A forceps comprising a first jaw and a second jaw arranged along a longitudinal axis of the forceps for relative movement toward and away from one another. The first and second forceps jaws have respective first and second jaw surfaces facing each other. The first and second jaw surfaces have a serrated surface texture at least on a distal part thereof. A serration direction of the serrated surface texture is at an angle which is non-perpendicular to the longitudinal axis, resulting in additional profile structure elements at a tip portion surface, allowing to handle and manipulate fine tissue materials such as membranes in an eye.

A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.

Provided is an ophthalmic surgical instrument which can prevent curving of a pipe during a surgical procedure and can pull out a reinforcement sleeve by a required length such that the reinforcement sleeve covers the pipe. An ophthalmic surgical instrument (10) working in an eyeball includes a body portion (15) having a through-hole, a reinforcement sleeve (13) contacting an inner surface of the through-hole of the body portion (15), a pipe (12) passing through the inside of the reinforcement sleeve (13) and having a working portion (11) protruding from a tip end, and a movement member (17) connected to the pipe (12) and sliding in an axial direction of the ophthalmic surgical instrument to slide the pipe (12). A first slide mechanism allowing the reinforcement sleeve (13) to slide in the axial direction of the ophthalmic surgical instrument and a second slide mechanism allowing the pipe (12) to slide in the axial direction of the vitreous forceps are provided. Any one of the first and second slide mechanisms is an independent slide mechanism not influenced by the other slide mechanism.

A therapeutic instrument for the ergonomic, effective and safe opening and closing of targeted remote tissue sites; includes a pistol grip style handle with a hand activated lever for needle deployment and, optionally, with features to control tissue cutting and guide wire installation; also incorporates a specialized elongated rigid or flexible instrument shaft, which enables vacuum assisted holding of tissue at a uniquely contoured distal tip, where placement of a suture in a purse string configures occurs along with, if desired, tissue cutting and guide wire passage.

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end.
