounding a tissue cavity. The device includes a probe having a nonconductive elongated shaft including at least one lumen therethrough and a nonconductive distal portion extending from the shaft. The nonconductive distal portion includes a plurality distal ports and a plurality of proximal ports in communication with the at least one lumen of the shaft. The device further includes an electrode array including a plurality of independent conductive wires extending through the lumen and positioned along an external surface of the nonconductive distal portion, each of the plurality of wires passes through at least an associated one of the proximal ports and through at least a corresponding one of the distal ports.

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.

A dilation assembly comprises an expandable and contractible main body having a corrugated outer surface, a guide cannula configured to be disposed through the main body to guide a movement of the main body, and an anchor configured to fix the main body in a target position.

An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.
