Apparatus and methods for loading suture

Various embodiments of a cartridge for loading a suture onto a suturing instrument are disclosed. In some embodiments, the cartridge is operable 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. In some embodiments, the cartridge comprises a housing defining a chamber, and a partially pre-tied knot mounted about the housing or the chamber. The cartridge additionally provides a base coupled to the housing, the base defining a seat for releasably holding a portion of a suture to be aligned with, and transferred to, the suturing instrument. The portion of the suture may be held independently, or it may be coupled to a component such as a ferrule or shuttle.

SYSTEMS AND METHODS FOR ALTERING THE SHAPE OF NASAL TISSUES

Systems and methods are provided for altering the shape of a target tissue structure of a subject, e.g., a nasal septum or other nasal tissue that include securing a first end of a shaping element to tissue adjacent the structure; manipulating the tissue to alter a shape of the structure; and applying a force to the shaping element to maintain the altered shape of the structure.

Devices and methods for reshaping blood vessels

Veins and other blood vessels may be reshaped by introducing an implant through the vessel walls with anchors positioned on opposite sides of the wall. The anchors typically include an elongate body having coils or other anchors formed therein. The implants may be delivered percutaneously using a cannula which can hold the anchor externally or internally. The methods and devices are useful in treating a dorsal vein to reduce blood flow in patients suffering from erectile dysfunction.

TISSUE FIXATION DEVICES AND A TRANSORAL ENDOSCOPIC GASTROESOPHAGEAL FLAP VALVE RESTORATION DEVICE AND ASSEMBLY USING SAME

Tissue fasteners carried on a tissue piercing deployment wire fasten tissue layers of a mammalian body together. The fasteners include a first member, a second member, and a connecting member extending between the first and second members. The first and second members are substantially parallel to each other. The fasteners may be deployed in limited spaces and in various applications including the restoration of a gastroesophageal flap valve.

Insertion instrument for anchor assembly

An insertion instrument is configured to eject at least one anchor body into respective target locations, and subsequently apply a predetermined tensile force at least one actuation member of the at least one anchor member so as to actuate the at least one anchor body from a first configuration to a second expanded configuration. The insertion instrument can include a tension assembly that applies the predetermined tensile force to the at least one actuation member. The predetermined tensile force can be defined by a distance of travel, a predetermined failure force of a fuse, or a combination of distance of travel and a predetermined failure force of a fuse.

Method and apparatus for coupling anatomical features

A method of coupling a first portion of an anatomy to a second portion of the anatomy includes coupling first and second bones of the anatomy with a bone-tendon-bone implant. The bone-tendon-bone implant has a first bone end, a second bone end and a replacement tendon between the first and second bone ends. The first and second bone ends are positioned in corresponding first and second bores of the first and second bones. The first bone end is secured to the first bone with a first bone anchor. A second anchor coupled to the bone-tendon-bone implant is passed through and outside the second bore. The second anchor is coupled to an adjustable suture construct having two adjustable suture loops. Tensioning at least one of first and second ends of the adjustable suture construct tensions the replacement tendon and positions the first bone relative to the second bone.

A tissue anchor delivery device includes a handle, an elongate shaft extending from the handle, a pusher tube disposed at least partially within a lumen of the elongate shaft, a pusher hub coupled to the pusher tube, a needle disposed at least partially within a lumen of the pusher tube, a needle hub coupled to the needle, and an actuator configured to be fixed to the pusher hub and the needle hub. The actuator is further configured to advance the needle hub and the pusher hub a first distance, thereby causing a tip of the needle to protrude from a distal end of the elongate shaft, disengage from the needle hub, and advance the pusher hub a second distance relative to the needle hub, thereby causing a distal end of the pusher tube to advance over the needle and push a coiled suture form off of the needle.

DEVICES, SYSTEMS AND METHODS FOR TREATING BENIGN PROSTATIC HYPERPLASIA AND OTHER CONDITIONS

Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).

Apparatus and methods for minimally invasive transapical access
11751995 · 2023-09-12 · ·

A delivery catheter system includes an anchor catheter, a collapsible and expandable anchor, a balloon catheter, and a needle. The anchor may be for anchoring a prosthetic heart valve in a native heart valve. The anchor may be configured to be received within the anchor catheter. The balloon catheter may be positioned radially inward of the anchor catheter, and may include an inflatable balloon at a distal end thereof. The balloon may be in fluid communication with the balloon catheter. The needle may be positioned radially inward of the balloon catheter and may be translatable relative to the balloon, the needle having a sharp distal tip.

Devices and methods for percutaneous tricuspid valve repair

A first end of a wire is transluminally advanced to a location adjacent an atrium of a heart of a subject, while a second end of the wire remains disposed outside of the subject. From the location, the first end of the wire is penetrated through tissue into the atrium. A capture device is transluminally advanced into the atrium. Using the capture device, the first end of the wire is captured and pulled out of the subject. From the first end of the wire, a first anchor is tracked along the wire into the atrium, and is anchored to an annulus of a valve of the heart. A second anchor is advanced into the atrium, and is anchored to the annulus. Subsequently, the annulus is reshaped by applying tension between the first and second anchors.
