CATHETER FIXATION DEVICE
20220395670 · 2022-12-15 · ·

A catheter fixation device (10) includes a body (12), a catheter (16) having a proximal portion (18) and a distal portion that passes through an opening (14) in the body (12), and an anti-pull-out lock mechanism comprising an arcuate channel (24) bounded by a pair of arcuate walls (25, 26) extending from a floor of the body (12). A coiled portion (22) of the catheter (16) is constrained to move between the arcuate walls (25, 26) during movement of the proximal portion (18) and the distal portion remains substantially in place.

VACUUM DRESSING FOR USE WITH GUIDE TUBE

Vacuum dressings with a guide tube are provided for implantable medical devices that inhibit infection associated with in-dwelling devices while encouraging healing of the incision around the device. The vacuum dressings mitigate pooling of fluids that harbor bacteria from between the outer diameter of an inserted implantable medical device and the inner diameter of a guide tube and also in the cylindrical gap, between the outer diameter of an inserted implantable medical device and the inner wall of the subcutaneous tunnel, which remains in fluid communication with skin microflora. Implantable medical devices may also illustratively include a variety of catheters, such as venous access, peritoneal dialysis, and other indwelling venous access catheters that require skin penetration; cannulas; Steinman pins; Kirschner wires; and cardiac assist device lines.

Radial Artery Sheath Assembly
20220395280 · 2022-12-15 ·

A radial artery sheath assembly includes a cuff that is wearable around a patient's wrist and a receiver is integrated into the cuff. The cuff is inflatable to compress an incision in the patient's wrist to achieve homeostasis for stopping bleeding. A ring is removably attachable to the cuff and a radial sheath is extendable through the ring to retain the radial sheath in the incision in the user's wrist when the ring is attached to the cuff. The ring is inflatable for compressing the radial sheath in the ring to inhibit the radial sheath from being removed from the incision. A lock is coupled to the ring and the lock releasably engages the receiver in the cuff for attaching the ring to the cuff.

Method and apparatus for rectal anaesthesia

A system and method for delivering a medicament including a catheter configured for implantation in different target tissue sites, extending from a proximal end to a distal end, and having a sidewall which defines an internal lumen. The distal end has one or more apertures in the sidewall for the release of the medicament into the target tissue site; the system also comprises a medicament reservoir fluidly communicable with the internal lumen of each catheter, an adhesive member configured to adhere to the skin of the patient around the exit wound and having an opening therein to allow the catheters to pass through the adhesive member and a retaining member configured to be overlaid on the adhesive member and comprising a guide surface configured to receive a length of the two or more catheters and a plurality of retaining portions to retain the catheters against the guide surface.

Enteric fistula, rectovaginal fistula, and ostomy effluent containment system, and devices and methods thereof
11523932 · 2022-12-13 ·

A skin-safe effluent containment system that may be used to contain fluid leakage from openings in the body of a patient and will adhere to skin in any condition: healthy or injured, wet or dry, smooth, scarred, or uneven. Fluid leakage can occur from natural orifices such as the anus and vagina, spontaneously formed enteric fistulas, rectovaginal fistulas, and surgical openings such as ileostomy and colostomy stomas. The system includes a vacuum-adherent pouch device, comprised of a pouch connected to a porous foam ring which has an air-permeable contact layer on its bottom surface and an air seal on its top surface. The inner and outer perimeters of the foam ring are enclosed and sealed with skin-adhesive materials. When placed on the patient, negative pressure (vacuum) is applied to the foam ring so that the foam collapses and compresses the vacuum-adherent pouch device down against the patient's skin. Negative pressure in combination with the adhesive materials on the perimeters of the foam ring forms a fluid barrier around the opening in the body of the patient so that leakage can be directed into the pouch and drawn away to a separate effluent container.

INTRODUCER LOCK APPARATUS

Apparatuses and methods for retaining a catheter are disclosed. In particular, described herein are apparatuses (e.g., introducer lock apparatuses, devices and systems including them) and methods for securing a catheter relative to an introducer sheath. In particular these apparatuses and method may secure an outer catheter of a mechanical thrombectomy apparatus to prevent the outer catheter from moving proximally when an inner member within the outer catheter is pulled proximally, applying a compression force that would otherwise drive the outer catheter proximally.
