A surgical suture is caught in a needle tip that is pierced through a body tissue; and when the needle is withdrawn, the surgical suture is pulled out along a path through which the needle was pierced into the tissue, and the surgical suture is tied outside a patient's body. The surgical suture for the laparoscopic port site closure device, wherein the laparoscopic port site closure device is in a tube shape for being introduced into a port site, includes: a tubular body provided with needle guides that face each other and guide insertion of a needle; wings mounted to a lower portion of the tubular body such that the wings are opened and closed through a cam method; and an operating stick penetrating through the tubular body to operate the wings to be opened and to be closed.

An apparatus is provided for use in a medical procedure for stabilizing a target during approach of the apparatus towards the target. The apparatus comprises a body having a proximal end and a distal end, the distal end having a cavity formed therein, and a advanceable tip housed within the cavity. The advanceable tip is advanceable to engage a surface of the target.

A medical instrument, which is capable of holding a wire, includes: a sheath which has a center axis in a longitudinal direction from a distal end toward a proximal end thereof and includes in a distal end surface of the distal end a first contact area capable of being in contact with the wire and a second contact area coming in contact with the wire and provided on a proximal end side beyond the distal end with respect to the first contact area; and a holding portion which is advanceable and retractable in a lumen of the sheath and is retracted into the lumen of the sheath so that the wire is pressed to the first contact area and the second contact area and the holding portion holds the wire.

A lead puncture needle includes a core rod, a puncture needle, a lead mechanism and a handle. A front end of the core rod includes a blunt head and a lead slot. During puncture, the puncture needle is exposed. After the puncture, the blunt head protrudes out of the puncture needle to avoid injury to normal tissue. When a button is pressed, the core rod moves downward, and the lead slot protrudes from the puncture needle. When the button is pressed again, the core rod moves upward, and the lead slot is retracted into the puncture needle to form traction on a surgical suture. The design of the blunt head ensures that it is retracted during puncture to expose the puncture needle to facilitate puncture and the blunt head is controlled to be exposed outside the puncture needle in a separation process, thereby avoiding accidental injury to the surrounding tissue.

The present invention relates to a single-use, disposable, tissue suspender device comprising a longitudinal body having a distal end and a proximal end, the thickness of the body being substantially constant along a major portion of the length of said body from said proximal end towards said distal end; wherein a region immediately preceding the distal end of the body presents a reduced thickness compared to the remainder of the longitudinal body extending back toward the proximal end; and wherein the distal end comprises a distal bar attached to the region of reduced thickness of the longitudinal body which adopts an unconstrained deviating angle to a longitudinal axis of the longitudinal body. The invention also relates to use of the device for suspending tissue in a human or animal body.

A distal cap apparatus for use with an endoscope, having a proximal end and a distal end and a longitudinal axis extending therebetween, includes a mount configured for mounting to the distal end of the endoscope, and a strap connected to the mount and configured for banding about the distal end of the endoscope when the distal end of the endoscope is received in the mount. The mount defines a strap slot configured to receive an end of the strap to configure the strap in the banded configuration. The strap may be elastic. The strap may be a continuous band. In one embodiment, a distal cap apparatus includes a mount having a strap and a buckle for adjusting a size of a loop formed at least partially by the strap about the distal end of the endoscope.

A medical instrument is that the first holding portion or the second holding portion is capable of moving so that a distance between a distal end of the first holding portion and a distal end of the second holding portion changes from a first dimension which is larger than a diameter of the wire to a second dimension which is smaller than the diameter of the wire and the space is formed by the first holding portion and the second holding portion such that the wire is capable of rotating about a line connecting a first contact point where the first protrusion portion contacts with the wire with a second contact point where the second protrusion portion contacts with the wire.

One embodiment is directed to a system for closing a wound created at least partially across a tissue structure wall, comprising: a helical needle; a suture member coupled to the helical needle and configured to be pulled along a helical pattern with helical movement of the helical needle; an outer delivery member rotatably coupled to the helical needle; a drive shaft axially movably coupled to the outer delivery member; and a plurality of suture guide struts projecting distally from the outer delivery member; wherein upon helical insertion of the helical needle relative to the outer delivery member, the helical needle is advanced such that it becomes disposed around the guide struts, such that the guide struts prevent radial migration of the suture as it is helically wound into the tissue structure.

A surgical instrument can manipulate and pass suture through tissue. The device can easily pass suture through tissue with the suture fixed to the mechanism or where the suture is captured by the mechanism and allowed to slide. Along with this ability to control suture in one of two ways is a feature to provide a large amount of suture on the other side of the tissue that will be relatively easy for the surgeon to grab and pull out of the arthroscopic portal. The device includes a handle with a hollow shaft extending therefrom and a set of fingers movable into and out of the shaft. The fingers can be designed to capture suture, permit the suture to slide while captured, and optionally hold the suture in the device.

There is provided a treatment method that is capable of reducing burden on a patient when a medical sheet is indwelled in the body of the patient. A treatment method includes an introduction of introducing a catheter, which has stored a medical sheet (e.g., a myocardial cell sheet), to a heart inside a living body, and an indwelling step of drawing the myocardial cell sheet from the catheter and indwelling the myocardial cell sheet in the heart.
