    Abstract: Example medical devices are disclosed. An example medical device includes an elongate member having a proximal end region, a distal end region and an outer surface. The medical device also includes a plurality of filaments braided together in a first braided pattern along a first braided region of the elongate member, wherein the plurality of filaments extend continuously to a second braided region along the elongate member, wherein the plurality of filaments along the second braided region form a second braided pattern different from the first braided pattern.

    Abstract: The present disclosure relates generally to devices, systems, and methods for coil embolization, and, more particularly, to use and methods of forming coated coils. In an aspect, an embolic system may include a coil having a proximal end, a distal end, and a length therebetween slidingly disposed within a sheath. A coating may be disposed about the coil. A delivery filament may be configured to be slidingly disposed within the sheath proximal of the coil such that the coil can be ejected from the distal end of the sheath into the working lumen of a microcatheter. The coating may be configured to substantially fracture as the coil transitions from being substantially aligned with a longitudinal axis of the microcatheter to substantially misaligned with the longitudinal axis of the microcatheter upon being ejected from the microcatheter. The coating may be configured to plasticize after being ejected into an aqueous environment.

    Abstract: A hub assembly for connection to a medical device. The hub assembly may comprises an outer component having a proximal end, a distal end, and a cavity extending from the proximal end to the distal end. The hub assembly may further include an insert having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component. The insert may have a lumen extending from the proximal end to the distal end thereof. The outer component may be formed from a first material and the insert may be formed from a second material different from the first material.

    Abstract: Locking catheters including a fluid-tight hub and mechanism to secure a flexible member. An illustrative locking catheter may comprise an elongate shaft defining a lumen, a first connection member coupled to the elongate shaft, a second connection member configured to be releasably coupled to the first connection member, and a flexible member extending through at least a portion of a lumen of the elongate shaft and a portion of a lumen of the first connection member. The proximal end of the flexible member may extend through the aperture of the first connection member such that the proximal end of the flexible member is exterior to the first connection member. When the second connection member is coupled with the first connection member, the flexible member may be secured between an inner surface of the first connection member and an outer surface of the inner tubular member of the second connection member.

    Abstract: Medical devices, medical device systems, and methods for using the same are disclosed. An example medical device system may include a guide catheter having a proximal end, a distal end, and a lumen extending therebetween. The guide catheter may be designed to guide a therapeutic catheter to a target site. A guidewire may be disposed within the lumen of the guide catheter. The system may also include a trap balloon catheter including a catheter shaft and a balloon coupled to the catheter shaft. The trap balloon catheter may be designed to extend through the lumen of the guide catheter to a position adjacent to the distal end of the guide catheter. A trap balloon retainer may be coupled to the catheter shaft. The trap balloon retainer may be designed to prevent a distal end of the trap balloon catheter from extending distally beyond the distal end of the guide catheter.
