What is disclosed are medical devices comprising a rounded, thin-walled, expandable metal structure (“ballstent”) and a flexible, elongated delivery device (“delivery catheter”) and systems and methods of use for treating saccular vascular aneurysms with the medical devices. Ballstents comprised of gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm, and expanded to conform to the shape of the aneurysm are disclosed. The external surface of ballstents can be configured to promote local thrombosis and to promote the growth of tissue into and around the wall of the ballstent in order to seal the aneurysm and fix the ballstent in place in the aneurysm. The wall of the ballstent can also be configured to release drugs or pharmacologically active molecules, such as those that promote thrombosis, cell proliferation, extracellular matrix deposition, and tissue growth.

The outer thread 120 is formed to be braided with multiple ultrafine threads 121, and covers an outer surface of the core thread 110. In the ultrafine thread 121, an outer-filament cover layer 122 made of MPC is formed on an outer surface of a filament 121a. The inner-filament cover layer 112 and the outer-filament cover layer 122 are respectively formed on the outer surfaces of the filaments 111a, 121a within a weight range of equal to or greater than 0.05% and less than 0.3% with respect to the total weight of each of the filaments 111a, 121a, respectively.

Systems, devices, and methods are provided for securing soft tissue to bone. One exemplary embodiment of a device includes an anchor, a repair filament, and a connecting filament that is coupled to the repair filament, is in contact with the anchor's distal end, and is effective to connect the repair filament to the anchor such that the repair filament slides with respect to the anchor. The anchor can be rigid, and can include an axial bore extending therethrough. At least one of the repair filament and the connecting filament can extend through at least a portion of the axial bore, and the bore can be sized such that a portion of the filament extending therethrough barely fits to help maintain the connection between the anchor, repair filament, and connecting filament. Embodiments of the systems and devices disclosed can be used in a number of methods for repairing soft tissue.

An apparatus for deployment of a hemostatic clip includes a handle assembly, a shaft connected to a distal portion thereof and a clip assembly releasably coupled to a distal portion of the shaft. The clip assembly includes clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly. In addition, the apparatus includes a control wire including a ball connector, the control wire extending from the handle assembly and coupled to the clip assembly by the ball connector to maintain the clip assembly coupled to the shaft, wherein the ball connector is detachable from the clip assembly to provide a second user feedback indicating separation of the clip assembly.

An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

Stapling devices and staple cartridges are disclosed. A stapling device can include a jaw configured to sequentially receive a plurality of dissimilar staple cartridges having different bioabsorbable components. An adjustment module can implement a firing control algorithm based on which dissimilar staple cartridge is received in the jaw. A staple cartridge can include staples comprised of a bioabsorbable metal alloy and configured to degrade at a staple degradation rate over an expected staple life in the patient. A staple cartridge can also include an implantable layer comprised of a bioabsorbable polymer and configured to degrade at a layer degradation rate over an expected layer life in the patient. The staple degradation rate and the implantable degradation rate can be different. The implantable layer can mechanically support at least a portion of a staple for a time in the expected staple life.

A method of pairing bioabsorbable staples in a staple cartridge with the tissue being treated such that the staples are structurally sufficient during the healing window of the tissue but completely bioabsorb shortly thereafter.

A non-pneumatic tourniquet including a tourniquet ring configured to resiliently constrict around a body part of a subject. The tourniquet ring defines a plurality of openings. A handle moves the tourniquet ring onto the body part and includes a first strap having a first end secured to the tourniquet ring at one of the openings and a second end secured to the tourniquet ring at one of the openings. A second strap has a first end secured to the tourniquet ring at one of the openings and a second end secured to the tourniquet ring at one of the openings.

In an aspect, a device includes a body structure including a core and a sleeve disposed around at least a portion of the core, the core defining a channel through the core extending from a first end of the core to a second end of the core, the sleeve including a flange adjacent the second end of the core; and a deployable portion coupled to the body structure adjacent the first end of the core, the deployable portion having a wired structure transitionable between a retained configuration and a deployed configuration, wherein a top portion of the wired structure extends beyond the first end of the core in a longitudinal direction when the wired structure is in the retained configuration, and wherein first end of the core extends beyond the top portion of the wired structure when the wired structure is in the deployed configuration.

Disclosed is a thrombectomy stent system, comprising a thrombectomy stent, wherein the thrombectomy stent is roll-shaped, and the cross section of the thrombectomy stent is of an open-ring structure. Disclosed is a thrombectomy device, comprising the thrombectomy stent, wherein the thrombectomy stent is provided with a developing element that can accurately display the expansion state of the thrombectomy stent during thrombectomy and the specific position of the thrombectomy stent so as to determine the situation of the thrombectomy stent being fused with a blood vessel. Disclosed is a thrombectomy device system, comprising the thrombectomy stent and a push rod, wherein a proximal end of the thrombectomy stent is connected to the push rod, and the proximal end of the thrombectomy stent or the push rod is connected to a catching member; and the catching member is configured to receive the thrombectomy stent.
