The present disclosure is directed to devices, kits, and methods for treating lumbar spinal stenosis by at least partially decompressing a compressed nerve root. The method can include identifying the compressed nerve root and percutaneously accessing a region of a lamina located adjacent to the compressed nerve root. The method can also include forming a channel through the region of the lamina, wherein the channel can be formed medial to a lateral border of the lamina. Further, the method can include expanding the channel in a lateral direction.

Embodiments of the present disclosure relate to a hollow needle configured to form a void in a membrane. An example hollow needle includes a tube body that extends along a tube axis between a first end and a second end, wherein the first end defines a tip of the tube body; and a hollow portion surrounded by the tube body, wherein the hollow portion comprises an opening in the tip. The tube body may comprise: a sharp portion provided at the tip; and a suction void connected to the hollow portion that may be fluidly connected to a suction device, wherein the hollow portion is configured to cause a negative pressure applied to the suction void to be applied through the opening. The application of the negative pressure through the opening may pull the membrane against the tip to cause the sharp portion to pierce the membrane.

Presented is a system and method for implanting a flexible electrode array in a biological organ. The system includes an electrode implant tool that includes an elongate rod and an electrode implant assembly having a plurality of attachment members. The electrode implant assembly further includes a ring member connected to each of the attachment members. A variable magnetic field generator is arranged in the ring member. The system uses electromagnetic force to temporarily strengthen the flexible electrodes allowing the penetration into the brain.

A surgical anchor delivery device includes a shaft, a plurality of anchors disposed within the shaft, and a threaded rod disposed within the shaft and threadably engaged with the anchors. Rotation of the threaded rod advances the anchors toward the distal end of the shaft without rotating the anchors relative to the shaft. The delivery device may include an actuation mechanism configured to rotate the threaded rod. A method of delivering the anchors may include advancing the distal end of the shaft to a first location, rotating the threaded rod to advance a first anchor out the distal end of the shaft without rotating the first anchor relative to the shaft, repositioning the distal end of the shaft to a second position, and rotating the threaded rod to advance a second anchor out the distal end of the shaft without rotating the second anchor relative to the shaft.

An occlusion device for occluding a left atrial appendage extending from a lateral wall of a left atrium of a heart including a first clamping portion and a second clamping portion movably connected to one another and configured for positioning along opposed sides of the left atrial appendage. The first clamping portion and the second clamping portion each may include an inner side configured to face toward the left atrial appendage when the device is in a deployed configuration, an outer side disposed opposite the inner side and configured to face away from the left atrial appendage when the device is in the deployed configuration. A pair of sleeves may be coupled to the outer side of each clamping portion. Each sleeve defines a channel configured to accept a medical tool to facilitate moving the device between an open and closed configuration.

Capture devices and related systems are described, including a medical device that includes a handle coupled to an end effector. The end effector may be formed from a first wire and a second wire each forming a coil. The coil of the first wire may be proximal to the coil of the second wire. The first wire and the second wire each include a shape memory material, such that the end effector includes a collapsed configuration when constrained within a sheath and an expanded configuration when unconstrained by the sheath. While in the expanded configuration, the first wire and the second wire may be movable relative to each other top provide a space, e.g., an opening, between the coil of the first wire and the coil of the second wire.

A breastfeeding system is provided. The breastfeeding system includes a breastfeeding collection and simulation device, which includes: one or more breast cover layers, wherein one or more of the layers are conformable to at least a portion of one or more breasts, wherein the layers are configured to interface with the breasts, and wherein one or more of the layers include one or more receptacle spaces into which liquid can flow; and one or more of simulation devices that each one or more of mimics and simulates breastfeeding and that is at least one of included in and associated with at least a portion of at least one of the breasts and of the layers, the one or more simulation devices configured to at least one of contact and interact with at least one of one or more of the layers and one or more of the breasts.
