  • Patent number: 11723649
    Abstract: A suture implant for approximating tissue without tying knots includes a suture having a first end with a fixed knot, a second end, and a slip knot located between the first and second ends, which defines a large suture loop having a length. The slip knot defines a dynamic end of the large suture loop that is located opposite a closed end of the large suture loop. A tissue anchor is coupled with the first end of the suture. Pulling the second end of the large suture loop away from the slip knot slides the slip knot and the tissue anchor toward the closed end of the large suture loop and reduces the length of the large suture loop. The suture implant includes a needle having a leading end and a trailing end and a small suture loop secured to the trailing end of the needle that is coupled with the closed end of the large suture loop.

  • Patent number: 11723680
    Abstract: Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

  • Patent number: 11617641
    Abstract: Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.

  • Patent number: 11612389
    Abstract: In one embodiment, a suture attachment catheter configured to repair a heart valve by inserting a suture in a valve leaflet of a beating heart of a patient includes a handle control, a flexible catheter body, and a suture attachment assembly at a distal end of the catheter body. The suture attachment assembly can include a rail between a distal clamping jaw hingedly attached to the rail, and a proximal clamping jaw. One of the proximal clamping jaw or distal clamping jaw can be selectively slideable with respect to the other on the rail using a jaw actuator of the control handle to adjust a distance between the proximal clamping jaw and the distal clamping jaw. A needle can be selectively slideable within the catheter body by using a needle actuator of the proximal handle control to penetrate a valve leaflet and insert a suture through the valve leaflet when the valve leaflet is captured between the proximal clamping jaw and the distal clamping jaw.

  • Patent number: 11602358
    Abstract: Examples of robotically controlled planar cutting systems and methods for controlling cutting systems to prepare bone tissue in surgical procedures, are generally described herein. Applicable surgical procedures for the robotically controlled cutting systems and methods include procedures involving the preparation (e.g., removal, surfacing) of bone tissue, such as is performed in knee arthroplasties. In an example, a robotically controlled planar cutting system can include a housing, a cutting element disposed in the housing, and a cutting control mechanism in communication with a robotic controller to control operation of the cutting element to machine a planar surface. The cutting element can be exposed and retracted relative to the housing and can include a plurality of cutting implements arranged to machine the planar surface.

  • Patent number: 11571238
    Abstract: An endarterectomy device configured to remove plaque from an occluded artery is disclosed. The endarterectomy device uses an adjustable wire loop end effector to establish and advance a dissection plane in the subadventitial space of the artery. The endarterectomy device is passed down the length of an artery in the subadventitial plane, adjusting the size of the wire loop end effector as needed to navigate the artery and dissect a plaque column, until the end of the plaque is reached. The wire loop end effector is then used as a plaque cutter to transect the distal end of the plaque column. The endarterectomy device is further configured along its length with support arms that facilitate removal of the plaque column as the device is removed from the artery.

  • Patent number: 11564684
    Abstract: A surgical instrument, operable to compress, staple, and cut tissue, includes a body, a shaft, and an end effector with a pair of jaws. A placement tip that is bent, angled, or curved and extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force, such as when the end effector is closed with the jaws in contact or when tissue is clamped between the jaws of the end effector. When the placement tip deflects, relative angles defined in part by the placement tip vary compared to an initial state without the clamping force. Furthermore, a distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force.
