Patent number: 5971939Abstract: A needle biopsy device has a suction source, an inner cannula, and an outer cannula. The inner cannula has a biopsy reservoir formed proximate the distal end thereof and also has a lumen formed therein. The lumen provides fluid communication from the suction source to the biopsy reservoir. The outer cannula is slidably disposed about the inner cannula and has a cutter formed at the distal end thereof. The outer cannula has a distal position wherein it substantially covers the biopsy reservoir and has a proximate position wherein the biopsy reservoir is substantially exposed. An actuating mechanism moves the outer cannula from the distal position to the proximate position thereof, facilitates the application of suction from the suction source to the biopsy reservoir and moves the outer cannula from the proximate position to the distal position thereof.Type: GrantFiled: April 22, 1998Date of Patent: October 26, 1999Assignee: Laurus Medical CorporationInventors: Stephen A.

Patent number: 5741277Abstract: A method and device for the placement of sutures and for the purpose of approximating tissue. A particular utility is effected in the approximation of the tissue separated by means of an endosurgical trocar being inserted into a body cavity. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off.Type: GrantFiled: June 25, 1996Date of Patent: April 21, 1998Assignee: Laurus Medical CorporationInventors: Norman S.

Patent number: 5662664Abstract: A suturing device includes a shouldered surgical needle where the shoulder has a cross sectional transverse dimension. A suture is attached to a distal portion of the needle. A needle catch having a flexible aperture with a relaxed dimension which is smaller than the cross sectional transverse dimension of the shoulder allows insertion of the needle into the flexible aperture by expansion of the flexible aperture to a stretched dimension which is substantially equal to the cross sectional transverse dimension of the shoulder. The shoulder on the needle prevents removal of the needle from the flexible aperture in a direction which is the reverse of its direction of insertion into the flexible aperture.Type: GrantFiled: May 18, 1995Date of Patent: September 2, 1997Assignee: Laurus Medical CorporationInventors: Norman S.

Patent number: 5217114Abstract: A package for a catheter having a proximal end and a distal end, includes a tube defining a cavity along an elongate axis, the cavity being configured to receive at least the distal end of the catheter. Access means includes a housing fixed to the proximal end of the tube and a cap rotatable to engage the housing in a first position to seal the cavity, and to disengage the housing in a second position to provide access to the cavity. A circumferential tear-strip is configured and disposed to provide a high degree of control over the separation of the housing and cap. An O-ring, which forms a seal between the cap and housing, is disposed relative to a circumferential shoulder which cooperates with a camming surface to cause the cap to pop from the housing when rotated. An associated method includes the steps of rotating the cap a first angular distance to engage the camming surface and a second angular distance to cause the O-ring to traverse the shoulder.Type: GrantFiled: May 15, 1991Date of Patent: June 8, 1993Assignee: Applied Vascular Devices, Inc.Inventors: Donald L. Gadberry, Vincent C. Tangherlini, Robert P. Cooper

Patent number: 5209737Abstract: A septum valve in a trocar assembly has a variable orifice that is responsive to a cross-sectional dimension of the surgical instrument being inserted into the trocar channel, thereby minimizing leakage of inflation gas from the body cavity, such as the abdomen, being operated on. An elastomeric septum is disposed in the channel and includes portions which define an orifice having in a relaxed state a first cross-sectional area. An actuation assembly provided with levers which pivot radially outwardly to expand the seal and thereby expand the orifice to the second cross-sectional area in response to entry of the instrument into the channel. The actuation assembly is free to float in an annular recess to accommodate an instrument which is misaligned with the trocar channel.Type: GrantFiled: July 18, 1991Date of Patent: May 11, 1993Assignee: Applied Medical Resources, Inc.Inventors: Mark A. Ritchart, Robert P. Cooper, Charles C. Hart, Donald L. Gadberry

Patent number: 5127626Abstract: An apparatus is provided for sealing around shafts or tubes of varying diameter. Its basic element comprises an elastomeric sealing body with an axial passage which is radially compressed from more than two sides to compress the passage into sealing engagement with a member extending through the passage. Radial compression is achieved by cams and followers disposed around the body which cooperate with angularly spaced radially extending lugs formed integrally with the body. The cams are spring biased to normally compress the axial passage of the sealing body. Levers operable by one hand of the user are provided to selectively release the apparatus.Type: GrantFiled: October 2, 1990Date of Patent: July 7, 1992Assignee: Applied Vascular Devices, Inc.Inventors: Said S. Hilal, Robert P. Cooper, Donald L. Gadberry

Patent number: 5000049Abstract: An apparatus for measuring fluid pressure in a passage or tube for use with medical apparatus such as balloon catheters. A diaphragm gauge is provided and includes a case which houses a first diaphragm, a translation mechanism connected to the first diaphragm and a pointer attached to the translation mechanism for providing readouts of fluid pressure. The diaphragm is coupled to a fluid passage, such that changes in fluid pressure cause the diaphragm to activate the translation mechanism, thus providing readouts by means of the pointer. A second diaphragm is provided for sealing the fluid passage from the first diaphragm, for preventing transfer of materials between the first diaphragm and the passage. The second diaphragm is of a biocompatible, nonpyrogenic, sterlizable material, such a polyurethane, polyvinylchloride, or polyethylene. Alternatively, a biocompatible, nonpyrogenic coating may be provided on the first diaphragm for sealing it from the fluid passage.Type: GrantFiled: August 2, 1988Date of Patent: March 19, 1991Inventors: Robert P. Cooper, Said S. Hilal
