Abstract: A spring element for a contact force sensing medical catheter. The spring element includes a first ring, a second ring spaced apart from the first ring, a plurality of struts connecting the first ring to the second ring, and a plurality of interlocking features. The second ring and the first ring are coaxially aligned with a longitudinal axis of the spring element. The plurality of struts is configured to permit elastic, relative axial and radial displacement between the first ring and the second ring. The plurality of interlocking features is configured to limit the relative axial and radial displacement between the first ring and the second ring.

Abstract: The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to devices, systems, and methods for securing tissue, such as a tissue defect or wound resulting from an endoscopic procedure, e.g., an endoscopic mucosal resection or submucosal dissection procedure. In one example, a device for securing tissue may include a loop portion configured to be disposed about a distal end of a delivery device in a delivery configuration and configured to be secured about the tissue in a deployed configuration. A locking member may be disposed on the loop portion. A tether portion having a proximal end extendable proximally within the delivery device and a distal portion extending from the loop portion slidably through the locking member.

Abstract: Medical devices for applying a cinch to a suture and methods for making and using such devices are disclosed. An example medical device may include an elongated shaft including a proximal region and a distal region. The distal region may define a lumen having a lumen dimeter, and a distally facing end surface. The medical device may also include an outer cinch member defining a bore and having an outer surface defining a shoulder. An elongated inner shaft may extend through and be longitudinally movable within the lumen and the bore and including a distal end section. An inner cinch member may be engaged with the distal end section of the elongated inner shaft.

Abstract: A method for producing cardiomyocyte cells including implanting a substrate within a heart such that a first portion of the substrate is in physical contact with an endocardium and a second portion of the substrate is not in contact with the endocardium, maintaining the first portion of the substrate in contact with the endocardium for a time at least sufficient to form trabecular fibers extending between the endocardium and the second portion of the substrate, cutting away the trabecular fibers from the endocardium, cutting away the trabecular fibers from the substrate, and removing the trabecular fibers from the heart, wherein the trabecular fibers include cardiomyocyte cells.

Abstract: An atherectomy system includes an atherectomy burr having one or more blood flow enhancement features that permit an increased level of blood flow past the burr relative to a blood flow that would result absent the one or more flow enhancement features. A drive mechanism is adapted to rotatably actuate the atherectomy burr.

Abstract: An anchor and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The anchor assembly includes an anchor tip and an anchor body. The anchor tip has a blunt end that may be rounded or beaded, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The anchor body has first and second ends, tip tabs, retainers for removably retaining the anchor body relative to the needle holder arm, and a suture opening. The anchor tip is fixed relative to the anchor body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the anchor body and is fixed therein.
