The applicator instruments have a curved insertion needle.
Abstract:
본 발명은 초고분자량 폴리에틸렌 섬유(Fiber)와 이종(異種)의 유색 섬유(Fiber)를 꼬아 제조한 봉합사에 관한 것으로, 식별력이 현저히 향상되고, 또한 초고분자량 폴리에틸렌(UHMWPE)섬유의 배합량, 섬유들의 꼬임 각도 및 꼬임 간격을 최적화함으로써 직선 강력과 매듭 강력이 우수할 뿐만 아니라 매듭 안정성이 향상된 봉합사에 관한 것이다.
Abstract:
This disclosure concerns suburethral and pelvic support structures which utilize tissue soldering materials instead of, or in addition to, traditional tissue anchors and suture knots. It further concerns methods of treating patients that includes implanting these structures and activating the tissue soldering materials to attach the structures to a tissue in the body of the patient.
Abstract:
An apparatus and method is disclosed for securing tissue using an improved retention device. The apparatus and method is suitable for securing a suture to a bone or an anchor or securing a first tissue to a second tissue. The retention device is capable of attaching to a flexible member. The apparatus and method is appropriate for arthroscopic surgery.
Abstract:
The automated needle holder and suturing device comprises an arcuate jaw member(12) comprising a curvature such that the curvature is in correlation with the curvature of a curved needle(10) adapted to be used with the device. It also comprises a slotted guide(13), a rack and pinion assembly in order to engage and disengage the needle mover assembly(16), a piston element(24) adapted to be linearly slide-able and being triggered by at least a trigger assembly(35), a biasing element(26) coupled with the piston element(24), and a laterally located slotted profile(27) in order to guide at least a plunger(28). The biasing element(26) is linearly slide-able as well as angularly displaceable as per the piston element(24) movement. The operative distal end of said biasing element(26) is coupled with the rack element(22).
Abstract:
A medical device includes a surgical needle attached to a mesh suture having anti-roping elements. The suture is constructed of a macroporous mesh wall that facilitates and allows tissue integration subsequent to introduction to the body, thereby preventing suture pull-through and improving biocompatibility. Advantageously, the anti-roping elements serve to maintain the desired construct of the mesh wall when undergoing axial tensile loads by resisting elongation and loss of outer mesh wall macroporosity, while still permitting a flattening of the suture with lateral loading.
Abstract:
A method for repairing soft tissue. The method includes: forming a first bone hole; forming a second bone hole; connecting a first portion of the first bone hole to a second portion of the second bone hole to form a single bone bore; positioning at least a first anchor of a first suture construct at a distal end of the first bone hole, and positioning a second anchor of a second suture construct at a distal end of the second bone hole; connecting the first and the second suture constructs to the soft tissue; and drawing the soft tissue into the single bone bore with the first and the second suture constructs.
Abstract:
A tissue anchor system includes a support material, a suture engaged with the support material, an anchor, and an introducer. The anchor has a body, a fin extending from the body in a first direction with an eyelet formed in the fin, a pair of radial barrels extending from the body in a radial direction perpendicular to the first direction, and a gripping tab removably attached to the fin. The suture is engaged with the eyelet of the fin. The introducer has a cannula with a bore sized to receive the body of the anchor and a slot formed in a wall of the cannula. The slot is sized to receive the fin of the anchor, and an ejection mechanism provided to eject the anchor out of the cannula.
Abstract:
Il est proposé une base support (1") pour fil de suture présentant deux côtés opposés (12, 14) et comprenant sur un (12) de ses côtés un canal de retenue (2) d'un fil de suture dans une position enroulée, et une zone de parcage (4) d'une extrémité du fil de suture, la zone de parcage (4) étant entourée par le canal de retenue (2), la base support (1) étant caractérisé en ce qu'elle présente une ouverture traversante (5) entre ses deux côtés (12, 14), l'ouverture traversante (5) s'étendant dans la zone de parcage (4) et se prolongeant depuis la zone de parcage (4) de façon à couper le canal de retenue (2), et un volet (8) mobile entre une position ouverte pour dévoiler l'ouverture traversante (5) entre ses deux côtés (12, 14), et une position fermée pour boucher au moins en partie l'ouverture traversante (5), le volet mobile (8) étant configuré pour faire saillie, dans sa position ouverte, depuis le côté (14) de la base (1") qui est opposé au côté (12) sur lequel le canal de retenue (2) est formé.
Abstract:
A powder chitosan-based material can be used for biomedical applications. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan material. A single or multiple such treatments may be employed. For example, the chitosan material may be irradiated under nitrogen using γ-irradiation, treated under a nitrogen plasma, or both. A powder chitosan material can be readily treated by surface modifying treatments such as irradiating under nitrogen using γ- irradiation, treating under a nitrogen plasma, or both.
