Systems and devices for setting an anchor
An anchoring system and related methods are provided for treatment of dilated hearts and of functional valve regurgitation, the system comprising one or more self-expandable or manually expandable anchors and associated devices for fixating a valve splint within the heart. For example, a spade-shaped assembly may be configured to be deployed in a right ventricle of the heart and to stabilize a puncturing instrument to puncture the septum. Various puncturing instruments may also be part of the anchoring system, including one or more of a flexible needle having a multiplicity of slits disposed along the length of the needle, a trocar catheter with a retractable head, and a catheter needle having a blunt introducer to protect nearby tissue within the heart during advancing a guidewire. A cutter catheter and puncture location catheter may also be part of the system and be used during treatment.
Adjustable artificial chordae tendineae fixing assembly and an implanting method thereof
An adjustable artificial chordae tendineae fixing assembly includes an occlusion device and an adjusting rod which are both a hollow structure allowing the artificial chordae tendineae to pass through. The occlusion device is configured to be clamped on the interventricular septum. The occlusion device is provided with a switch adjusting device which controls the artificial chordae tendineae to move and to be fixed. The adjusting rod is connected to the occlusion device, and is capable of repeatedly adjusting the switch adjusting device on the occlusion device. The artificial chordae tendineae fixing assembly can fix the artificial chordae tendineae on the interventricular septum, and can also overcome the problem of unsuitable length of the artificial chordae tendineae in most of patients after the procedure due to cardiac changes. The artificial chordae tendineae is retained at the skin puncture point for a short time.
Apparatus and Methods for Loading Suture
Various embodiments of a cartridge are disclosed, for loading a suture onto a suturing instrument and, in some embodiments, for loading a pre-tied knot formed from the suture onto the suturing instrument. The suturing instrument is typically of the type having a suture passing member defining a suture receiving passage therein. The cartridge may be operable to load the suture and/or the knot onto the suturing instrument at a point of use. In some embodiments, the cartridge defines a path for insertion thereto and withdrawal therefrom of the suturing instrument. The cartridge further comprises a seat for releasably holding a portion of a suture and a mechanism for transferring the suture from seat to the suturing instrument, various features of which are described herein.
Method of using surgical device to deploy implants
This disclosure relates to a surgical method for deploying implants for repairing damaged tissue, such as meniscus tears. One exemplary surgical device for use in the method includes a cannula and a pusher moveable within the cannula to deploy a plurality of implants. Movement of the pusher in the distal direction deploys a distal-most implant and moves any additional implants distally within the cannula. Thus, multiple implants can be loaded into the cannula and deployed using one pusher. The disclosed arrangement is easy to use and has fewer component parts compared to prior devices, which in turn increases the ease of manufacture and reduces cost.
Apparatus and method for concurrently forming a gastroesophageal valve and tightening the lower esophageal sphincter
An apparatus enables concurrent restoration of a gastroesophageal valve and tightening of the lower esophageal sphincter. The apparatus comprises a longitudinal member having a distal end arranged to be received within a stomach, a tissue shaper at the distal end of the longitudinal member that forms a gastroesophageal valve from stomach tissue, and a tissue gatherer that gathers fundus tissue at or aboral to the gastroesophageal junction to reduce an esophageal opening into the stomach and tighten the lower esophageal sphincter. A fastener deployer then deploys at least one fastener pair to maintain both the restored gastroesophageal valve and the tightened lower esophageal sphincter.
DEVICES, SYSTEMS, AND METHODS FOR RESHAPING A HEART VALVE ANNULUS
Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the right atrium, which allow tricuspid valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant. The implants or systems of implants and methods may utilize a bridge stop to secure the implant.
Knotless syndesmosis system
A bone anchor includes a flexible strand defining a first adjustable loop and a friction knot coupled to a proximal end of the first adjustable loop. The friction knot is configured to allow adjustment of the first adjustable loop in a first configuration and is configured to prevent adjustment of the first adjustable loop in a second configuration. A knot capsule includes a body defining an internal knot cavity. The friction knot and a portion of the first adjustable loop are positioned within the internal knot cavity. The internal knot cavity defines one or more impingement surfaces configured to maintain the friction knot in a fixed position within the internal knot cavity when the friction knot is in the second configuration.
Tissue repair device
The present disclosure relates to a tissue repair device. The device includes a handle, a knob coupled to the handle, and a needle coupled to the handle. The needle includes a proximal end and a distal end, the distal end including a slot, wherein a first anchor is housed within the distal end and a second anchor is housed within the slot and located proximal to the first anchor. An actuator disposed within the needle and operatively coupled to the knob, wherein advancement of the knob allows for engagement of the actuator with the first anchor and subsequent advancement of the first anchor via the actuator. A method of tissue repair is also disclosed.
TISSUE REPAIR DEVICE
The present disclosure relates to a tissue repair device. The device includes a handle, a knob coupled to the handle, and a needle coupled to the handle. The needle includes a proximal end and a distal end, the distal end including a slot, wherein a first anchor is housed within the distal end and a second anchor is housed within the slot and located proximal to the first anchor, An actuator disposed within the needle and operatively coupled to the knob, wherein advancement of the knob allows for engagement of the actuator with the first anchor and subsequent advancement of the first anchor via the actuator. A method of tissue repair is also disclosed.
Heart tissue anchors
A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.
