Abstract: A left atrial appendage closure device adapted for occluding the left atrial appendage includes a cone-shaped insert formed of an expandable foam and adapted for trans-septal delivery to the LAA. A polymeric covering is disposed over the cone-shaped insert, the polymeric covering adapted to protect the cone-shaped insert during trans-septal delivery to the LAA, the polymeric covering adapted for removal after trans-septal delivery to the LAA. An insert lumen extends through the cone-shaped insert prior to expansion of the cone-shaped insert. A tubular support rod extends through the insert lumen, the tubular support rod operably coupled with at least a portion of the polymeric covering, the tubular support rod itself defining a tubular support rod lumen adapted to accommodate a guidewire over which the insert may be advanced into the LAA and/or a radio frequency (RF) energy wire adapted for making a trans-septal puncture.

Abstract: Delivery devices for an occlusive implant and method for making and using delivery devices are disclosed. An example delivery device may include a delivery sheath having a proximal region, a garage region, and a distal tip region. The proximal region may have a proximal inner diameter. The garage region may have a garage inner diameter larger than the proximal inner diameter. A reinforcing member may extend along the proximal region, the garage region, or both. A core member may be slidably disposed within the delivery sheath. An occlusive implant releasably coupled to the core member.

Abstract: A medical assembly may comprise an end effector; a sheath; and a device coupler. The device coupler may include a proximal support, a distal support, and a coupler arm extending between the proximal support and the distal support. The coupler arm may include a surface configured to accommodate a shape of a medical device resting upon the coupler arm. The end effector may be attached to the distal support, and the proximal support may be attached to the sheath.

Abstract: A handle assembly includes a drive wire coupled to an expandable end effector, the wire having a diameter of no more than 3 French and a handle cannula receiving the wire therethrough, rotation of the handle cannula transferring torque to rotate the wire. The assembly also includes a shaft receiving the handle cannula, rotation of the shaft transferring torque to rotate the handle cannula. The assembly further includes an actuation assembly receiving the shaft, the actuation assembly coupled to a sheath sized to receive the wire and end effector therethrough, the actuation assembly moveable between a proximal configuration in which the sheath is moved proximally to expand the end effector and a distal configuration in which the sheath is moved distally to retract the end effector, the actuation assembly including a rotation mechanism transferring torque to the shaft to rotate the shaft.

Abstract: Devices and methods for deploying an anastomotic stent between portions of the gastro-intestinal (GI) tract are disclosed. The anastomotic stents are configured to atraumatically engage the tissue walls and to permit the flow of fluid, partially digested food, and food. The stents can be deployed using endoscopic catheter devices, laparoscopic tools, and combinations of both endoscopic tools and laparoscopic tools. Examples of anastomoses include anastomoses between the stomach and a portion of the intestines such as the jejunum. Anastomoses can also be formed between two closed ends of the intestines, such as two closed ends of the colon formed during a colon resection procedure. Anastomoses can also be formed between a fundal pouch formed during a gastric bypass procedure and the jejunum. Laparoscopic tools are disclosed to deploy a stent by selectively removing a radial restraint on a self expanding stent with the restraint removed through the laparoscopic access points.

Abstract: An implantable fluid operated device includes a fluid control system to transfer fluid between a fluid reservoir and an inflatable member. The fluid control system includes at least one fluid control device including at least one pump and at least one valve, or at least one combination pump and valve device. The at least one fluid control device includes an auxiliary fluid control device that maintains a closed state of the valve in response to a fluctuation in pressure, or a pressure spike that would otherwise cause an unintentional opening of the fluid control device, and unintentional flow of fluid through the fluid control device.

Abstract: Devices, systems, and methods for deploying a biliary stent. A biliary stent has lobes and creases to expand between contracted and expanded positions. The stent is delivered to a bile duct in a contracted position loaded on a shaft of a delivery device. When the shaft is retracted through the stent, wings on the shaft force the stent outward into the larger expanded position. In the expanded position, the creases form drainage channels to reduce blockage over the life of the stent.

Abstract: Medical devices and related methods useful for needle access during medical procedures are described. The medical device may include a needle and a handle coupled to the needle, wherein the handle includes a body comprising a radiolucent material, a first marker proximate a proximal end of the body and a second marker proximate a distal end of the body. Each of the first marker and the second marker may include a radiopaque material, and the first marker may have a shape complementary to the second marker to align a position of the needle relative to a subject when visualized by X-ray imaging.

Abstract: Devices, systems, and methods for a two-way valve assembly for a medical device. The two-way valve assembly has a knob seated within a valve body, two inlet passages leading to a suction source and a gas source, an outlet passage leading to an endoscope fluid channel, and an internal channel connecting one of the two inlet passages to the outlet passage. A spring presses the knob into the valve body to seal the openings along the channels and passages. Rotating the knob slides one or more guide pins on the knob along one or more guide grooves on the body and connects the other inlet passage to the outlet passage, such that the same endoscope fluid channel can be used both for suction, as in clearing fluid from within a patient, and delivering gas, as in insufflation.
