Abstract: Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps.

The lead body is configured to have a non-planar contour that folds or curves about the central axis when experiencing the fluid pressure.

Abstract: A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.

Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating one or more abrasive elements within the vessel. The abrasive elements are attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that spirals around the drive shaft in a direction that is opposite to the wind direction of filars of the drive shaft, and opposite to the direction of rotation. In some embodiments, a concentric abrasive tip member is affixed to and extends distally from a distal-most end of the drive shaft.

Abstract: A biosensor inserter includes a push member with a push element, a contact member including a latch, a transmitter carrier supporting a transmitter and sensor assembly, and a pivot member having a latch end, the pivot member supporting an insertion device during biosensor insertion. In operation, the push member is telescoped axially by the user relative to the contact member, which is provided in contact with a user's skin. This pushes the push element against the pivot member and translates the transmitter carrier during insertion of the biosensor. During a first portion of a stroke of the insertion device, insertion of the biosensor is accomplished, and the pivot member is prevented from pivoting. In a second portion of the stroke, after latch end moves past the latch, the pivot member is allowed to pivot and the insertion device is retracted. Other system and method embodiments are provided.

Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.

Abstract: The present innovation is a customized compression device for prevention and treatment of keloids and hypertrophic scarring, primarily a frequent complication of ear piercing. The “one size fits all” design of traditional devices can compromise efficacy due to uneven fit and compression. This invention harnesses 3D digital scanning to capture the intricate contours of the ear for every patient, for personalized compression therapy. Using 3D printing, shells are fabricated with biocompatible materials such as Polylactic Acid, shape memory polymers, or silicone-based substances. In primary embodiments, device functionality is achieved with compression clips or spring-open, single-piece structures. The custom fit, potential for infusion of therapeutic agents (e.g., corticosteroids), and engineered porosity combine to improve keloid management from uniform pressure distribution and optimal healing. Additionally, the ‘shells’ can be pigmented to match patient skin tones and encourage compliance.
