    Abstract: An example medical device is disclosed. The medical device includes a catheter shaft including a distal end portion, wherein the distal end portion includes an ablation assembly. The ablation assembly includes an expandable frame including a base, an end region and a plurality of struts extending between the base and the end region, the struts defining a plurality of apertures along the frame. The ablation assembly also includes an electrical circuit coupled to an inner surface of the second end region of the frame, the electrical circuit including a plurality of ablation electrodes coupled thereto. Further, the expandable frame is designed to shift from a delivery configuration in which the ablation electrodes face inward from the inner surface of the expandable frame to an expanded configuration in which the ablation electrodes face away from the base of the expandable frame.

    Abstract: A medical stent includes an elongate tubular body extending from a proximal end region to a distal end region. The distal end region of the elongate tubular body may be adapted to resist migration as a result of peristaltic force. The distal end region of the elongate tubular body may include two or more longitudinally-extending voids and two or more longitudinally-extending dynamic engagement features that are defined between adjacent longitudinally-extending voids. The two or more longitudinally-extending dynamic engagement features are adapted to splay radially outwardly in response to an applied peristaltic force, thereby dissipating the applied peristaltic force.

    Abstract: A debris removal system includes an elongated shaft extending from a proximal end to a distal end and including a shaft lumen, the shaft being configured to be inserted through a bodily lumen to a target surgical site, a vibration motor coupled to the elongated shaft via a vibration collar, the vibration motor including a rotatable shaft and at least one weight coupled to the rotatable shaft, the weight being asymmetrically shaped about a central axis of the shaft such that rotation of the shaft creates vibrational energy along the length of the elongated shaft to dislodge debris within the target surgical site, and a vacuum pump connected to the elongated shaft and configured to vacuum dislodged debris from the target surgical site through the shaft lumen.

    Abstract: In some aspects, the present disclosure pertains to a polymer that comprises a plurality of polymer arms, wherein a first portion of the polymer arms comprise a reactive end group and wherein a second portion of the polymer arms comprise a branched end group that comprise a plurality of covalently attached diagnostic and/or therapeutic groups, which may be, for example, radiocontrast groups or radioactive groups. Other aspects pertain to a system that comprises (a) a first composition comprising such a polymer and (b) a second composition comprising a multifunctional compound that comprises reactive functional groups that are reactive with the reactive end group of the multi-arm polymer. Still other aspects pertain to a crosslinked reaction product of (a) such a polymer and (b) a multifunctional compound that comprises functional groups that are reactive with the reactive end group of the multi-arm polymer.

    Abstract: A support mechanism for a medical device may include an adjustable support that includes a plurality of elongate members movable relative to one another. The support mechanism may also include a bracket coupled to the adjustable support. The bracket may be adapted to be coupled to a first medical device that extends along a longitudinal axis. The support mechanism may also include an instrument holder that extends along a central axis. The instrument holder may be movably coupled to the bracket and adapted to be coupled to a second medical device. The bracket and the instrument holder may be oriented such that central axis of the instrument holder intersects the longitudinal axis at an angle.
