TLDR
In this paper, the use of stress-induced martensite decreases the temperature sensitivity of the devices, thereby making them easier to install and/or remove, and thus reducing the cost.Abstract:
Medical devices which are currently proposed to use elements made from shape memory alloys may be improved by the use of stress-induced martensite alloy elements instead. The use of stress-induced martensite decreases the temperature sensitivity of the devices, thereby making them easier to install and/or remove.read more

Patent
Surgical instrument and method
TL;DR: In this paper, the authors describe a surgical instrument useful for laparoscopic surgery comprising an insulated shaft, a control means and a connection to an electrosurgical radiofrequency power source, its distal end having a tissue-engaging ledge, and the shaft supporting a tissueengaging clamping or cutting member movable toward the ledge in response to the control means so that an artery or other tissue in the pocket of the J-hook can be clamped or cut while radiofrequency current is applied.

Devices and methods for performing a vascular anastomosis
Hanson S. Gifford,Lee Bolduc,Jeffrey A. Stein,Paul C. Dicesare,Peter F. Costa,William A. Holmes +5 more
TL;DR: A vascular anastomosis staple is used in coronary artery bypass surgery as mentioned in this paper to create a leak-proof seal between a vascular graft and the ascending aorta in CABG surgery.
Patent
Articulating endoscopic surgical apparatus
TL;DR: In this article, a surgical instrument is provided for use in endoscopic or laparoscopic procedures, which includes a handle portion, an endoscopic portion extending from the handle, an articulating section pivotably connected to a distal end portion of the endoscopic part, and a retractor assembly operatively associated with the articulating part.
Patent
Apparatus and method for applying surgical staples to attach an object to body tissue
TL;DR: In this paper, an apparatus for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery is described, which includes a frame, and a generally elongated endoscopic section connected to the frame and extending distally therefrom.

Shape-memory surgical staple apparatus and method for use in surgical suturing
TL;DR: In this paper, a low-cost, lightweight surgical staple applicator utilizes a battery for heating the staples to produce closure, and is sterilizable by gamma radiation, but the applicator cannot be used for surgical suturing by simply positioning it in contact with the tissues to be sutured and heating it sufficiently to cause it to penetrate and clinch the tissues together.
Patent
Blood clot filter
TL;DR: In this paper, a blood clot filter is inserted into a collapsed configuration for insertion into a vein, and upon insertion automatically expands into a predetermined functional form which is in contact with the inner wall of the vein.

Vessel implantable appliance and method of implanting it
Ralph J Alfidi,William B Cross +1 more
TL;DR: An expansible appliance and methods of making and implanting it in a vessel of an animal was described in this paper, where a nickel-titanium alloy was initially formed in an expanded configuration and then deformed to a straight-line configuration for implantation.

Process for restoring patency to body vessels
Alexander Balko,Dhiraj M. Shah +1 more
TL;DR: In this paper, a shape memory alloy such as nitinol wire is used as an intra-luminal device to reinforce or replace a weakened or otherwise damaged vessel, which is inserted into the vessel in such a manner to be temperature insulated such that upon the removal of the insulation means, the wire reforms to its coil shape so as to be urged against the internal walls of the damaged vessel and supplies a patent channel through which body fluids may pass.
