Neuromodulation cryotherapeutic devices and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment of the present technology can include an elongated shaft having distal portion and a supply lumen along at least a portion of the shaft. The shaft can be configured to locate the distal portion intravascularly at a treatment site proximate a renal artery or renal ostium. The supply lumen can be configured to receive a liquid refrigerant. The cryotherapeutic device can further include a cooling assembly at the distal portion of the shaft. The cooling assembly can include an applicator in fluid communication with the supply lumen and configured to deliver cryotherapeutic cooling to nerves proximate the target site when the cooling assembly is in a deployed state.

Neuromodulation cryotherapeutic devices and associated systems and methods

An example medical device includes a balloon that is inflatable to an inflated configuration. The balloon includes a non-compliant layer coextruded on an inner layer, and an outer layer coextruded on the non-compliant layer. The non-compliant layer is configured to delaminate from the inner and the outer layers in the inflated configuration. The non-compliant layer may be configured to rupture in the inflated configuration. An example technique includes inflating the balloon to a predetermined pressure sufficient to rupture the non-compliant layer and insufficient to rupture both the inner and outer layers. The example technique further includes deflating the balloon, and introducing the balloon into a vasculature. Another example technique includes coextruding a non-compliant layer on an inner layer, coextruding an outer layer on the non-compliant layer, and forming a balloon from the inner layer, the non-compliant layer, and the outer layer.

Multilayer balloons

A surgical instrument includes an outer shaft defining a passageway. An inner shaft is disposed within the passageway and defines a lumen. An expandable structure has a first end coupled to a second end of the outer shaft and a second end coupled to a second end of the inner shaft. The expandable member defines a chamber. A delivery shaft includes a first end positioned within the passageway and a second end positioned within the chamber. The delivery shaft defines a channel configured to deliver a coolant out of an opening in the second end of the delivery shaft and into the chamber to move the expandable structure from an unexpanded configuration to an expanded configuration. A variable exhaust valve is in communication with the passageway and is configured to regulate pressure within the chamber. Systems and methods are disclosed.

Cryogenic kyphoplasty instrument and methods of use

Methods for manufacturing an endovascular stent having channel(s) formed therein for containing a therapeutic material. A molding and sintering process forms a thin-walled tubular component having a tubular core structure encapsulated therein. Portions of the thin-walled tubular component are removed to form at least a portion of the endovascular stent in a pattern corresponding to that of the tubular core structure such that the tubular core structure or corresponding channel(s) left thereby are captured within a wall of the formed stent. The tubular core structure is removed to leave a corresponding channel(s) in its stead. A plurality of holes is formed in the stent wall for filling the stent channel(s) with the therapeutic material and for eluting the therapeutic material therefrom.

Methods of manufacturing a drug-eluting stent

Catheter apparatuses, systems, and methods for cryogenically modulating neural structures of the renal plexus by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a cryo-applicator to a renal artery via an intravascular path. Cryogenic renal neuromodulation may be achieved via application of cryogenic temperatures to modulate neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

Cryoablation apparatuses, systems, and methods for renal neuromodulation

Cryotherapeutic systems with features that can facilitate pressure relief in the event of exhaust-passage blockage and associated devices, systems, and methods are disclosed herein. A cryotherapeutic system configured in accordance with a particular embodiment can include an elongated shaft having a distal portion and a pressure-relief portion proximal to the distal portion. The cryotherapeutic system can further include a supply lumen, an exhaust passage, and a balloon configured to receive refrigerant from the supply lumen and to exhaust refrigerant to the exhaust passage. The pressure-relief portion can be configured to release refrigerant from the exhaust passage when a pressure of refrigerant in the exhaust passage exceeds a threshold pressure less than a pressure rating of the balloon. The pressure-relief portion, for example, can include a rupture element configured to rupture at about the threshold pressure.

Shafts with pressure relief in cryotherapeutic catheters and associated devices, systems, and methods

Endovascular nerve monitoring devices and associated systems and methods are disclosed herein. A nerve monitoring system configured in accordance with a particular embodiment of the present technology can include a shaft having a proximal portion and a distal portion and a nerve monitoring assembly at the distal portion. The shaft is configured to locate the distal portion intravascularly at a treatment site. The nerve monitoring assembly can include a bipolar stimulation electrode array and a bipolar recording electrode array disposed distal to the bipolar stimulation electrode assembly.

Endovascular nerve monitoring devices and associated systems and methods

A package includes a box having an interior volume and a first pocket disposed at a first corner of the box. The first pocket includes a lip configured for a finger of a user to be inserted therein for removal of the package from a storage unit.

Package for a medical device

A cryotherapeutic device having an integral multi-helical balloon section and methods of making the same. A method of forming the cryotherapeutic device can include forming an extruded integral shaft having first and second substantially parallel lumens. The method can further include twisting a distal section of the shaft such that the first and second lumens form intertwined helical portions. The first and second helical portions can be plastically enlarged to form an inflatable body configured to deliver therapeutically effective cryogenic cooling to a treatment site.
