One aspect of the present disclosure includes a delivery tool configured to deliver a neurostimulator into a pterygopalatine fossa of a subject. The neurostimulator can include a body connected to an integral stimulation lead having one or more stimulating electrodes. The delivery tool can comprise a handle, an elongated shaft extending from the handle, a hub portion, and a double barrel sheath. The hub portion can be located between the shaft and a spine member that extends axially away from the hub portion. The hub portion can be sized and dimensioned to releasably mate with the neurostimulator. The double barrel sheath can be connected to the spine member. A central lumen can extend through at least a portion of the shaft and the hub portion. The central lumen can be adapted to receive a lead ejector for selective deployment of the stimulation lead from the double barrel sheath.

Surgical tools and methods for delivering a neurostimulator into the pterygopalatine fossa

A surgical tool configured to facilitate delivery of a neurostimulator to a craniofacial region of a subject includes a handle portion, an elongate shaft having a contoured distal portion, and an insertion groove on the elongate shaft. The elongate shaft is configured to be advanced under a zygomatic bone along a maxillary tuberosity towards a pterygopalatine fossa. The distal portion includes a distal dissecting tip. The insertion groove is configured to receive, support, and guide a medical device or instrument.

Surgical tools to facilitate delivery of a neurostimulator into the pterygopalatine fossa

One aspect of the present disclosure includes a neurostimulator delivery apparatus. The apparatus includes a handle portion, an elongate shaft extending from the handle portion, and a distal deployment portion. The distal deployment portion is configured to releasably mate with a neurostimulator. The neurostimulator is sized and configured for implantation into a craniofacial region of a subject.

A transition apparatus for use with a medical device having an elongate element is disclosed. The apparatus may include a body defining a lumen for housing at least a portion of the elongate element. The body may have a proximal end configured for releasable connection to the medical device and a distal end. The apparatus may further include a connection piece connected to the distal end of the body. The connection piece may have a first opening configured to receive the elongate element from the lumen of the body and a second opening configured to receive the elongate element from the first opening and direct the elongate element toward the body. A method of connecting a transition apparatus to an ablation device having a leash is also disclosed.

A high intensity focused ultrasound transducer includes an ultrasonic emitter having a surface that emits ultrasonic energy along a beam path, at least one low attenuation polymeric ultrasonic lens acoustically coupled to the surface in the beam path of the ultrasonic energy, such that the lens can direct the ultrasonic energy in at least one direction, and at least one stress mitigation feature, such as a kerf, a heat sink, or an acoustic matching layer, to mitigate thermal expansion mismatch stresses within the transducer. For manufacturing simplicity, the first surface is typically either flat or monotonically curvilinear. The lens may take a variety of shapes, including Fresnel features, and may focus, collimate, or defocus the ultrasonic energy. Any orientation and positioning of the at least one ultrasonic lens relative to the first ultrasonic emitter is contemplated. Manufacture is further simplified by molding, casting, or thermoforming the lens.

A carrier for an ablation element is provided. The carrier includes a plurality of walls defining a receiving portion configured to receive at least a portion of an ablation element. A plurality of connection formations are disposed on an exterior surface of least one of the plurality of walls. Each of the plurality of connection formations is disposed at a different vertical position of the carrier. A device for epicardial ablation is also provided. The device includes a plurality of carriers disposed adjacent to each other. Each carrier includes a plurality of walls defining a receiving portion configured to receive at least a portion of an ablation element. A plurality of connection formations are disposed on an exterior surface of at least one of the plurality of walls of each carrier. Each of the plurality of connection formations is disposed at a different vertical position of a carrier.
