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

A medical device may include an expandable energy delivery array reciprocally movable between a first configuration and a second configuration. The expandable energy delivery array may include a first assembly having a first proximal end piece, a first distal end piece, and one or more first energy transfer elements extending between the first proximal and first distal end pieces, and a second assembly having a second proximal end piece, a second distal end piece, and one or more second energy transfer elements extending between the second proximal and second distal end pieces. The second proximal end piece may be proximal to the first proximal end piece and the second distal end piece may be distal to the first distal end piece.

Expandable catheter and related methods of manufacture and use

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 medical device is disclosed. The medical device may include an elongate member having a lumen extending at least partially between a proximal end and a distal end of the elongate member. The medical device may also include a plurality of legs coupled to a distal portion of the elongate member, and a distal end piece connected to each of the plurality of legs and located distally to the distal end of the elongate member. The medical device may also include an actuating member coupled to the distal end piece and extending between the plurality of legs and through the lumen. The reciprocal movement of the actuating member may be configured to reversibly move the plurality of legs from a first position to a second position. The medical device may also include a stopping member coupled to the actuating member and configured to limit a movement of the actuating member.

Devices for delivering energy and related methods of use

Embodiments of the disclosure are directed to a medical device. The medical device may include a shaft having a proximal end and a distal end. A positioning mechanism may be disposed adjacent the distal end of the shaft. The positioning mechanism may include an outer member and an inner member coupled to an end-effector. The outer member may be pivotably attached to the distal end of the shaft and the inner member may be pivotably attached to the outer member.

Medical devices with multiple degrees of freedom and related methods of use

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 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 the axial lumen of the distal tip member is smaller in cross-sectional area than the axial lumen of the inner tube, and wherein the distal tip member has a length greater than a length of the resection window.

Disclosed is a tubular cutting element for axial reciprocal movement within an outer tubular sleeve. The cutting element has an elongate tubular body, having a proximal end, a distal end and a cutting tip. The tubular body is formed in a drawing operation and the cutting tip is formed in a milling operation. The tubular body may have a Rockwell C hardness of no more than about 40, and the cutting tip may have a Rockwell C hardness of at least about 50.

Tissue cutter with differential hardness

A surgical access device can comprise a working channel providing a first lumen having an axial opening for insertion of a surgical instrument having an outflow channel, the first lumen having a fluid inlet for allowing fluid flow through the working channel and into the body, wherein fluid flows out of the body through the outflow channel of the surgical instrument; and a optical channel providing a second lumen for a visualization element and a light source, wherein the working channel comprises a larger cross-sectional area than the cross-sectional area of the optical channel. The surgical access device can further comprise a seal apparatus coupled to the working channel and configured to receive the surgical instrument, the seal apparatus comprising a first seal portion and a second seal portion, the first seal portion configured to close the fluid path into the seal apparatus, and the second seal portion configured to form a seal with the surgical instrument.

Access system with removable outflow channel

Disclosed are methods and devices for removing tissue from a site in a hollow organ, where the device has a low crossing profile and is capable of removing tissue at a high rate of speed. The device includes an elongate outer tube with a side opening and an inner tube moveably coaxially positioned within the outer tube. Tissue drawn into the side opening can be severed by moving the inner tube across the opening. Tissue may be removed through the device at a rate of at least about 1.4 cc per minute, through a lumen having a cross-sectional area of no greater than about 12.0mm. Cutting may be accomplished by rotating the inner tube at a speed of at least about 4000 rpm, and axially reciprocating the inner tube at a rate of at least about 1.5 cycles per second. The window may have a rho value of no more than about 1, and the outside diameter of the device may be no more than about 3 mm.
