A tissue removal device includes a housing, an outer tube having a distal portion configured for transcervical insertion into a uterus, an inner tube slidably disposed within the outer tube lumen, a vacuum generation chamber disposed within the housing, a movable piston slidably disposed in the vacuum generation chamber, a collection chamber, a manual actuator moveably coupled to the housing and operatively coupled to the piston, and proximal and distal one-way valves. The outer tube has an outer tube lumen, a tissue in-take opening proximate a distal end thereof, and a proximal end coupled to the housing. The inner tube has an inner tube lumen extending from an open inner tube distal end to an open inner tube proximal end, the open inner tube distal end comprising a cutting edge configured to sever intrauterine tissue extending through the tissue in-take opening in the outer tube.

Tissue removal system

A uterine fibroid tissue removal device includes an inner tube disposed within an outer tube and configured to be translated and rotated relative to the outer tube, and a separately formed unitary distal tip member attached to a distal end of the inner tube, such that the distal tip member translates and rotates relative to the outer tube along with the inner tube, wherein a distal facing open cutting end of the distal tip member in fluid communication with an axial lumen of the distal tip member translates across a tissue resection window in a sidewall of the outer tube so as to sever tissue extending therethrough, the distal tip member axial lumen being in fluid communication with an axial lumen of the inner tube, wherein an outer diameter of the distal tip member is greater than an outer diameter of the inner tube.

Uterine fibroid tissue removal device

An endoscopic clip apparatus includes a clip sleeve defining an interior passage along a longitudinal axis and having a distal end with a plurality of openings defined in the distal end. A clip including a plurality of arms is disposed in the clip sleeve, and each arm includes a distal tip extending from the clip sleeve through one of the plurality of openings. Each arm includes a convex curved section oriented away from the longitudinal axis. The clip sleeve and clip are axially moveable relative to each other such that when the clip sleeve travels over the convex curved section of each arm toward the distal tip of each arm, each arm is constrained by the clip sleeve and each distal tip advances toward the longitudinal axis to grasp tissue.

Endoscopic clip apparatus and methods

A tissue removal device includes an outer tubular member coupled to a housing and a having a tissue resection window, an inner tubular member slidably disposed within the outer tubular member, a tissue trap having a sealed interior in fluid communication with a vacuum chamber, an open proximal end of the inner tubular member being disposed within the tissue trap interior, and an actuator moveably coupled to the housing and operatively connected to a movable piston in the vacuum chamber, such that movement of the actuator relative to the housing generates a vacuum in the tissue trap.

An apparatus for applying clips to tissue, comprises a plurality of clips, each of the clips including a proximal end having a pair of opposed jaws and a distal end including a linking feature, where the clips are linked to one another to form a clip chain with a linking feature of a distal-most one of the clips being gripped between the jaws of an immediately proximal one of the clips and a control linkage coupled to a proximal-most one of the clips for applying tension and compression to the clip chain in combination with a magazine containing the clip chain, the magazine including an abutment surface sized to prevent passage distally therebeyond of a clip having received between its jaws a linking feature of an immediately distal clip and an opening location within which the jaws of a clip are permitted to open to release a linking feature therefrom.

Endoscopic hemostatic clipping apparatus

An apparatus for applying clips to tissue, comprises a plurality of clips, each of the clips including a proximal end having a pair of opposed jaws and a distal and including a linking feature, where the clips are linked to one another to form a clip chain with a linking feature of a distal-most one of the clips being gripped between the jaws of an immediately proximal one of the clips and a control linkage coupled to a proximal-most one of the clips for applying tension and compression to the clip chain in combination with a magazine containing the clip chain, the magazine including an abutment surface sized to prevent passage distally therebeyond of a clip having received between its jaws a linking feature of an immediately distal clip and an opening location within which the jaws of a clip are permitted to open to release a linking feature therefrom.

A tissue removal system includes a morcellator having a cannula comprising a proximal end portion, a distal end portion, a sidewall, and at least one lumen extending between the proximal end portion and the distal end portion. A cutting blade is disposed within a lumen of the cannula. Also included is a tissue shield that has an expandable frame element and a shield element attached to the expandable frame element, wherein the tissue shield serves to isolate non-target tissues from at least the cutting blade of the system so that such tissues remain unaffected by a surgical procedure conducted with the system.

Surgical system with expandable shield

Endoscopic devices and methods used for fastening multiple tissue layers, such as, for example, an endoscopic fundoplication procedure, are disclosed. The device may include, for example, an elongated tubular member having a proximal end for extending outside of the body and a distal end for positioning proximate the multiple tissue layers, a grasper configured for positioning proximate the distal end of the tubular member and for grasping at least one of the multiple tissue layers, a device coupled to the distal end of the tubular member for folding the multiple tissue layers together, a tissue fastener configured to be inserted into the tissue layers to hold the tissue layers together, and a fastener head for inserting the tissue fastener into the tissue layers.
