A filament implant system including an insertion needle including an elongated body defining a longitudinal axis and having a distal end and a proximal end, the distal end of the elongated body including a penetrating tip, and a filament releasably connected to the insertion needle such that the filament is engaged with the insertion needle when the insertion needle is advanced into tissue distally along the longitudinal axis and the filament is disengaged from the insertion needle when the insertion needle is withdrawn from the tissue proximally along the longitudinal axis.

Filament implant system and method

A set of fenestration burrs, for fenestrating otic capsule bone (), includes an initial burr () and a sequence of fenestration polishing burrs (). A polishing burr (), of each of the burrs (), carries at least one spiraling flute ('). Fenestrations () piercing the bone () formed using the burrs () exhibit uniform diameters while excluding bone dust from the inner ear. An implantable casing () includes a hollow collar () from which projects a hollow sleeve () receivable into the fenestration (). The casing () is secured there by at least one prong () jutting from the sleeve (). A therapeutic appliance () is insertable into the casing (). A flange () extending from one end of the sleeve () carries at least one L-shaped slot () open at one end and extending circumferentially around the flange ().

Implantable therapeutic appliance for the cochlea

An assembly for releasably attaching a buttress material onto a tissue clamping member of a surgical stapling device is disclosed. The assembly has a substantially rigid frame for connecting to a top surface of a tissue clamping member of a surgical stapling device when the assembly is disposed thereon. A buttress material is attached to first and second sides of the frame for abutting against a bottom surface of a tissue clamping member of a surgical stapling device when the assembly is disposed thereon.

Device for attachment of buttress material to a surgical fastening device

A surgical stapling instrument for clamping and stapling tissue. The instrument has a handle and first and a second opposed tissue clamping members connected to the handle. The members are movable between an open position for receiving tissue therebetween and a closed position for stapling tissue therebetween. At least one of the first and second clamping members houses a plurality of staples. The device also includes a strip of buttress material releasably attached to at least one of the first and second tissue clamping members by a hot melt adhesive. The buttress material disposed on the clamping member such that the staples can attach the buttress material to tissue between the clamping members.

Adhesive for attaching buttress material to a surgical fastening device

A method for releasing buttress material from a stapling instrument when the buttress is attached to the instrument by an adhesive is disclosed. The method includes providing stapling instrument comprising first and a second opposed tissue clamping members movable between an open position, for receiving tissue therebetween, and a closed position for stapling tissue therebetween. At least one of the first and second clamping members houses a plurality of staples, and a strip of buttress material is releasably attached to the first tissue clamping member by an adhesive. The method then involves moving the instrument to its open position and inserting tissue between the clamping members. Thereafter, the method involves releasing the buttress material from attachment to the first clamping member by closing the instrument and stapling the buttress material to the tissue. Whereby the movement of the staples breaks the adhesive bond and releases the buttress material from the first clamping member.

Method for releasing buttress material attached to a surgical fastening device

A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a flexible support shaft to an actuator handle assembly. The support shaft is capable of bending in any radial direction relative to its centerline into a curved configuration suitable for insertion into a patient. The flexible support shaft includes a dual coil structure which is adapted to support itself in any curved configuration and to resist deflection upon insertion into the patient and actuation of the stapling head assembly. The stapling head assembly includes a driver assembly which is operable in multiple stages to separate the staple forming and tissue cutting actions to reduce the peak force required to operate the instrument. The actuator handle assembly includes a staple actuating lever and a cam follower assembly which operate in two stages with different mechanical advantages to facilitate the operation of the instrument by a surgeon. The actuator handle assembly includes a thumb wheel for opening and closing the anvil and an adjusting knob for adjusting the anvil gap. A control lever is provided for pivoting the stapling head assembly relative to the flexible support shaft.

A new method is shown whereby staples are closed to smaller heights so that virtually total hemostasis is possible. Also, the staple legs in alternate rows in the surgical stapler are made to interlock so that during closure, hemostasis is effected by the interlocking of the staple legs.

Surgical staple for insertion into tissue

A sealed surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. Various mechanisms for sealing the instrument are disclosed.

Circular anastomotic stapler with curved shaft

A surgical stapling instrument for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly mounted by a curved shaft to an actuator handle assembly and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil and staple driver of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar detachably secured by one or more retainer clips on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.
