Medical device for constricting tissue or a bodily orifice, for example a mitral valve
A medical apparatus positionable in a cavity of a bodily organ (e.g., a heart) may constrict a bodily orifice (e.g., a mitral valve). The medical apparatus may include tissue anchors that are implanted in the annulus of the orifice. The tissue anchors may be guided into position by an intravascularly or percutaneously deployed anchor guiding frame. Constriction of the orifice may be accomplished by cinching a flexible cable attached to implanted tissue anchors. The medical device may be used to approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.
Stitch lock for attaching two or more structures
An anchor assembly can include at least one anchor member, such as a pair of anchor members that are configured to be implanted in a target anatomical location in a first configuration, and can subsequently be actuated to an expanded configuration that secures the anchor members in the target anatomy. The anchor assembly can further include a connector member configured as a stitch lock that attaches the pair of anchor members together across a gap so as to approximate the anatomical defect.
NEEDLE AND GUIDE APPARATUS FOR PASSING SUTURE
A trocar wound closure system includes a suture passing needle and a guide for directing the needle through the wound site. A distal portion of the needle includes a capture rod with a slot. An obturator tube with a cutout section can be axially actuated to align the cutout section with the slot, and then moved out of alignment so as to capture the suture. The guide includes at least two tracks for directing the needle through the tissue track. A suture catcher is located adjacent to the exit of each track, and configured to be actuated from a radially extended configuration to a retracted configuration so as to capture the suture section inserted through each loop. Radially expandable arms at distal section are movable between an expanded configuration and a slender configuration.
Knotless suture anchors and methods of tissue repair
Systems and methods for soft tissue to bone repairs employing tensionable knotless anchors, without knot tying. The tensionable knotless anchors may be used by themselves or in combination with additional constructs (which may have a similar or different configuration, i.e., modified according to the specific repair) and with the flexible strands provided through tissue, around tissue, or through and around tissue to be repaired or fixated. The tensionable knotless anchors may be used to achieve simple stitch repairs, mattress stitch repairs or interlocked looped mattress repairs, among others. The tensionable knotless anchors may be also provided in a daisy chain configuration, i.e., with the suture from one anchor passed through the eyelet/loop of the shuttle/pull device of another anchor and repeated in a pattern.
Laparoscopic surgical instrument
The object of the present invention is to provide an improved laparoscopic, surgical instrument, particularly though not exclusively for gynaecology and in particular for Laparoscopic Colposuspension. According to the invention there is provided a laparoscopic, surgical instrument having an elongate shank, a ball head on one end and an eye in the other end. The instrument is such that the ball head is of a larger diameter than that of the elongate shank.
Method and system for orthopedic repair
An implantable orthopedic repair device includes an implant body having a rigid tubular shape which defines an inner lumen and an orthogonal suture side hole in communication with the inner lumen. The implantable orthopedic repair device includes a tension assembly that is supported by the inner lumen and suture side hole of the implant body. The tension assembly includes a suture loop which defines a suture tail and a sliding knot that when tensioned contracts at least one bone anchor, independent of the implant body, unidirectionally towards the implant body.
Sternal closure cerclage, plate implant and instrumentation
A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.
Truncated cone heart valve stent
A heart valve stent having a section with a heart valve implant and several proximally disposed tissue anchors, also comprising a plurality of anchoring threats, each with a proximate end fastened to the stent or valve and a distal end attached to tissue within a heart chamber to provide tension between the heart chamber tissue and the stent.
System for providing surgical access
One embodiment is directed to a system for closing a wound created at least partially across a tissue structure wall, comprising: a helical needle; a suture member coupled to the helical needle and configured to be pulled along a helical pattern with helical movement of the helical needle; an outer delivery member rotatably coupled to the helical needle; a drive shaft axially movably coupled to the outer delivery member; and a plurality of suture guide struts projecting distally from the outer delivery member; wherein upon helical insertion of the helical needle relative to the outer delivery member, the helical needle is advanced such that it becomes disposed around the guide struts, such that the guide struts prevent radial migration of the suture as it is helically wound into the tissue structure.
INTERNAL FIBULA SLING
Syndesmotic fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an ankle joint between a tibia and a fibula may include first and second anchors secured to the tibia and a suture configured to wrap around the fibula. The suture may be tensioned to provide a circumferential force around the fibula to stabilize the joint.
