Patent number: 6355014Abstract: Disclosed herein is a low profile catheter valve comprising a movable sealer portion positioned within the inflation lumen of a catheter. The sealer portion forms a fluid tight seal with the inflation lumen by firmly contacting the entire circumference of a section of the inflation lumen. The sealer portion may be positioned proximally of a side-access inflation port on the catheter, to establish an unrestricted fluid pathway between the inflation port and an inflatable balloon on the distal end of the catheter. As desired, the clinician may move the sealer portion to a position distal of the inflation port, thereby preventing any fluid from being introduced into or withdrawn from the balloon via the inflation port.Type: GrantFiled: March 13, 1998Date of Patent: March 12, 2002Assignee: Medtronic PercuSurge, Inc.Inventors: Gholam-Reza Zadno-Azizi, April A. Marano-Ford, Celso J. Bagaoisan, Jeffrey C. Bleam, Isaac J. Kim, Jeffrey F. Field

Patent number: 6293925Abstract: An insertion device and insertion set. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The carrier body is slidably received within the device housing for movement between an advanced position and a retracted position. The carrier body also includes a receiving structure to support the insertion set in a position with the at least one piercing member oriented for insertion through the skin of the patient at a predetermined angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position.Type: GrantFiled: December 18, 1998Date of Patent: September 25, 2001Assignee: MiniMed Inc.Inventors: Jason H. Safabash, Susan M. McConnell, Randy W. Adair, Jeffery V. Funderburk, April A. Marano, Jeffrey F. Field

Patent number: 6093172Abstract: An injector is provided for automatic placement of a subcutaneous insertion set such as an infusion set or the like used for delivering a selected medication to a patient. The injector comprises a spring-loaded plunger having a head for receiving and supporting the insertion set in a position for placement of a medical insertion needle through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the insertion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle. When the plunger head reaches a fully advanced position, with the insertion set placed on the patient, the insertion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector.Type: GrantFiled: December 31, 1997Date of Patent: July 25, 2000Assignee: MiniMed Inc.Inventors: Jeffery V. Funderburk, April A. Marano, Jeffrey F. Field

Patent number: 5893867Abstract: A stent positioning apparatus and method are provided for the attachment of a stent to a balloon to be used in the treatment of stenosis, such as coronary angioplasty. In one preferred embodiment, a first generally cylindrical member has a radially deformable wall defining a channel within which the stent and balloon assembly are inserted. A second generally cylindrical member has an opening sufficient to receive the first member with the assembly therein. The second member is then slid longitudinally over the deformable wall of the first member causing nonuniform depressions to be formed in the inner diameter of the stent, thus crimping the stent onto the balloon. Thus, the stent is attached to the balloon without damage and without risk of the stent falling off the balloon prematurely.Type: GrantFiled: November 6, 1996Date of Patent: April 13, 1999Assignee: Percusurge, Inc.Inventors: Celso J. Bagaoisan, Gholam-Reza Zadno-Azizi, Jeffrey F. Field

Patent number: 5851197Abstract: An injector is provided for automatic placement of a subcutaneous infusion set or the like used for delivering a selected medication to a patient. The injector comprises a spring-loaded plunger having a head for receiving and supporting an infusion set in a position for placement of an insertion needle and related cannula through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the infusion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle and cannula. When the plunger head reaches a fully advanced position, with the infusion set placed on the patient, the infusion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector.Type: GrantFiled: February 5, 1997Date of Patent: December 22, 1998Assignee: Minimed Inc.Inventors: April A.

Patent number: 5472317Abstract: A mounting clip is provided for removable mounting of a medication infusion pump of the type used to deliver a selected medication such as insulin to a patient. In the preferred form, the mounting clip comprises a belt clip with a pair of pivotally interconnected and spring-loaded legs adapted for mounting onto a belt or other item of clothing worn by a patient. One leg of the belt clip includes a dovetail key for slide-fit reception into a mating dovetail slot formed in the housing of a medication infusion pump. A detent button is carried on the belt clip at the distal end of a spring arm for snap-fit reception into a detent seat formed in the pump housing, to lock the pump onto the belt clip. The spring arm is manually accessible to permit fingertip retraction of the detent button from the seat, and thereby permit easy sliding removal of the pump housing from the belt clip.Type: GrantFiled: June 3, 1994Date of Patent: December 5, 1995Assignee: MiniMed Inc.Inventors: Jeffrey F. Field, Heather M. Savage

Patent number: 5370622Abstract: A protective case is provided for receiving and supporting a medication infusion pump of the type used to deliver a selected medication such as insulin to a patient. The protective case comprises a transparent housing of impact resistant material for slide-fit reception of the pump, in combination with a seal cap for removable mounting onto the housing to define a substantially waterproof pump enclosure. The seal cap is formed from a resilient shock absorbing material and cooperates with additional shock absorber elements to resiliently support the pump within the housing. A catheter port is formed in the seal cap for sealed passage of a catheter tube extending from the pump to the patient. A belt clip is removably mounted onto the assembled case to prevent seal cap separation from the housing, and to provide a convenient structure for belt mounting of the protective case onto the body of patient.Type: GrantFiled: April 28, 1994Date of Patent: December 6, 1994Assignee: MiniMed Inc.Inventors: John H. Livingston, Ward K. Frye, Jeffrey F. Field
