Abstract: An intraluminal imaging device that provides both flexibility and pushability is disclosed. The device includes a flexible elongate member configured to be positioned within a body lumen of a patient, and an imaging assembly disposed at the distal portion of the flexible elongate member and configured to obtain intraluminal image data. The distal portion of the flexible elongate member includes a region, proximal to the imaging assembly, that is less hard and/or more flexible than the proximal portion of the flexible elongate member. The more flexible region includes an inner member, an adhesive surrounding the inner member, a communication line embedded within the adhesive and configured to carry signals associated with the imaging assembly, and an outer polymer layer surrounding the adhesive.

Abstract: A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.

Abstract: Intravascular systems, devices, and methods having a captively-held filling are provided. An intravascular imaging device can include a flexible elongate member including a lumen having a proximal portion and a distal portion; a drive cable disposed within the lumen such that an ultrasound transducer coupled to the drive cable is positioned within the distal portion of the lumen; and a filling captively held within at least the distal portion of the lumen and surrounding the ultrasound transducer, the filling facilitating transmission and receipt of ultrasound signals. A method of manufacturing an intravascular imaging device can include acquiring a flexible elongate member including a lumen; inserting a drive cable into the lumen, a rotational ultrasound transducer being coupled to the drive cable; inserting a filling that facilitates transmission and receipt of ultrasonic signals into the lumen such that the filling surrounds rotational ultrasound transducer; and sealing the filling within the lumen.

Abstract: Disclosed is an intraluminal catheter that includes a flexible elongate shaft configured to be positioned within a body lumen of a patient, and an intraluminal sensor disposed at the distal portion of the shaft that is configured to sense a characteristic within the body lumen. The shaft further comprises a plurality of wires disposed around a lumen, wherein the wires are helically twisted. The wires can be helically twisted in a single direction to form a cylindrical shape. This helical structure is configured to stiffen the flexible elongate shaft for movement into an obstruction within the body lumen without kinking.

Abstract: An endoluminal filter including a first support member having a first end and a second end and a second support member attached to the first end of the first support member or the second end of the first support member and forming a crossover with the first support member. The endoluminal filter also includes a material capture structure extending between the first and second support members, the crossover and the first end or the second end of the first support member and at least one tissue anchor on the first support member or the second support member. The material capture structure can be formed by, for example, joining intersecting filaments, laser cutting a sheet of material, or additive manufacturing. A perimeter of the material capture structure can include attachments to join the material capture structure to the first or second support member.

Abstract: The invention generally relates to treatment of fistulas and abscesses and specifically to an all-in-one treatment device. The invention provides an aspiration catheter with imaging capabilities that can also deploy a blocking device, thereby providing an all-in-one treatment device for treating a fistula or an abscess. The device is inserted into an abscess and its imaging capabilities can be used to guide the device to a treatment site. A clogging device can be deployed from the device to prevent draining into, or out of, the abscess. In certain aspects, the invention provides a device for aspirating an abscess or fistula that includes a catheter having an extended body with a lumen therein, an imaging device such as an ultrasonic transducer disposed at a distal portion of the catheter, and a clogging device deployable from the catheter.

Abstract: The invention generally relates to devices and methods that provide for guided delivery of a heart replacement valve or other implant into the vasculature. In certain embodiments, a delivery device of the invention includes an outer sheath and an inner sheath moveably disposed within the outer sheath. The outer sheath includes a first imaging element and defining a center lumen that leads to an opening. The outer sheath is further configured to releasably hold an implant within the center lumen. The first imaging element is configured to at least partially surround the center lumen such that the implant is deployable through the first imaging element. The inner sheath is configured to engage with and deploy the implant out of the opening of the elongate body and into a body lumen.
