TISSUE FASTENING

The fastener assemblies, systems, and methods of the present disclosure are generally directed to a first T-fastener and a second T-fastener securable to one another through the use of a suture extending therebetween and deliverable to an anatomical location using a minimally invasive technique. For example, a cannula of a needle assembly may be percutaneously deliverable to a treatment site and, through actuation of a hub of the needle assembly, the first T-fastener and the second T-fastener may be deliverable relative to biological tissue to be fastened at the treatment site. The suture may intracorporeally fasten the first T-fastener and the second T-fastener relative to one another for robust securement biological tissue therebetween. As compared to securement using external fixation, the fastener assemblies, systems, and methods of the present disclosure may facilitate intracorporeally fastening tissue while reducing or eliminating certain requirements associated with postoperative care.

Compressible adjuncts with drug release features

Compressible adjuncts for use with a staple cartridge are provided. In one exemplary embodiment, a compressible adjunct includes a non-fibrous adjunct material formed of at least one fused bioabsorbable polymer and configured to be releasably retained on a cartridge and configured to be delivered to tissue by deployment of staples in the cartridge. The adjunct material includes a lattice macrostructure having a plurality of drug delivery microstructures formed in the lattice macrostructure, in which each drug delivery microstructure has drug disposed therein. The plurality of drug delivery microstructures are configured to encapsulate the drug to thereby prevent drug release until the plurality of drug delivery microstructures are at least one of thermally ruptured while the adjunct material is stapled to tissue and mechanically ruptured in response to at least one of clamping, stapling, and cutting of the adjunct material. Stapling assemblies for use with a surgical stapler are also provided.

SURGICAL STAPLER WITH END EFFECTOR COATING

Methods and devices are provided for promoting wound healing. In general, surgical staplers and stapler components are provided having a coating thereon that is configured to selectively control an interaction between at least one matrix metalloproteinase (MMP) inhibitor and an outer surface of the stapler or stapler component.

DEVICES AND METHODS FOR EXCLUDING THE LEFT ATRIAL APPENDAGE

Devices and methods are described for occluding the left atrial appendage (LAA). The device excludes the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. The implantable device is delivered via transcatheter delivery into the LAA and secured within the LAA. The implant comprises an expandable and compliant frame and an expandable and conformable tubular foam body. The device may have a thromboresistant cover at a proximal end. The frame may have recapture struts inclining radially outwardly from a central hub. The frame may have axially extending side wall struts, with adjacent pairs of side wall struts joined at one or more apexes. Anchors extend from the frame and into the foam to engage tissue.

Intrathecal multifactorial infusion of heterogeneous autologous cell therapy
11464804 · 2022-10-11 ·

A method of treating spinal cord injuries in a patient using sagittal MR images of the spinal cord injury to guide the extent of exposure of the neuro/orthopedic surgeon during a posterior spinal fusion for the purpose of autologous stem cell therapy in the setting of spinal injury; the method using large volumes of the patient's bone marrow aspirated to yield a large quantity of heterogeneous autologous stem cell concentrate containing cellular and subcellular fractions, in addition to soluble protein factors (defined as heterogeneous concentrate) exhibiting regenerative potential which is then applied directly over the spinal cord (under the dura/arachnoid) in the areas affected.

SURGICAL INSTRUMENT WITH IMPROVED STOP/START CONTROL DURING A FIRING MOTION
20230108648 · 2023-04-06 ·

A surgical instrument. The surgical instrument includes an elongated channel, an anvil pivotably connected to the elongated channel, a closure member mechanically coupled to the anvil, an electric motor mechanically coupled to the closure member, a motor controller electrically coupled to the electric motor and a control circuit electrically connected to the motor controller. The control circuit is configured to monitor a first predefined event, monitor a second predefined event, provide a stop signal to the motor controller to stop a closing motion of at least one of the elongated channel and the anvil after an occurrence of the first predefined event, and provide a start signal to the motor controller to start the closing motion of the at least one of the elongated channel and the anvil after an occurrence of a second predefined event.

DEVICES AND METHODS FOR TISSUE REPAIR
20230104079 · 2023-04-06 ·

A tissue repair construct having first and second implants coupled via a flexible element is provided. The flexible element forms an adjustable loop closed with a sliding knot, and has first and second free ends extending from the knot formed by wrapping the second end around the first end. The second implant can have a changeable configuration. The construct can be placed within a surgical site in a patient's body such that the first implant is passed into a bone adjacent to soft tissue and the second implant is disposed on an opposed side of the soft tissue. The first free end of the flexible element is configured to be tensioned to decrease a size of the loop and thereby change the configuration of the second implant and to thereby cause at least the second implant to move towards the first implant.

A tissue thickness compensator may generally comprise a compressible core comprising a plurality of movable particles, and a wrap surrounding the compressible core. The plurality of movable particles may comprise at least one medicament. A tissue thickness compensator may generally comprise a compressible core comprising a plurality of crushable particles, and a wrap surrounding the compressible core. The plurality of crushable particles may comprise at least one medicament. The compressible core may comprise a material selected from a group consisting of a biocompatible material. The wrap may comprise a material selected from a group consisting of a biocompatible material. Articles of manufacture comprising the tissue thickness compensator and methods of making and using the tissue thickness compensator are also described.

MEDICAL IMPLANT, DELIVERY DEVICE, METHOD OF PRODUCING A MEDICAL IMPLANT, AND METHOD OF DELIVERING A MEDICAL IMPLANT

The invention relates to a medical implant (1) that is adapted to repair or close defect (D), in particular an opening in a ventricular, atrial, or septal wall (W). The medical implant (1) may, in particular, be a patch. It comprises an adhesive composition (6). It further comprises two states, wherein in the first state, the medical implant (1) can be deployed to an implant site while the adhesive composition (6) is inactive. It can be brought into a second state by an activation mechanism. The adhesive composition (6), in the second state, is curable by a curing mechanism.
